UBS-Axcera Numbering System Explanation The UBS-Axcera numbering system is explained as follows. The following example is for a CU0TC-3 Transmitter system. C – CX Series U – UHF Frequency Band 0 or X - Number of external Power Amplifier drawers T - Transmitter, L - Echo cancelling repeater, R - Regenerative translator C - COFDM (DVB-T/H/T2), I - ISDB-T, D - ATSC, No letter or blank means analog. -3 = 50W or (861 devices), -2 = 30W or (861 devices with smaller power supply), -1 = 3W or 5W depending on the modulation. -4 = 888A. For ATSC there is also a -5 at 150W output but it is the same as the -4. The following example is for a power amplifier drawer CUBP888A-4. 1 | 2 | 3 | 4 | 5 | - | 6 | - | 7 | C U B P 888A - 4 Position Chars Description 1 1 Transmitter Line (C=CX, 6=6X, H=HX) 2 1 or 2 Frequency Band (U=UHF, HV=HB VHF, LV=LB VHF, etc.) 3 1 Version (ex. A-line, B-line, etc. - typically matches transmitter model version) 4 1 Use (E=Exciter/Driver, P=PA) 5 up to 4 Transistor number (might need to abbreviate) 6 1 or 2 Number of transistors in final output stage 7 up to 4 Additional field to include other important info (ex. distinguish bet single or N+1 supplies, or other things not covered in the number CUBP888A-4: Line C, Frequency UHF, Version B, Use PA, Transistor Number 888A, number of transistors in final output stage 4.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Introduction ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 2 Assembly Designators UBS-Axcera has assigned assembly numbers, Ax designations such as A1, where x=1,2,3…etc, to all assemblies, modules, and boards in the system. These designations are referenced in the text of this manual and shown on the block diagram and interconnect drawings provided in Appendix A. The cables that connect between the boards within a drawer or assembly and that connect between the drawers, racks and cabinets are labeled using markers. Figure 1 is an example of a marked cable. There may be as few as two or as many as four Markers on any one cable. These markers are read starting farthest from the connector. If there are four Markers, the marker farthest from the connector is the system number such as system 1 or translator 2. The next or the farthest Marker is the rack or cabinet “A” number on an interconnect cable or the board “A” number when the cable is within a drawer. The next number on an interconnect cable is the Drawer location or Board “A” number. The marker closest to the connector is the jack or connector “J” number on an interconnect cable or the jack or connector “J” number on the board when the cable is within a drawer. 43 2 1 Marker Identification Drawing Safety The Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Transmitter/Regenerative Translator systems manufactured by UBS-Axcera are designed to be easy to use and repair while providing protection from electrical and mechanical hazards.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Introduction ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 7 EMERGENCY FIRST AID INSTRUCTIONS Personnel engaged in the installation, operation, or maintenance of this equipment are urged to become familiar with the following rules both in theory and practice. It is the duty of all operating personnel to be prepared to give adequate Emergency First Aid and thereby prevent avoidable loss of life. RESCUE BREATHING 1. Find out if the person is breathing. You must find out if the person has stopped breathing. If you think he is not breathing, place him flat on his back. Put your ear close to his mouth and look at his chest. If he is breathing you can feel the air on your cheek. You can see his chest move up and down. If you do not feel the air or see the chest move, he is not breathing. 2. If he is not breathing, open the airway by tilting his head backwards. Lift up his neck with one hand and push down on his forehead with the other. This opens the airway. Sometimes doing this will let the person breathe again by himself. 3. If he is still not breathing, begin rescue breathing. -Keep his head tilted backward. Pinch nose shut. -Put your mouth tightly over his mouth. -Blow into his mouth once every five seconds -DO NOT STOP rescue breathing until help arrives. LOOSEN CLOTHING - KEEP WARM Do this when the victim is breathing by himself or help is available. Keep him as quiet as possible and from becoming chilled. Otherwise treat him for shock. BURNS SKIN REDDENED: Apply ice cold water to burned area to prevent burn from going deeper into skin tissue. Cover area with a clean sheet or cloth to keep away air. Consult a physician. SKIN BLISTERED OR FLESH CHARRED: Apply ice cold water to burned area to prevent burn from going deeper into skin tissue. Cover area with clean sheet or cloth to keep away air.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD System Description ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 14 System Description Product Architecture The Innovator CX Series Systems can be configured as DTV Transmitters (i.e CU3TD) or Regenerative Translators (i.e CU3RD). The DTV Transmitter (TD) takes an ASI input and converts it to an On-Channel DTV RF output signal. The Regenerative Translator (RD) accepts an On-Channel RF signal (-79 to –8 dBm) and converts it to an On-Channel DTV RF output signal. If an optional preamp is present in the system, it is connected to the output of the receive antenna and amplifies the weak signal approximately 20 dB. In single drawer systems (CU0TD/RD-1 through CU0TD/RD-5), the CX drawer is configured as a transmitter/repeater with an output power level of 5, 30, 50, 100 or 150 Watts ATSC. In multi drawer systems, the CX drawer is configured as an exciter/driver used to drive additional power amplifier drawers; a single amplifier drawer can operate at 250, 400 or 750 Watts ATSC; two amplifier drawers can operate at 1400 Watts ATSC; three amplifier drawers can operate at 2100 Watts ATSC; and four amplifier drawers can operate at 2500 Watts ATSC. The Innovator CX Series system provides Adaptive Linear and Non-linear correction capability for the transmission path as well as internal test sources that are used during initial system installation. If your system contains the Optional Internal GPS Kit, the output of the GPS Antenna connects to the J5 TNC connector on the rear panel of the CX drawer. This kit supplies 10 MHz and 1 PPS references for use in the CX drawer. CX Drawers The CX drawer contains the (A12) 8VSB ATSC Digital Modulator (1316294), the (A15) Downconverter (1316715) and the (A16) Capture Board (1316716). The drawer also contains the (A6) the Amplifier Assembly, (A7) Output Detector Board (1312207), (A8) the Innovator CX Control Board (1312543), (A10) the +28V/+32V/+42V/+48VDC Power Supply and (A9) the +5V, ±12V Power Supply. To make the system a regenerative translator, the RD kit (1310182) supplies the (A1) 8 VSB Demodulator Board (1308275) for the drawer. The type of (A6) Amplifier Assembly used in the drawer changes as the output power of the system changes. The Amplifier Assembly (1316313) is used in CU0TD/RD-1 systems, the Amplifier Assembly (1312566) is used in CU0TD/RD-2 systems, the Amplifier Assembly (1316636) is used in the CU0TD/RD-3 systems and the Amplifier Assembly (1316035) is used in CU0TD/RD-4 and CU0TD/RD-5 systems. The (A10) Power Supply Assembly also changes as the output power of the system changes. A +48V/300W Power Supply is used in CU0TD/RD-1 systems, a +28V/300W Power Supply is used in CU0TD/RD-2 Systems, a +48V/1100W Power Supply is used in CU0TD/RD-3 systems and a +48V/1100W Power Supply is used in CU0TD/RD-4 and CU0TD/RD-5 systems. When configured as an ATSC Transmitter (TD), the ASI “A” input at (J1) connects directly to the input jack (J30 or ASI IN1), and the ASI “B” input at (J2) connects directly to the input jack (J31 or ASI IN2), on the (A12) 8VSB Modulator Board. The 8VSB Modulator Board automatically selects the ASI “A” or “B” input depending on which input is present.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD System Description ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 15 When configured to operate as a Regenerative Translator (RD), the DTV ON Channel RF Input at (J1 or J5), (-8 to -79 dBm) connects to the Tuner Input Jack on (A1) the 8 VSB Demodulator Board (1308275) supplied with the (RD) kit. The 8 VSB Demodulator Board converts the DTV input to a SMPTE-310 output at (J13), which is connected to the input jack on the (A12) 8VSB Modulator Board. The output of the 8 VSB modulator board at the RF output jack X-502 connects to J1 on the (A6) amplifier assembly. The 8VSB Modulator Board converts the ASI or SMPTE-310M input to a digital RF TV channel frequency in the range of 470-860 MHz. The RF on channel signal is fed to J1 on the amplifier assembly that connects to the ALC Board, Innovator CX Series (1315006), which is used to control the drive power to the RF amplifier chain in the CU0TD/RD-1, CU0TD/RD-2, CU0TD/RD-3, CU0TD/RD-4 and CU0TD/RD-5 Transmitter/Translators. In a CU0TD/RD-1 system, the RF is connected to the (A6) Amplifier Assembly (1316313) that is made up of (A6-A1) the 1W UHF Amplifier Board (1310282) and (A6-A2) the BLF881 Single Stage Amplifier Board (1314882). The assembly has approximately 35 dB of gain. The amplified output at approximately +37 dBm connects to the (A7) Output Detector Board (1312207) which provides forward (2V=100%) and reflected (2V=25%) power samples to the CU Control Board (1312543) for metering and monitoring purposes. In a CU0TD/RD-2 system, the RF is connected to the (A6) Amplifier Assembly (1312566) that is made up of (A6-A1) the 2 Stage UHF Amplifier Board (1308784) and (A6-A2) the RF Module Pallet w/Philips transistors (1300116). The assembly has approximately 36 dB of gain. The amplified output at approximately +38 dBm connects to the (A7) Output Detector Board (1312207) which provides forward (2V=100%) and reflected (2V=25%) power samples to the CU Control Board (1312543) for metering and monitoring purposes. In a CU0TD/RD-3 system, the RF is connected to the (A6) Amplifier Assembly (1316636) that is made up of (A6-A1) 1W UHF Amplifier Module (1310282), the (A6-A2) single Stage UHF Amplifier Board (1314882) and (A6-A3) the RF Module Pallet w/Philips transistors (1316084). The amplified output connects to the (A7) Output Detector Board (1312207) which provides forward (2V=100%) and reflected (2V=25%) power samples to the CU Control Board (1312543) for metering and monitoring purposes. An output power sample is also supplied to the front panel sample jack J15, which is a 50 Ohm BNC type. The typical sample value in a CU0TD/RD-3 is approximately 60dB down from the output power level of the drawer. The RF output is cabled to J9 the “N” connector RF output jack on the rear panel of the drawer. In CU0TD/RD-1, CU0TD/RD-2, CU0TD/RD-3, CU0TD/RD-4 and CU0TD/RD-5 systems the output connects to a digital mask filter, low pass filter and then the antenna for your system. In CU1TD/RD-1, CU1TD/RD-2, and CU1TD/RD-3 systems, the RF output, from the driver drawer, is connected to J1 on the rear panel of the amplifier drawer. The RF is cabled to J1 on the Amplifier Heatsink Assembly in the amplifier drawer. In CU2TD/RD and higher power systems the RF is connected to a splitter and then to the inputs of the amplifier drawers. In systems with vertically mounted amplifier drawers, the RF output connects to the High Power Amplifier Assembly RF Input located on the rear panel of the assembly.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD System Description ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 16 Amplifier Drawers The CU1TD/RD-1 ATSC system is made up of a CX driver drawer and a 250 Watt ATSC amplifier drawer. The driver drawer connects to the 250 Watt amplifier drawer and supplies the needed drive level to produce the 250 Watts output of the system. The control and operating parameters of the 250 Watt amplifier drawer are displayed on the LCD Screen on the driver drawer. In the 250 Watt amplifier drawer, the RF input signal is at J1 on the rear panel of the drawer that is cabled to J1 on the amplifier pallet. In a standard 250 Watt amplifier drawer, a single +42VDC power supply provides the operating voltages, through the current metering board, to the amplifier pallet. In a N+1 250 Watt amplifier drawer, two +42VDC power supplies are diode “ored” and provide the operating voltages, through the current metering board, to the amplifier pallet. If one power supply should malfunction, the other power supply will maintain the necessary voltage to provide the 250 Watts output. The amplified output of the pallet, which has approximately 15 dB gain, is connected to J2 the 7/16” (1.1cm) Din RF output jack of the drawer. An output detector board supplies a forward and a reflected power sample to the amplifier control board for metering and monitoring purposes. The standard CU1TD/RD-2 ATSC system is made up of a CX driver drawer and a 400 Watt amplifier drawer. The driver drawer output connects to the 400 Watt amplifier drawer and supplies the needed drive level to produce the 400 Watts output of the system. The control and operating parameters of the 400 Watt amplifier drawer are displayed on the LCD Screen on the driver drawer. In the 400 Watt amplifier drawer, the input RF signal at J1, located on the rear panel of the drawer, is fed to J1 on the Splitter Board, which supplies two outputs, one to each 888 amplifier pallet. Each amplifier pallet has approximately 14 dB gain. The amplified outputs of the pallets are combined in the 2 Way combiner board whose output is at J1. The RF is connected to J2 the 7/16” (1.1cm) Din RF output jack located on the rear panel of the drawer. The 2 way combiner board supplies a forward and a reflected power sample to the amplifier control board for metering and monitoring purposes. In a 400 Watt amplifier drawer, the typical sample value at J6, a 50Ω BNC jack located on the front panel of the drawer, is approximately 65dB down from the output power level of the drawer. The CU1TD/RD-1 ATSC system w/two dual 888 pallets is made up of a CU0TD/RD-2 drawer and a 500 Watt Amplifier Drawer w/two dual 888 pallets. The CU0TD/RD-1 is used as a driver that connects to the external Amplifier drawer and supplies the needed drive level to produce the 500 Watts output of the system. The control and operating parameters of the 500 Watt Amplifier Drawer are displayed on the LCD Screen on the CU0TD/RD-1 drawer. In the CU1TD/RD-1, the input RF signal at J1 located on the rear panel of the drawer, is fed to J1 on the 2 Way Splitter Board which supplies two outputs; one to each 888A amplifier pallet. Each amplifier pallet has approximately 17 dB gain. The amplified outputs of the pallets are combined in the 2 Way combiner board whose output is at J1. The RF is connected to J2 the 7/16” (1.1cm) Din RF output jack located on the rear panel of the drawer. The 2 way combiner board supplies a forward and a reflected power sample to the amplifier control board for metering and monitoring purposes. In a CU500, the typical sample value at J6, a 50Ω BNC jack located on the front panel of the drawer, is approximately 65dB down from the output power level of the drawer.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD System Description ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 17 The CU1TD/RD-3, 750 Watt ATSC system is made up of a CX driver drawer and a 750 Watt amplifier drawer. The output of the driver drawer connects to the amplifier drawer and supplies the needed drive level to produce the 750 Watts output of the system. The control and operating parameters of the amplifier drawer are displayed on the LCD Screen on the driver drawer. In the amplifier drawer the input RF signal at J1, located on the rear panel of the drawer, is fed to J1 on the 4 Way Splitter Board, which supplies four outputs, one to each 888A amplifier pallet. Each amplifier pallet has approximately 15 dB gain. The amplified outputs of the pallets are combined in the 4 Way combiner board whose output is at J1. The RF is connected to J2 the 7/16” (1.1cm) Din RF output jack located on the rear panel of the drawer. The 4 way combiner board supplies a forward and a reflected power sample to the amplifier control board for metering and monitoring purposes. The typical sample value at J6, a 50Ω BNC jack located on the front panel of the drawer, is approximately 65dB down from the output power level of the drawer. In higher power systems, multiple amplifier drawers are used along with splitters and combiners to produce the desired output. A System Metering Board (1312666) provides forward, reflected, over-temperature and other parameters to the exciter/driver drawer from the external power amplifier chain. The CU2TD/RD is made up of a driver drawer, a two way splitter, two amplifier drawers and a two way combiner with a reject load. The reject load provides isolation protection of the operating power amplifier if the other amplifier fails. One–half the power of the operating amplifier drawer connected to the combiner will be dissipated by the reject load with the other half of the power going to the output filters and the antenna. The CU3TD/RD is made up of a driver drawer, a three way splitter, three amplifier drawers and a three way combiner with reject load. The CU4TD/RD is made up of a driver drawer, a four way splitter, four amplifier drawers and a four way combiner with reject load. The reject loads in the multi-amplifier systems have thermal switches connected to them which monitor the temperature of the load and provide the over-temperature fault, if it occurs, through the system metering board to the exciter/driver drawer. The On Channel RF output of the amplifier drawer either connects directly to the digital mask filter and low pass filter and then to the antenna in single amplifier systems or to a combiner, the digital mask filter, low pass filter, output coupler and finally to the antenna in multiple amplifier systems. The output coupler provides a forward and a reflected power sample to the system metering board which detects the samples and supplies the forward and reflected power levels to the exciter/driver drawer for use in the metering circuits.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD System Description ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 18 Pre-Filter Sample (Non-Linear Distortion) The pre-filter sample from the pre-filter coupler connects to (J3), the RF input 1 jack, located on the rear panel of the driver drawer. This sample connects to the modulator board where it is used in the correction system. Post-Filter Sample (Linear Distortion) The post-filter sample from the post-filter coupler connects to (J4), the RF input 2 jack, located on the rear panel of the driver drawer. This sample connects to the modulator board where it is used in the correction system. IMPORTANT NOTES: RF feedback sample lines must not be disturbed when adaptive pre-correction is enabled. If a sample line is removed, the appropriate pre-correction mode must first be disabled and only re-enabled after the feedback signal is re-connected. RF feedback sample #1 is feedback for the non-linear pre-corrector system and sample #2 is used for the linear pre-corrector system. The adaptive pre-correction systems are likely to be significantly affected if the sense port is moved to another coupler port with a different level or if a sample level is changed significantly (a few dB). If the linear pre-corrector system is exposed to this scenario it may generate a notable ripple in the output that may translate into an increase (or decrease) of the measured RMS level. Should this situation occur, the only way to restore proper operation is to reset the linear corrector using the controller's 'Set To Neutral' command or the web interface's 'Reset Current Curve To Factory' command and allow the pre-corrector system to start over again. The On Channel RF output of the amplifier drawer either connects directly to the low pass filter and digital mask filter and then to the antenna in single amplifier systems or to a combiner, pre-filter coupler, low pass filter, the digital mask filter, post-filter output coupler and finally to the antenna in multiple amplifier systems. The post-filter output coupler provides a forward and a reflected power sample to the system metering board which detects the samples and supplies the forward and reflected power levels to the exciter/driver drawer for use in the metering circuits.

If your system has the optional ASI to S310 Converter, check that it is connected to the AC source.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Unpacking, Installation & ATSC Transmitter/Regenerative Translator Maintenance Instruction Manual, Rev. 2 23 If your system contains an optional preamp check that the 24VDC power supply is connected to the preamp and an AC source. Multi Amplifier Drawer Systems If your system is a CU1TD/RD-1, CU1TD/RD-2 or CU1TD/RD-3, it also contains one amplifier drawer. In CU2TD/RD and higher power systems, multiple amplifier drawers are included. Each amplifier drawer is configured for 230 VAC operation only. Check that the ON/OFF circuit breaker in the CU1TD/RD-1 amplifier drawer, or circuit breakers in N+1 amplifier drawers, CU1TD/RD-2 or CU1TD/RD-3, located on the rear panel on either side of the AC power jack, are OFF. Connect the AC power cord supplied with the drawer from J10 on the rear of the drawer to the 230 VAC source. Refer to Table 1 for the typical voltage and current requirements for CX Systems. AC Distribution Box If the system is mounted in a rack, an AC distribution box wired to a quad receptacle box is used to connect the AC to the individual drawers. The AC distribution box is mounted on the upper right side of the rack accessed through the back of the rack. The main AC input for a C1TD-1 transmitter is, 195-253VAC, at least 10Amps, 50/60Hz. The customer should provide a single point disconnect for the main AC input that connects to the transmitter. The AC input lines connect inside the AC distribution box by first removing the two screws that hold the cover plate to the front of the AC distribution box. Then connect the three wire main AC input to the input lugs, L1 to L1, L2 to L2 and Ground to Ground. The power amplifier drawer and the quad receptacle box connect through AC power cords directly to the AC distribution box. The AC power to the optional receiver drawer and the exciter/driver drawer are connected through AC power cords that plug into the quad receptacle box. AC Distribution Panel If the system is mounted in a cabinet, an AC distribution panel is supplied to connect the AC to the individual drawers. The AC distribution panel is mounted facing the rear of the cabinet and accessed through the back of the cabinet. The main AC input for a CU2TD transmitter is, 195-253VAC, at least 30Amps, 50/60Hz. The customer should provide a single point disconnect for the main AC input that connects to the transmitter. The AC input lines connect to the AC distribution panel by first removing the four #8 screws that hold the cover plate to the front of the AC distribution panel. Then connect the three wire main AC input to the input lugs located at the top left of the AC distribution panel, L1 to L1, L2 to L2 and Ground to the Ground lug on the left.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Unpacking, Installation & ATSC Transmitter/Regenerative Translator Maintenance Instruction Manual, Rev. 2 24 The AC distribution panel in a CU2TD has three circuit breakers that distribute the AC to the individual drawers, which are the Exciter and the two power amplifier drawers. The circuit breakers, which are accessed through the rear door of the cabinet, supply the AC though AC line cords, that connect to the AC input jacks mounted on the rear panels of the drawers. CB1 is a 30 Amp circuit breaker which supplies the AC to the (A2), top, Power Amplifier A drawer. CB2 is a 30 Amp circuit breaker which supplies the AC to the (A3), bottom, Power Amplifier B drawer. CB3 is a 10 Amp circuit breaker which supplies the AC to the (A1) Exciter/Driver drawer.

CX Exciter/Driver Input and Output Connections The CX drawer (CU0TD/RD-1 thru CU0TD/RD-5 system as well as the CU2TD/RD-1 system and higher) rear panel includes a number of input, output and serial connectors that require the user to connect cables to when installing the drawer. When configured as an RD system, the drawer accepts an On Channel RF signal. When configured as a TD system, the drawer accepts an ASI or SMPTE 310M input. In each case, the drawer outputs a digital On Channel RF signal. When the system had been configured as a complete rack/cabinet mounted transmitter system, cables have been installed in the rack/cabinet and hang loosely near the rear panel of the CX drawer when it is pushed all the way into the cabinet. Each cable has been labeled to simplify installation. Please refer to Figure 6 and Table 3 for the locations and information on the CX drawer rear panel connectors. If your system contains the Optional Internal GPS Kit, the output of the GPS Antenna connects to the J5 TNC connector on the rear panel of the CX drawer.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Unpacking, Installation & ATSC Transmitter/Regenerative Translator Maintenance Instruction Manual, Rev. 2 26 NOTES: 1) If your transmitter (TD) system contains an Optional ASI to S310 Converter, connect the ASI output of the STL to the ASI in jack on the rear panel of the converter. Connect the SMPTE-310 Output from the SMPTE 310 Out jack on the rear panel of the converter module to the input jack J1 on the rear panel of the CU0TD/RD-1 thru CU0TD/RD-5 drawer or the driver drawer for the CU1TD/RD-1 and higher power systems. 2) If your transmitter (TD) system contains an Optional K-Tech receiver, connect the RF from the receive antenna or one output of the splitter to the input jack J1 on the rear panel of the K-Tech receiver. Connect the SMPTE 310 Out jack J2 on the rear panel of the K-Tech receiver to the input jack J5 on the rear panel of the CU0TD/RD-1 thru CU0TD/RD-5 or the driver for the CU1TD/RD-1 and higher power systems. 3) If the system contains the optional K-Tech back up system, the K-Tech receiver is bypassed by using the second output of the splitter that connects to J1 on the rear panel of the CU0TD/RD-1 thru CU0TD/RD-5 or the driver drawer and connecting a jumper from J4 to J5, after removing the cable from the K-Tech receiver, on the rear panel of the CU0TD/RD-1 thru CU0TD/RD-5 or the driver drawer. This configuration uses the 8VSB demodulator board in the CU0TD/RD-1 thru CU0TD/RD-5 or the driver drawer to produce the SEMTE-310 signal. 4) If the system contains an optional preamp it connects to the output of the receive antenna and to J1 on the rear panel of the CU0TD/RD-1 thru CU0TD/RD-5 drawer. 5) RF feedback sample lines must not be disturbed when adaptive pre-correction is enabled. If a sample line is removed, the appropriate pre-correction mode must first be disabled and only re-enabled after the feedback signal is re-connected. RF feedback sample #1 is feedback for the non-linear pre-corrector system and sample #2 is used for the linear pre-corrector system. 6) The adaptive pre-correction systems are likely to be significantly affected if the sense port is moved to another coupler port with a different level or if a sample level is changed significantly (a few dB). If the linear pre-corrector system is exposed to this scenario it may generate a notable ripple in the output that may translate into an increase (or decrease) of the measured RMS level. Should this situation occur, the only way to restore proper operation is to reset the linear corrector using the controller's 'Set To Neutral' command or the web interface's 'Reset Current Curve To Factory' command and allow the pre-corrector system to start over again. CX Driver/Exciter Input Connections Connect the On Channel RF Input (RD) –78 to –8 dBm signal, or the ASI Input or the SMPTE-310 Input to the 50Ω BNC input jack (J1 or J5) located on the rear panel of CX drawer. If used, connect the external 10 MHz reference input to the 50Ω BNC 10 MHz input jack (J6) located on the rear panel of the CX drawer. If used, connect the external 1 PPS reference input to the 50Ω BNC 1 PPS input jack (J7) located on the rear panel of the CX drawer.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Unpacking, Installation & ATSC Transmitter/Regenerative Translator Maintenance Instruction Manual, Rev. 2 27 If used, connect the external forward power sample from the pre-filter coupler to the 50Ω BNC Input C jack (J3) located on the rear panel of the CX drawer. If used, connect the external forward power sample from the post-filter coupler to the 50Ω BNC Input D jack (J4) located on the rear panel of the CX drawer. If your system contains the Optional Internal GLONASS or GPS Kit, the output of the GPS Antenna connects to the (J5) TNC connector on the rear panel of the CX drawer. This kit supplies 10 MHz and 1 PPS references for use in the CX drawer. In Translator (RD) systems there is a SMPTE-310 loop-thru from the output of the Demodulator Board at J4, mounted on the rear panel of the transmitter or driver drawer, to the input to the Modulator Board at J5, mounted on the rear panel of the transmitter or driver drawer. There is a jumper installed from J4 to J5. To feed SMPTE-310 directly to the Modulator Board, remove the jumper and insert SMPTE-310 into J5. This is only used in Translator (RD) systems not Transmitter (TD) systems. CX Driver/Exciter Output Connections The digital RF On-Channel output of the CX drawer is the (J9) 50Ω “N” connector RF output jack located on the CX drawer rear panel. CX Driver/Exciter Single Drawer Output Connections In CU0TD/RD-1 thru CU0TD/RD-5 systems, the output of the CX drawer at J9 connects to the low pass, digital mask filter and then to the antenna for your system. CX Driver/Exciter Multi Drawer Output Connections In CU1TD/RD-1 and higher power systems, the output of the CX drawer at J9 is connected to J1 the 50 Ohm “N” connector RF input jack located on the rear panel of the amplifier drawer or to a splitter in multiple amplifier systems. In CU1TD/RD-1, CU1TD/RD-2 or CU1TD/RD-3 systems, check that the system power metering interface cable is connected from J11 the 9 position “D” connector located on the rear panel of the driver drawer to J4 the 9 position “D” connector located on the rear panel of the amplifier drawer. This cable provides the control, status and operating parameters of the amplifier drawer to the driver drawer. In CU2TD/RD and higher power systems the output of the driver drawer is split and connected to J1 the “N” type connector RF input jack on the amplifier drawers. Check that the system power metering interface cable is connected from J11 the 9 position “D” connector located on the rear panel of the driver drawer to J9 the 9 position “D” connector located on the System Metering Board. Also check that the serial connection is cabled from the RJ-45 connector J13 on the driver drawer to the RJ-45 connector J1 on the system metering board. The system metering board provides serial RJ-45 connections at J2 and J5 that are cabled to the RJ-45 serial port J5 on the rear panel of the amplifier drawers. These cables provide the control, status and operating parameters of the amplifier drawers to the driver drawer through the System Metering Board.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Unpacking, Installation & ATSC Transmitter/Regenerative Translator Maintenance Instruction Manual, Rev. 2 28 Power Monitoring Connections to J11 In systems with one or more external amplifiers, J11 is used to communicate the output forward and reflected metering voltages back to the driver. J11 is connected directly to the external amplifier when there is only one external amplifier and is connected through the system metering module when multiple external amplifiers are used. In multiple external amplifier systems there are thermal switches mounted on the output combiner reject loads. The reject load interlock is connected to thermal switches and is used to shut down the system if the reject load overheats. In systems with no external amplifier, the only connection used is the Reject Load Interlock, which must be connected to Supply Return using a jumper from J11-6 to J11-9.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Unpacking, Installation & ATSC Transmitter/Regenerative Translator Maintenance Instruction Manual, Rev. 2 31 HPA Output Connections The amplifier drawer digital RF On-Channel output is at the (J12) 50Ω “7/16” (1.1cm) DIN RF output jack, located on the rear panel of the drawer. The RF output jack is connected to the low pass filter, digital mask filter, then to the antenna for your system in single amplifier systems. In multiple amplifier drawer systems, the outputs of each drawer is connected to a combiner and then the low pass filter, digital mask filter, output coupler and finally to the antenna for your system. The output coupler provides a forward and a reflected power sample that are cabled to the System Metering Board at J8 reflected and J3 forward. Also connected to the system metering board at J10-6 & 9, is the output of the over-temperature switch mounted to the reject load that is used as the reject interlock by the system. The samples and interlock are fed through J9 on the system metering board to J11 on the driver drawer. This completes the connections of the system. Connecting your Transmitter to a TCP/IP Network To connect your transmitter to a TCP/IP Network you must set up the IP address, subnet mask, and gateway values of both the Ethernet controller and the modulator. DHCP is not available for the Ethernet controller but it can be turned on for the modulator controller. However, both devices should use static IP addressing so that these values remain constant after a power cycle. Refer to Figure 54.1.13 on Page 103 for setting up the Ethernet controller and see Figure 31 on Page 67 for setting up the modulator Network parameters. If the transmitter system is pre-wired at the factory and includes a router, the router’s WAN port should be the connection point to the network. The user must configure the router’s WAN port for access to the network. Note: All other devices (Remote Interface panel and CX Exciters) connected to the router have been configured with a static IP address. The operator can access the other devices though the router, but the IP addresses must not be changed. Changing the static IP addresses could prevent communication between the devices and render the transmitter inoperative. Contact your local IT administrator for the proper TCP/IP address subnet mask and gateway settings of your network.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD Unpacking, Installation & ATSC Transmitter/Regenerative Translator Maintenance Instruction Manual, Rev. 2 32 Maintenance The Innovator CX Transmitters are designed with components that require little or no periodic maintenance, except for the routine cleaning of air intakes, fans and module front panels as well as the periodic check of general tightness of hardware. It is recommended that periodically (the time interval depends on the amount of movement the cabinet receives) all mounting hardware, holding drawer slides, shelving and mounting plates inside the cabinet are checked for tightness. All screws and bolts that are accessible should be tightened initially when the transmitter is received and periodically thereafter if the transmitter is moved by vehicle. All coaxial connectors, hard-line connections and hardware holding combiners, splitters, or any other mounted items should be checked and tightened. The amount of time between cleanings of the drawers and cabinets depends on the conditions within the transmitter room. While the electronics have been designed to function even if covered with dust, a heavy buildup of dust, dirt, or insects will affect the cooling of the components. This could lead to a thermal shutdown or the premature failure of the affected drawer. When the front panels of the drawers become dust covered, the drawer should be pulled out and any accumulated foreign material should be removed. NOTE: To remove a drawer from the cabinet, the input and output cables must be removed from the rear (and/or front) of the transmitter before the drawer can be pulled out completely from the cabinet. A vacuum cleaner, utilizing a small, wand-type attachment, is an excellent way to suction out any dirt from the drawer and cabinet. Alcohol and other cleaning agents should not be used unless you are certain that the solvents will not damage components or the silk-screened markings on the drawers and boards. Water-based cleaners can be used, but do not saturate the components. The fans and heatsinks should be cleaned of all dust or dirt to permit the free flow of air for cooling purposes. It is recommended that the operating parameters of the transmitter be recorded from the LEDs and the LCD system metering on the front panel of the drawer at least once a month to be used for comparison purposes in case of a failure. It is suggested that this data be retained in a rugged folder or envelope and stored near the transmitter.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 34 8VSB ATSC Modulator Board The Modulator design is based on the Advanced Universal Modulator board, customized to comply with ATSC standards A/53, A/54 A/64, A/110 and A/153. The modulator converts an MPEG-2 transport stream to an 8-VSB modulated RF signal. Using a new direct digital conversion process, the modulator is able to provide an RF output that covers a standard frequency range of 470 MHz to 1 GHz with superior shoulders and MER. Optionally, the modulator can be configured with an IF frequency range of 30 MHz to 100 MHz or a RF frequency range of 30 MHz to 1 GHz. The modulator supports ATSC features such as 8-VSB modulation, ATSC M/H processing, MFN network mode and SFN network modes with Distributed Transmission. The modulator comes equipped with Adaptive Non-linear and Linear Digital Pre-correction that provide compensation for the non-linear distortions produced by a High Power Amplifier and the group delay introduced by an output filter. The Adaptive Pre-correction support continuous or single run adaptation, provides MER, Peak to Average Ratio, Upper Shoulder, Lower Shoulder and Group Delay measurements and allows the user to store curves on the modulator. The modulator also features Manual Non-linear and Linear Digital Pre-correction. The modulator Controller functions are performed by an embedded controller, based on the PowerPC™ (IBM) processor. The Controller provides all external communication interfaces as well as internal board and peripheral controls. CLI, Web GUI, SNMP and Machine-to-Machine interfaces are all supported. Full remote management and control as well as remote firmware and software upgrades are provided. Control and Communication The modulator can be controlled and monitored locally (on-site), or remotely from a Network Management System (NMS). Control and Communication Interfaces There are two interface ports provided for control and communication: • Ethernet Port (RJ-45) – used for local control with a laptop PC and remote access through a LAN. Web GUI, SNMP and CLI (Telnet and HyperTerminal) protocols are supported. • USB Port (Type B) – used for local control, initial setup, status information and troubleshooting with a laptop PC. A Command Line Interface (CLI) is the supported protocol. SNMP The modulator SNMP interface provides the means for remote management of the modulator and to accept alarm traps. The notification options can be configured on a per-alarm basis. The user may decide to mask certain alarms, increase/decrease integration time to declare an alarm, etc. Alarm and event logs are available via the SNMP interface and are stored in Non Volatile Memory.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 35 Web GUI The modulator hosts an internal web interface (Web GUI) accessible through its Ethernet port. The Web GUI is an intuitive interface allowing the user to access the current modulator status and configure the operational parameters of the system. The Web interface uses a simple hierarchical menu structure which provides access to all modulator parameters. For a detailed description of the Web GUI interface refer to Web GUI Interface. CLI The CLI allows the user to access the current modulator status and configure the operational parameters of the system. The CLI uses a simple hierarchical menu structure which provides access to all modulator parameters. For a detailed description of the CLI interface refer to CLI (Command Line Interface). Local Access The modulator can be controlled and monitored locally (on site) through the Ethernet Port and/or the USB port with a laptop PC. The Ethernet port provides access to the Web GUI and CLI through Telnet. The USB port provides access to the CLI, which allows the operator to perform initial setup/troubleshooting when network connectivity is not available or desired. Remote Access The Network Management System (NMS) operator can control and monitor the modulator remotely through the Ethernet port and LAN using the Web GUI and/or SNMP interfaces. To facilitate the remote control of several modulators, each modulator may be individually named (16 characters). This “name” is available on the control interfaces. Network Parameters The network parameters need to be configured properly to communicate with the modulator on an IP network. This is required to access the Web GUI, SNMP or the CLI on Telnet, as well as for upgrading the main software components. If the default network settings are known and want to be changed, the user can do so with the Web GUI – see Figure 31 for details.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 36 Transport Stream Inputs DVB-ASI Inputs The DVB-ASI inputs accept an MPEG-2 transport stream according to DVB recommendations. Both 188 and 204 byte transport packets are supported. Automatic switching provides near seamless switching to a secondary transport stream if the primary transport steam source fails. SMPTE 310M Inputs The SMPTE 310M input accept a MPEG-2 transport stream. Note: The SMPTE 310M inputs are an optional feature of the ATSC modulator. Modulator Operating Modes The modulator operating modes are Normal and CW. In Normal mode, the modulator generates a complete ATSC (8-VSB) waveform. In CW mode, the modulator generates a narrow-band frequency tone. ATSC M/H Mode The modulator can be configured to process incoming M/H packets created by an M/H pre-processors. Network Modes The modulator can be configured for MFN or SFN network operation. RF Output The RF output covers a frequency range of 470 MHz to 860 MHz in 1 Hz steps. Windowing (Window Enabled) The windowing function is a raised cosine window that reduces the modulation sidebands of the COFDM spectrum. It may be enabled or disabled. Internal Frequency Reference The modulator is equipped with an internal reference frequency that has a stability of ± 0.05ppm, suitable for MFN Mode. Where higher accuracies are required, an external 10 MHz reference signal must be applied to the 10 MHz external reference input.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 37 Manual Digital Linear and Non-linear Pre-correctors The modulator is equipped with digital linear and non-linear pre-correctors (pre-distorters) that can significantly improve the performance of a transmitter. The Pre-corrector function can be switched on and off from the Web GUI or CLI. The Non-linear pre-corrector compensates for power amplifier non-linearity and is able to provide a separate adjustment for the low and high frequency shoulders of the wide channel spectrum. Additionally the non-linearity corrector may serve as peak limiter in order to control peak to average power ratios. The Linear pre-corrector compensates for the group delay created by an output filter. The input-gain of the Pre-corrector can also be used to adjust the power-level of a transmitter. CAUTION! Adjusting the input-gain of the Pre-corrector and thereby the power-level of the transmitter must be carried out with the utmost care, since higher than normal levels may cause damage to the transmitter. The construction of the Pre-corrector curve is aided by a software application that provides a graphical user interface to the Pre-corrector curve. Combined with a spectrum analyzer on the transmitter output, a repetitive process can be carried out to optimize the pre-corrector curve to the actual transmitter. In addition to being a highly effective tool for creating pre-correction curves, the UBS-Axcera Corrector GUI has extensive features for storing and retrieving pre-correction curves to and from the PC storage medium (for example hard disk drive). The UBS-Axcera Corrector GUI also allows storing and retrieving up to ten linear and non-linear curve presets to and from the modulator. The Manual for the Digital Pre-Corrector GUI Software describes in detail the operation of the Pre-corrector. Adaptive Non-linear and Linear Digital Pre-correction The modulator is equipped with Adaptive Non-linear and Linear Digital Pre-correction that provides compensation for the non-linear distortions produced by a high power amplifier and the group delay introduced by an output filter. High power amplifier and band pass filter feedback (reference) signals are downconverted to 25 MHz IF before the “adaptation process” or “cycle” begins. The “adaptation process”, or “cycle”, includes set-up of the capturing cycle, the capturing of data, signal measurements, the calculation of NLP/LP coefficients and the transfer of coefficients and signal measurement to the modulator board. Once the capturing cycle is set up, the downconverted HPA or BPF reference signal is sampled by an ADC and stored in a local memory buffer for the processor to read upon completion of the data capturing process.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 38 The processor compares the captured data to the ideal waveform curves (stored on the capture card) and calculates NLP or LP coefficients. The coefficients are then transferred to the modulator board for control of the back-end Non-linear or Linear Digital Pre-corrector. A number of signal measurements, including MER, Peak to Average Ratio, Upper Shoulder, Lower Shoulder and Group Delay are also transferred to the modulator board and are displayed by the modulator interfaces (Web GUI, CLI). Web GUI Interface Introduction The modulator parameters can be reviewed or changed using the Web GUI interface. The Web GUI is an intuitive interface allowing the user to access the current modulator status and set up the operational parameters. The Web GUI interface uses a simple hierarchical menu structure which provides access to the modulator parameters though a series of pull down menus. The modulator needs to be assigned an IP address in order to access the Web GUI. The modulator is shipped from the factory with a default IP address, but the user will need to configure the IP address of each unit for local network access. The IP address can be accessed and modified from the front panel or CLI. Login • Open a Web browser window (Internet Explorer, Firefox, etc.) and enter the modulator IP address. For example: http://172.20.30.210/. • The first menu page is the login page. • The User Name field must be kept blank, while the default password for normal access is “admin” Figure 5: 8-VSB Modulator Login Page

SFN OFF, ON If this parameter is set to ON, the modulator will operate in SFN mode and a number of additional parameters can be edited by the user. Table 8: MFN Transmission Parameters When the modulator is used in conjunction with a UBS DTx Adapter, the user must configure the modulator’s Transmitter ID (tx_address) correctly, so that the TCP command information used to address the individual modulator (transmitter) is extracted. The Transmitter ID is a 12-bit unsigned integer, with a user configurable range of 0 to 4095. The Transmitter ID’s decimal value is equal to the DTx Adapter’s three character hexadecimal string, which is determined by the DTx Adapter’s tx_group_ number and tx id. For example, a tx_group_number of “AB” and a tx id of “9”, would generate a 3 character hexadecimal string of “AB9”. In this case, the user must enter a Transmitter ID of 2745. A tx_group_number of “DE” and a tx id of “15”, would generate a 3 character hexadecimal string of “DEF”. In this case, the user must enter a Transmitter ID of 3567.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 52 Digital Adaptive Pre-corrector The Digital Pre-corrector page allows the user to configure the capture card cycle (adaptation process) settings and store the NLP and/or LP Profiles (coefficients) into memory. Pre-correction Set-up The user should first select which pre-correction cycles will be run by configuring the “NLP/LP Selection” parameter. The user may select Non-linear Pre-correction (NLP), Linear Pre-correction (LP) or both. The user should also select how many NLP cycles will run for every LP cycle. When the modulator is synchronized with a 1PPS reference signal (from a GPS receiver), the user can offset the cycle start time, relative to the 1PPS signal. Note: The NLP cycle will always run before the LP cycle when both cycles are selected. The user must then select the “NLP Method” to determine which pre-correction algorithm is used. The user should first try “Regression” mode. If the results are undesirable, the user should then try “RLS” mode, then “Legacy” mode. The user must then select the “Mode” parameter and set the “Precorrection” parameter to “Run” to start the cycle(s) (adaptation process). When the “Mode” parameter is set to Adaptive, the NLP and/or LP coefficients will be optimized constantly. When the “Mode” parameter is set to “Single Operation”, the NLP and/or LP coefficients will only be optimized once. If the “Precorrector” parameter is set to “Stop”, the NLP and/or LP cycles will stop, with the last calculated coefficients being used. In other words, the cycle(s) will stop, but the Non-linear Pre-correction and/or Linear Pre-correction will not be disabled. To disable the pre-correction, the “Precorrection” parameter must be set to “Stop” and “Reset Precorrector” must be set to “ON”. Setting “Reset Precorrector” to “ON” while the cycle(s) have stopped will clear the NLP and LP coefficients. Note: Any time a parameter is changed (i.e from NLP to NLP/LP) the user should first Stop the Precorrection then Reset the Precorrection prior to changing the parameter. This excludes saving NLP or LP profiles. Storing a Profile (Curve) to Memory To store the active Profile (coefficients) to memory, the user must set “Save Adaptive NLP Profile” or “Save Adaptive LP Profile” to “ON”. Before saving, the user should configure the “Profile Name” and “Profile Number” accordingly. Loading a Profile (Curve) from Memory A NLP or LP Profile can be loaded from memory using the Non-linear or Linear Pre-corrector pages – see the Non-linear and Linear sections. The user must select the desired profile from the NLP or LP Profile pull-down menu and ensure that the NLP or LP State is set to “ON”.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 53 Note: If the user has saved a profile (curve) to memory and decides to stop the Adaptive Pre-correction process, the user should navigate to the Non-linear and/or Linear Pre-corrector pages and select the desired profile from the pull-down menu and ensure that the state is set to “ON”. This will ensure that Non-linear and/or Linear Pre-correction is enabled following a modulator reset and that the correct profile (curve) is loaded.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD 8VSB ATSC Modulator ATSC Transmitter/Regenerative Translator Instruction Manual, Rev. 2 74 SNMP The modulator supports a SNMP interface for remote management of the modulator via a SNMP Network Management System (NMS). Refer to SNMP Parameters and NMS Users Menu on how to use the Web GUI to configure the SNMP interface and set up a NMS user account. Once the SNMP interface is established it is possible to use standard SNMP Network Managers (e.g., SNMPc, HP OpenView etc.) or a custom SNMP Network Manager for SNMP access. SNMP Traps can be emitted for each of the possible modulator alarms. The required Management Information Base (MIB) file for the modulator SNMP interface can be included on the manual CD delivered with the unit and is available upon request. The SNMP parameters list is nearly identical to those used in the Web GUI and CLI. The exceptions are the controls for creating a NMS User account and the management of modulator configuration files for backup or software upgrades. This set of functions is purely local to each modulator and is not suitable for SNMP global access. Of course, these functions are still accessible for remote access via the system web interface or CLI interface. Below is the menu tree for the web interface. The items enclosed in a grey box are excluded from the SNMP interface. All other menu items are accessible via SNMP.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Initial On Site Transmitter/Regenerative Translator Turn On Procedure Instruction Manual, Rev. 2 82 Initial On Site Turn-On Procedure After the Innovator CX Series drawer or drawers are installed and all input, output and AC connections are made, the system is ready for the initial on site turn on. Check that the output of the transmitter is connected to an appropriate rated load or to the digital mask filter and the antenna for your system. Check that the main AC power to the System is ON. If your system contains an optional ASI to S310 converter module, K-Tech receiver drawer or Axciter, check that they have AC connected to them and that they are turned ON. NOTE: If your system is mounted in a cabinet and contains an optional UPS, check that the ON/OFF button, located on the left side of the top panel of the UPS is On. The UPS is normally mounted behind the removable blank panel, located immediately above the exciter/driver drawer, which is held in place by four #10 Phillips head screws. Single or Multi Drawer Systems If you have a CU0TD-1 thru CU0TD-5 system, push ON the switch located on the rear panel of the drawer above the AC power jack. The large fan mounted on the rear panel of the drawer should operate. If your system is a CU1TD/TD-1 or higher power system, switch ON the ON/OFF circuit breaker(s), located on the rear panel of the amplifier drawer(s), mounted on each side of the AC input power jack. The two fans mounted in the amplifier drawer should operate. Place the system in Operate. The Operate/Standby LED and Status LEDs on the CU0TD-1 thru CU0TD-5 should be Green indicating the system is in Operate and performing normally. The Operate/Standby LED showing Amber indicates the System is in Standby. The Status LED showing a blinking Red LED indicates an Event (Fault) is occurring now. The Status LED showing Amber indicates that an Event (Fault) occurred since the last time the Event (Fault) indications were reset. NOTE: The modulator takes approximately 2 minutes to lock up for normal operation. During this time the modulator status screen will blink warm up. If your system is CU1TD/RD-1 or higher power, the Enable LED and Status LEDs on the Amplifier Drawer should be Green indicating the system is in Operate and performing normally. The Enable LED showing Amber indicates the System is in Standby. The Status LED should be Green indicating no Events (Faults) in the system. If the Operate/Standby LED shows Amber it indicates that the System is in Standby. If the Status LED is blinking Red it indicates an Event (Fault) is occurring now. If the Status LED shows Amber it indicates that an Event (Fault) occurred since that last time the Event (Fault) indications were reset. The output power is factory set according to customer request and does not need adjusted. If a problem occurs, call UBS-Axcera field support at 724-873-8100 for information on modifying the power level of the system. Once the modulator has finished its boot up process it can be configured for LAN access. Using the Web GUI, navigate to the System parameters sub-menu where the Network parameters can be configured. After changing any Network parameters, the modulator must be reset. Navigate to the System parameters sub-menu System Reset page to reset the modulator. The modulator can now be provisioned remotely through the Web GUI.

The RF System Interlock at J12-5 provides the customer with a means of connecting the system to protection circuits, for the loads, thermal switches, combiners, or the antenna, in the output of your system, that will place the system in Standby if the protection circuit opens. The Reject Load Interlock is provided at J11, a 9 position “D” connector. J11-6 provides the customer with a means of connecting the system to protection circuits, for the reject load in multiple amplifier systems, which will place the system in Standby if the protection circuit opens. If the interlocks are not used in your system, a plug with a jumper from J12-5 to J12-15, ground, for RF system Interlock and another plug with a jumper from J11-6 to J11-9, for Reject Load Interlock, need to be connected. These jumpers provide the RF System and Reject Load Interlocks, which allow the system to go to operate. Without the jumpers, the system will remain in Standby. Adaptive Pre-Correction Set-up Procedure Adaptive Pre-correction is available as limited One-Touch Correction (OTC) or full feature correction. With One-Touch correction the adaptive process can be enabled for one cycle whereas full feature correction can be set to continuously adapt or automatically adapt when performance characteristics indicate that a change is needed.

Figure 57: Typical Event Log Page This page allows the user to view events and to determine the time between events. Events are logged in the order they are received. If more than 200 events are detected, the transmitter's System Controller drops the oldest event to record the new event. Transferring of events from the transmitter's System Controller and the Ethernet Controller is scheduled so that device details are continuously monitored. Therefore the event log page may update a few seconds behind the transmitter display when the log is full or changing quickly. Each event record indicates the event number, the number of events, an occurrence counter and text describing the event. The occurrence counter keeps track of the number of times a specific event has occurred since the log was last cleared. Up to 99 occurrences are available for each event. To view the next set of twenty events, activate the 'Next' button. If viewing events higher in the log, the 'Previous' button allows you to return to prior events. The user can return to the main control/monitoring page by selecting the 'Back' button.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Web Ethernet Transmitter/Regenerative Translator Interface Description Instruction Manual, Rev. 2 104 Configure Page The user can access the Configure page by selecting the 'Configure' button on the CX Ethernet Controller main control/monitoring page. Figure 58: Configure Page NOTE: The Innovator CX Ethernet controller does not use DHCP addresses – TCP/IP settings must be fixed and entered manually. A crossover cable may be needed if connecting directly from a computer to the Innovator CX drawer. Note: If the transmitter system is pre-wired at the factory and includes a router and Remote Interface Panel, CX drawers connected to the router have been configured with a static IP address. The operator can access the CX drawers though the router, but the IP addresses must not be changed. Changing the static IP addresses of the CX drawers could prevent the drawers from communicating with other devices in the system and render the transmitter inoperative. When entering a site ID, be sure to not use special characters except underscores, dashes, and forward slashes. The page above displays SNMP parameters and allows an operator to send a test trap. If this system did not have SNMP enabled, then fields would not be populated and the 'Send Test Trap' button would not be present. New event log entries including an activated test trap are automatically forwarded to SNMP agents specified to receive trap messages. Trap messages do not need to be acknowledged by an agent. Changes to the transmitter's output power are available to administrators when the transmitter is operating. Once changed, the menu defaults back to the main display page and the systems forward power is noted as changing. To manage user accounts, administrators may click the ‘Manage Accounts’ button near the top of the configure page.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC SNMP Ethernet Transmitter/Regenerative Translator Interface Description Instruction Manual, Rev. 2 106 SNMP Interfaces The Innovator CX Ethernet Controller implements Simple Network Management Protocol (SNMP). SNMP is a standardized method of transferring information from one electronic device to another. SNMP is typically used to remotely control and monitor several transmitter devices from a centralized network management system (NMS). SNMP is a communication method between two applications and is not a graphical user interface. Therefore, SNMP functionality is included along with web page server functionality. SNMP is used to gather information or set control states but it requires additional computer applications for operator monitoring and control. The Innovator CX Ethernet Controller implements SNMP version 2 (SNMP v2), using a Management Information Base (MIB). The MIB file defines all SNMP parameters of the transmitter, specifies the format of data, and orders the presentation of the parameters using a hierarchical namespace containing object identifiers (OID). Each OID identifies a variable that can be read, read and set, or only set via SNMP commands. SNMP functionality also provides for alert messages that are issued from the Ethernet Controller to one or two network computers. A SNMP trap message is sent only once and is not acknowledged by the receiving device. The Ethernet Controller issues a trap message when data is added to the transmitter Event log (either activation of a fault or when a fault is cleared), or when the transmitter operate/standby status changes. SNMP Configuration The Ethernet Controller's TCP/IP Address, Subnet Mask, and Gateway must be configured with static values that are valid within your network. Dynamic Host Configuration Protocol (DHCP) is not implemented; however access to these configuration parameters is available through the front panel setup menus of the Innovator CX drawer. The Innovator CX drawer’s SNMP MIB allows up to two SNMP trap destinations. The trap destination values can be set through WEB pages. The TCP/IP address of a trap processing computer can also be configured through the SNMP parameters called 'site_trap_adr1' and 'site_trap_adr2'. To clear a previously configured trap destination and cause the system not to issue traps to a specific address, set the value to '000.000.000.000'. Reading of SNMP values is done with the message's community access set to 'public'. When setting SNMP values, a default community access level of 'private' is used. Future implementations of the Ethernet SNMP agent may allow for the set community access level to be defined through the device's web server.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Board Descriptions Transmitter/Regenerative Translator Instruction Manual, Rev. 2 108 Descriptions of Boards in the CU0TD/RD-1 thru CU0TD/RD-5 Systems (A1) 8 VSB Demodulator Board (1308275) NOTE: The 8 VSB demodulator board is only used in RD systems except when the output of an external K-Tech Receiver is used. Overview The 8 VSB demodulator assembly receives an off air 8 VSB signal on any VHF or UHF channel and demodulates this to an MPEG-2 transport stream that is per the SMPTE-310M standard. The input to the assembly is at an “F” style connector on the shielded tuner and can be at a level of –8 to –78 dBm. The tuner (TU1) down converts the RF channel to a 44 MHz IF signal. This signal is the input to the digital receiver chip U1. The digital receiver chip subsequently decodes the IF and delivers an MPEG-2 transport stream on a parallel data bus to a programmable logic array, U8. U8 clocks the asynchronous MPEG data from the receiver chip and outputs a synchronous data stream at a 19.39 MHz rate to buffer/driver U11. U11 subsequently drives the output at J13 to a lower level that is AC coupled out of the board. Microcontroller Functions A microcontroller, U17, is provided on this assembly to supervise the operation of the receiver chip and the tuner. In addition, the microcontroller also interfaces to the front panel LCD display via connector J24 and pushbutton interface on J27. On power up, the microcontroller sets the tuner to the last channel that was selected when the unit was powered down. In addition, the microcontroller also configures the digital receiver to operate as an 8 VSB receiver. The communication between all of the devices on this board is via an I2C serial bus that is local to this board. Jumper and DIP Switch Settings This board can be used in various assemblies. When this assembly is installed in the Innovator CXB product, the jumpers on J7 and J8 should be placed between pins 2 and 3 for normal operation. The DIP switch SW1 should be configured as indicated in Table 12.

(A5) ALC Board, Innovator CX Series(1315006) Pin AttenuatorJ1RF InputInput LossDetectorAuto/Man SelectALCTP4Mute from Control CircuitJ2RF OutputTP1Overdrive DetectOutput PowerReflected PowerInput PowerReference Figure 60: ALC Board Block Diagram The ALC Board, Innovator CX Series, is used to control the RF drive power to the RF amplifier chain in the CU0TD/RD-1 thru CU0TD/RD-5 systems. The board accepts an 8-VSB RF input signal at a nominal input level of -3 dBm average power and amplifies it to whatever drive level is necessary to drive the final RF amplifier in the drawer to full power. The input signal to the board at J1 is split by U4, with one half of the signal driving a PIN diode attenuator, DS1 and DS2, and the other half driving a detector, U13, that is used to mute the PIN attenuator when there is no input signal. The output of the PIN attenuator is sent to two cascaded amplifiers, U2 and U3, which are capable of generating +10 dBm average power from the board at J2. The PIN attenuator is driven by an ALC circuit or by a manual fixed voltage bias, depending on the position of switch S1. When the switch is pointing to the left, looking from the front of the drawer, the ALC circuit is enabled. When the switch is pointing to the right, the ALC circuit is disabled and the PIN attenuator is controlled through the Manual gain pot R62. When the switch is in either ALC or manual, the voltage in the unused circuit is preset low by the circuitry connected to pins 4-6 on SW1. This allows the RF power to ramp up slowly to full power when the switch changes positions. CR8, C33 and associated components control the ramp up speed of the manual gain circuit. CR9, C42 and their associated circuits do the same thing for the ALC circuit. The practical effect of this is to preset the RF drive power to near zero output power when enabling and disabling the ALC, followed by a slow controlled ramp up of power. The ALC circuit normally attempts to hold the drawer output power constant, but there are four faults that can override this. These faults are Input Fault, VSWR Cutback Fault, VSWR Shutdown Fault and Overdrive Fault.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Board Descriptions Transmitter/Regenerative Translator Instruction Manual, Rev. 2 110 The Input Fault is generated by comparator U7C and presets the PIN attenuator and ALC circuit to maximum attenuation whenever the input signal drops below about -7 dBm. Test point TP2 allows the user to measure the detected input voltage. The VSWR cutback circuit is set so that the ALC circuit will start reducing RF drive once the Reflected power reaches a level of about 6% and will keep reducing the drive to maintain that level. The cutback is generated by U8A, U8B and their associated components that diode-or the metering voltages. The forward power is scaled to 2V = 100 % and the reflected power is scaled to 2V = 25%. The Reflected metering voltage is doubled again by U8B so that when the voltage of U8B exceeds the voltage at the output of U8A, the reflected power takes over the ALC circuit. Once the U8B voltage drops below the forward power at U8A, the forward power takes over again. The VSWR shutdown circuit will shut the drawer down if the Reflected power increases to 15% or higher, which can happen if the drawer sees reflected power when the ALC is in manual. The Overdrive protection looks at a sample of the RF signal that is applied to J1 of the board. The peak level of this signal is detected and can be measured on TP1. This voltage is applied to a comparator with the threshold set by R38. If this threshold is exceeded, the ALC circuit mutes then ramps up to try again. This circuit also works in manual gain as well.

The input RF connects to the first amplifier stage U2, which has a gain of approximately 14 dB. The output is split by U2 and connected to the final amps. The final amplification circuit consists of parallel-connected push-pull LDMOS amplifier circuits Q1 and Q3 operating in class AB each with approximately 14 dB of gain. The board uses a power supply voltage of 28-32V. The RF transistors are operated at a voltage of 24V generated by the voltage regulators U1 for Q1, U5 for Q3 and U6 for Q2, which provide a separate regulated voltage to each transistor. In order to match the LDMOS impedance to the characteristic impedance of the input and output sides, matching networks are located before and after the amplifier circuits. The hybrid coupler U2 splits the input to the parallel amplifiers and the hybrid coupler U4 combines the amplified outputs. The combined output connects through a directional coupler to J1, the RF output jack of the board. The directional coupler provides an RF sample at J3 that is used by an external overdrive protection circuit located on (A5) the ALC Board. The RF output of the board is being used as a driver and has a level of 3W maximum 8-VSB. At this power level the board draws approximately 1.8A total from the power supply.

R7 is the reflected power calibration pot and R23 is the forward power calibration pot. A Forward power sample, -10 dBm, connects to J4 on the board, which is cabled to the front panel sample jack of the drawer. The RF output of the board, typically +46 dBm, is at J2, which is cabled to J9 the RF Output Jack of the drawer. The (1312207) output detector board can be used as either an average, for digital, or peak, for analog, detector board using jumpers on J5 and J6. (A8) Control Card, Innovator CX (1312543) The Innovator CX control board provides the overall system control for the CX system. There are two main elements of the board, U7 and U9. U7 is a programmable logic device that is loaded with firmware, which provides the overall system control. It decides whether or not to allow the system to generate RF output power, and turns the +40 VDC power supply on and off depending on whether or not it is receiving any faults, either faults generated on board, or faults generated externally. The second major component of the board is the microcontroller U9, which controls the front panel indications and drives the display. The U9 microcontroller is not involved in the decision making process, U7 does that. Rather, it is layered on top of U7 and is the EPLD's interface to the outside world. Information is passed between the microcontroller and the EPLD. The microcontroller communicates information to and from the front panel and sends the EPLD the information it needs to decide whether or not to allow the system to turn on. The front panel viewable LEDs DS3 for Operate/Standby and DS4 for Status indicate the current operating condition of the system are mounted on and controlled by this board. The U9 microcontroller can also communicate, using the Optional Ethernet Kit, with a daughter card that allows the user to view remote control parameters via a web Ethernet interface. The ±12 VDC and +5 VDC from the (A9) power supply and the 39-42 VDC from the (A10) power supply are routed to the other boards in the drawer through this board. The +40 VDC power supply operates all the time, and connects the 39-42 VDC to the board at J19-1, 2, & 3 with 5 common. Q13 on the control board is turned on and off to gate the 39-42 VDC, which connects through J19-6, 7 & 8, to the RF output stages. The ±12 VDC and +5 VDC input voltages to this board is connected through J21 and filtered before being connected to the rest of the board. +12 VDC connects through J21-1, +5VDC through J21-2 & 3, and -12 VDC through J21-6. Common connections for the input voltages are connected to J21-4 & 5. The ±12 VDC and +5 VDC are used on this board and also routed to the other boards in the drawer through this board. The +3.3 VDC for the microcontroller and programmable logic array, mounted on the board, is provided by the voltage regulator IC U6 from the filtered +5 VDC input. The output of U6 can be adjusted to +3.3 VDC using R120.

See the chart above. The 115VAC or 230VAC input to the CU0TD/RD-1 thru CU0TD/RD-3 drawer connects through the AC power cord at J6, the power entry module located on the rear panel of the drawer. The CU0TD/RD-4 & CU0TD/RD-5 drawer only operates with 230VAC. An On/Off 10A/250VAC circuit breaker is part of the power entry module. With the circuit breaker switched On, the (L) line input is wired to F1 a 10 Amp fuse for over current protection. The AC lines are connected to terminal block TB1, which distributes the AC to (A9 and A10) the two DC power supplies. There are two varistors, mounted on TB1, connected from the line input to neutral and to ground for surge protection. The AC in the CU0TD/RD-4 & CU0TD/RD-5 also connects to the (A11) fan mounted on the rear panel of the drawer. The fan will run when AC is applied to the drawer and the circuit breaker is switched On. The +5VDC and ±12VDC outputs of the (A9) power supply connects to the terminal block (TB2) that distributes the DC to the boards in the drawer. Some of the +5VDC and ±12VDC outputs connect directly to the 8 VSB Demodulator and 8 VSB Modulator The +28/+42/+48VDC outputs of the (A10) power supply connect to the (A8) CX Control Board, which then supplies the switched +28/+42/+48VDC VDC to the (A6) Amplifier Assembly. In CU0TD/RD-1 thru CU0TD/RD-3 drawers the DC output of the (A10) power supply also connects to the (A11) fan mounted on the rear panel, which will operate when AC is applied to the drawer, the On/Off circuit breaker is On and the (A10) power supply is operating.

SW1
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Board Descriptions Transmitter/Regenerative Translator Instruction Manual, Rev. 2 117 The Amplifier Control Board uses a Programmable logic device, U12, to control the amplifier drawer. It takes an enable signal from an external driver drawer, and turns the power supplies on whenever the driver has told it to turn on, unless it detects faults internal to the drawer. The board monitors the forward and reflected power, the heatsink temperature, the pallet currents, and the power supply voltage and will generate alarm signals if any of those parameters exceed safe limits. The amplifier drawer has no front panel display other than a two LEDs, one for Status and one for Enable. The board sends all its output information, including the forward and reflected levels, back to the driver drawer, through J4, so the information can be displayed on that drawer's LCD Display. The board will generate a Red Blinking Status LED if it detects an alarm, fault, prompting the operator to look at the LCD display on the driver drawer to see what fault has occurred. A CUB transmitter System can have up to 4 external amplifier drawers and since they are all the same, without differences in the wiring harness, there needs to be a way to identify which amplifier drawer is which. The rotary switch SW1 is used to specify the amplifier ID number which generates a unique serial address so that the individual amplifier drawers will respond when polled for information. The +5 VDC inputs to this board are routed through J4-8 and J5-8. The +5 VDC inputs are diode Or connected so that either the +5VDC from the (A8) power supply or the +5VDC from the (A9) power supply will operate the board. The +5VDC is split with one output connected to U1 a voltage regulator IC, which provides +5V and +5V_ANALOG as outputs. The +5 VDC is filtered before being connected to the rest of the board. The other +5 VDC output is connected to the regulator IC U2 that supplies +3.3 V to the microcontroller and programmable logic array. (A10) Current Metering Board (1309130) The current metering board measures the current into the RF output amplifier pallets and supplies this value to the control board. In the single pallet amplifier drawer, there are two sensing circuits which are used. In the multiple pallet amplifier drawer, there are four sensing circuits which are used. Each circuit has two parallel .01Ω series current sensing resistors and a differential input IC that supplies a voltage output that is proportional to the current for metering purposes. The +42VDC from the (A8) power supply connects to TB2 and TB4 on the board. The +42VDC from the (A9) power supply connects to TB8 and TB10 on the board. The +42VDC input at the TB2 input senses the current to the (A1) 878 output amplifier pallet through TB1 on the board. The +42VDC input at the TB4 input senses the current to the (A2) 878 output amplifier pallet through TB3 on the board. The +42VDC input at the TB8 input senses the current to the (A3) 878 output amplifier pallet through TB7 on the board. The +42VDC input at the TB10 input senses the current to the (A4) 878 output amplifier pallet through TB9 on the board. The two or four sensing circuits are identical therefore only one will be described. For the (A1) 878 amplifier pallet, the +42VDC from the (A8) switching power supply connects to TB2. R1 and R2 are the parallel .01Ω current sensing resistors which supplies the voltage values to the U1 current sense amplifier IC. R11 is a gain adjust, which is adjusted to eliminate any rSense Error and to place the OpAmp output at 2.61V for 40Amps sense as measured at TP3. The current sense output at J1-1 connects to the (A7) control board for metering purposes.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Board Descriptions Transmitter/Regenerative Translator Instruction Manual, Rev. 2 118 (A5) 2 Way Splitter Board (1313158) The 2-way splitter board takes the RF Input at J1 (≈12.5 Watts ATSC) on the board and splits it into two equal outputs (≈5Watts ATSC), which are connected to the inputs of the two 878A or 888A amplifier pallets at J1. (A5) 4 Way Splitter Board (1308933) The 4-way splitter board takes the RF Input at J1 (≈11Watts ATSC) on the board and splits it into four equal outputs (≈4.75Watts ATSC), which are connected to the inputs of the four 878A amplifier pallets at J1. (A1-A4) 878A Amplifier Pallets (1314098, 1313170 or 1310138) There are two 878A Amplifier Pallets mounted on the two pallet Amplifier Heatsink Assembly and there are four 878A Amplifier Pallets mounted on the four pallet Amplifier Heatsink Assembly. Each of the 878A pallets has approximately +16dB of gain for the UHF frequency range of 470 to 860 MHz. The pallets operate Class AB and generate 150 Watts ATSC with an input of 4.75 Watts ATSC. (A1-A2) Dual 888A Amplifier Pallets (1314173) There are two 888A Amplifier Pallets mounted on the two pallet Amplifier Heatsink Assembly. Each of the 888A pallets has approximately +16dB of gain for the UHF frequency range of 470 to 860 MHz. The pallets operate Class AB. (A1-A4) 888A Amplifier Pallets (1315347) There are four 888A Amplifier Pallets mounted on the Amplifier Heatsink Assembly. Each of the 888A pallets has approximately +15dB of gain for the UHF frequency range of 470 to 860 MHz. The pallets operate Class AB and generate approximately 230 Watts ATSC with an input of 8 Watts ATSC. (A6) 2 Way Combiner Board (1313155) The 2 way combiner board takes the two RF Inputs at J4 & J5 (≈230Watts ATSC) on the board and combines them to a single output (≈375Watts) at J1, which is connected to J2 the 7/16” (1.1cm) Din RF output jack of the drawer.

Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Board Descriptions Transmitter/Regenerative Translator Instruction Manual, Rev. 2 119 (A8 & A9) One, two & three pallet Amplifier Drawer Power Supplies The 230VAC, needed to operate the drawer, connects through the AC power cord at J3, the power entry module located on the rear panel of the drawer. The AC lines are connected to a terminal block TB1 to which the circuit breaker(s) connect. In a N+1 one pallet amplifier drawer and all multiple pallet amplifier drawers, there are two On/Off 20A/250VAC circuit breakers that are mounted on the back panel of the drawer on either side of J3 the AC input jack. With the circuit breakers switched On, the AC is distributed to the two (A8 and A9) DC power supplies. In a standard one pallet amplifier drawer one 20 Amp circuit breaker CB1 connects the AC to the (A8) DC power supply. TB1 has three varistors (VR1-VR3) connected across the AC input lines for surge and over voltage protection. The AC input from TB1 also connects to through 2 amp fuses to the two fans (A11 & A12) mounted in the drawer. Both fans will run immediately when AC is applied to the drawer. The +5VDC for the operation of the amplifier control board in the drawer is generated by the (A8 & A9) power supplies at J1-9 on each power supply. The +5VDC from the (A8) power supply connects to J4-8 and the +5VDC from the (A9) power supply connects to J5-8 on the control board. The +5VDC is produced when AC is connected to the drawer and the CB1 and/or the CB2 circuit breakers are turned On. Either or both power supplies provides the +5VDC for use by the control board. The +48VDC needed by the amplifier modules on the heatsink assembly is generated by the (A8 & A9) power supplies in the amplifier drawer. In a standard single pallet amplifier drawer there is only the (A8) power supply. The power supplies will operate when AC is connected to the drawer, the CB1 circuit breaker for the (A8) power supply and the CB2 circuit breaker for the (A9) power supply, are turned On and a Low is provided on the Inhibit Line that connects to J1-6 on the power supplies from the control board. The CB1 circuit breaker supplies the AC to the (A8) power supply which provides the +48VDC to the (A1) and (A2) 878 amplifier pallets. The CB2 circuit breaker supplies the AC to the (A9) power supply which provides the +48VDC to the (A3) and (A4) 878A amplifier pallets. Descriptions of External Boards Used in Transmitters w/Multiple External Amplifier (A5) System Metering Board (1312666) Note: The external System Metering Board is only used in Transmitters with multiple external Amplifier Drawers. The function of the System Metering Board is to detect forward and reflected output power samples and generate output voltages that are proportional to the power levels of the sampled signals for use by the control monitoring assembly in the exciter/driver drawer. There are two identical signal paths on the board: one for forward power and one for reflected power. A sample of the forward output power, from the external (A11) output coupler, enters the board at the SMA jack J3. The signal is filtered and connected to resistors R5, R3 and R6 that form an input impedance-matching network to Pin 3 on U1. The forward power signal is detected by the RF detector IC U1. The detected output at pin 7 is split with one half connected to the forward average calibration pot R7, digital, which adjusts the level of the signal connected to Pin 11 on U2.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Board Descriptions Transmitter/Regenerative Translator Instruction Manual, Rev. 2 120 The other half of the split is connected to the peak calibration pot R18, analog, which adjusts the level of the signal connected to Pin 8 on U2. U2 is a Bilateral Switch IC whose output, digital or analog, is controlled by the selection of the modulation type in the exciter/driver drawer. In this BTC transmitter the average, digital, output connects to the amplifier IC U3A that is wired to the SYS_FWD and RMT_FWD Power Metering Outputs. A reading of 2 VDC measured at TP1 is equal to a 100% Forward Power reading on the meter. The SYS_FWD level connects to J9 on the board that is cabled to J11 on the exciter/driver drawer for use in the control monitoring assembly. The RMT_FWD level connects to J10 on the board for use by remote control and monitoring. A sample of the reflected output power, from the external (A11) output coupler, enters the board at the SMA jack J8. The signal is filtered and connected to resistors R26, R22 and R27 that form an input impedance-matching network to Pin 3 on U6. The reflected power signal is detected by the RF detector IC U6. The detected output at pin 7 is connected to the reflected calibration pot R25, which adjusts the level of the signal connected to the amplifier IC U3B that is wired to the SYS_RFLD and RMT_RFLD Power Metering Outputs. A reading of 2 VDC measured at TP2 is equal to a 25% Reflected Power reading on the meter. The SYS_RFLD level connects to J9 on the board that is cabled to J11 on the exciter/driver drawer for use in the control monitoring assembly. The RMT_RFLD level connects to J10 on the board for use by remote control and monitoring. +12 VDC enters the board at J9-1, from the exciter/driver drawer and is connected through a filter and isolation circuit consisting of C31, C14 and L5 before it is connected to the regulator IC U5. U5 supplies the +5 VDC needed for operation of the ICs on the board. The +5 VDC is connected through a filter circuit consisting of C15, C19 and C21 before it is connected to the rest of the board. (Optional) ASI to S310 Converter Module NOTE: The ASI to S310 Converter Modules is only used with STL ASI feed inputs. The ASI to SMPTE 310M converter takes the STL ASI feed input, if present in your system, and converts it to a SMPTE 310M output which connects to the input to the UBS-Axcera system. The converter contains an ASI Motherboard (1311179), an ASI to 310 Conversion Board, Non-SFN (1311219) or ASI to 310 Conversion Board, SFN (1309764), and a 120 VAC to +12 VDC converter module. ASI Motherboard (1311179) The ASI motherboard takes the +12 VDC, from the 120 VAC to 12 VDC converter module, and converts it to +5 VDC and +3.3 VDC which are used by the ASI to S310 conversion board. U1 is a regulator IC that supplies an output of +5 VDC at J2-7 that connects to the ASI to 310 converter board. U2 is a regulator IC that supplies an output of +3.3 VDC at J2-11 that connects to the ASI to 310 converter board. Also +12 VDC is wired to J2-3 that connects to the ASI to 310 converter board. The ASI motherboard is the mounting platform for the four LEDs that are displayed on the front of the module. The LEDs will be Green if everything is OK or Red if the indicated function is malfunctioning.
Innovator CU0TD-1/CU0RD-1 – CU4TD/CU4RD ATSC Board Descriptions Transmitter/Regenerative Translator Instruction Manual, Rev. 2 121 The LEDs are Power, which indicates +12 VDC is connected to the converter, FIFO ERROR, which indicates an overflow or underflow condition in the input buffer, S310 Lock, which indicates the converted S310 signal is in a locked condition, and ASI Lock, which indicates the recovered ASI signal is in a locked condition. ASI to 310 Conversion Board, Non-SFN (1311219) The ASI signal is input to the ASI to S310 conversion board via J1. U2 de-serializes the ASI input signal into a parallel byte stream. The parallel byte stream is clocked into U6 which buffers and converts it to a valid S310 bi-phase encoded signal. Null packets are added or dropped during this process to obtain the valid 19.393 Mb/s output. U6 is also responsible for re-stamping the PCR clock. The final S310 output of the board is at J5. ASI to 310 Conversion Board, SFN (1309764) The ASI signal is input to the ASI to S310 conversion board via J1. U2 de-serializes the ASI input signal into a parallel byte stream. The parallel byte stream is clocked into U6 which buffers and converts it to a valid S310 bi-phase encoded signal. For SFN operation the ASI payload must be 19.392568 Mb/s +/- 2 ppm. A 38.785317 MHz VCXO locks to the exact S310 bit-rate using a Digital PLL. This method ensures the extracted S310 stream is frequency locked without modifying its content i.e. add/drop null packets, PCR restamp, etc. The final S310 output of the board is at J5. (Optional) K-Tech Receiver NOTE: If your system contains an (Optional) K-Tech Receiver, information on the receiver is contained in the separate manufacturers supplied instruction manual.
