Revision 1.03 viii ChannelMaster TX7 Transmitter
Revision 1.03 Description 1-1 1. PRODUCT DESCRIPTION 1.1 Introduction Nucomm’s ChannelMaster TX7 is a Digital-Analog Portable Microwave Transmitter. The tripod mounted Micro-wave Transmitter System is designed to operate in any specified band in the 1.00 GHz to 15.5 GHz frequency range. Each unit is field programmable and configurable to meet a wide range of customer requirements. The TX7 may be configured for dual band or tri-band operation. The ChannelMaster TX7 is designed to be an extremely flexible system. It is fully integrated with an MPEG2 compli-ant super-low delay Encoder, a Multi-mode Digital Modulator, and an Analog FM modulator. Outputs include ASI and microwave RF in the frequency bands mentioned above. The CMTX7 design uses advanced software defined radio techniques and supports both COFDM and VSB digital modulation. As additional digital modula-tion formats become available, the sys-tem software can easily be updated to support them. The ChannelMaster TX7 includes inputs for Composite Video, HD-SDI and SD-SDI, ASI, Firewire, and 70 MHz modu-lated signals. The system comes standard with two analog audio channels or one digital AES channel. Optionally, the system can support four analog audio channels or two digital AES channels. The system features an LCD display for control and monitoring, an easy to use menu driven user interface, fifteen user defined presets, field programmable RF and Audio Sub-carrier frequencies, ad-justable RF power, and integrated dy-namic color bars. A built-in serial inter-face can be used for remote control and monitoring. Special menus have been included to ease the BAS (US) reloca-tion process. Available options include a high power amplifier, multi-band operation, and standby power sourcing. Contact Nu-comm for information about additional options. This manual covers all configurations and options for the series within the 1.00 GHz to 15.5 GHz frequency range.
Revision 1.03 1-2 ChannelMaster TX7 Transmitter 1.2 Model Numbering Scheme Given the model number, a unit's configuration can be determined using the following: AAAAA – CMTX7 – BB – CCC – YZ Options Specified Frequency Plan Power Output Model Generalized Frequency Band Designator Where: AAAAA = mean frequency band center in GHz rounded to the closest GHz. This num-ber is then multiplied by 10. For multiple bands, each center frequency designation is separated by a backslash "/". BB = Used to identify the power output, per the following Power Output Designators: Power Output is represented by Letters for the analog power (as listed in the table be-low), and Numbers (0-9) for the digital power. For example, a 5W Analog / 2W digital system would be described with a power indicator of "E2". A Dual-Band system would have two sets of power indicators, to show the power levels at both bands. LETTER DESIGNATOR Analog Power (Watts) A 1 B 2 C 3 E 5 J 10 L 12 Example: For A Dual Band 2 + 7 GHz radio with these power ratings: 2 GHz: 12 Watt Analog, 5 Watt Digital 7 GHz: 5 Watt Analog, 1.5 Watt Digital AAAA/AAAA = 20/70, and BB/BB = L5/E1.5
Revision 1.03 Description 1-3 Thus the above model number be similar to: 20/70-CMTX7-L5/E1.5-CCC-YZ CCC = Nucomm assigns a frequency plan number for each unique frequency channel combination. Contact your Nucomm representative for further information. YZ = Miscellaneous options as listed in the table below. The model number is formed by appending as many letter codes as appropriate. LETTER CODE OPTION AUDIO A2 2 AUDIO A4 4 AUDIO B AES ENCRYPTION X XLR AUDIO MODULATION + VIDEO C2 COFDM / FM C4 COFDM / HD ENABLED C8 COFDM / FM / HD ENABLED C10 FM ONLY C12 COFDM / FM / VSB / HD ENABLED C15 COFDM / FM / VSB / HD READY C17 COFDM / FM / HD READY Options that are not a standard part of the system are indicated in this manual by shaded text as shown here.

Revision 1.03 5-2 ChannelMaster TX7 Transmitter tions from the default screen with the Quick Knob. System navigation is via the rotary "Quick Knob" switch (See Figure 5-1) to the right of the LED display. Turn the "Quick Knob" clockwise or counter-clockwise to move the cursor through the DEFAULT screen selections or the menus. By pressing the "Quick Knob", you are able to select or activate items. The "Quick Knob" may also be referred to as the “Enter” button or “the Wheel.” 5.1.1 Changing Characters 1. Begin by rotating the “Quick Knob” until the desired screen item is hightlighted. Press Enter to select the item. 2. The left-most character position of the name will then be highlighted. Rotate the “Quick-Knob” until the desired alpha-numeric character appears. 3. Press the “Quick-Knob” to save the character. 4. Move the cursor to the second character by rotating the “Quick-Knob”. 5. Press the “Quick-Knob” to select the character. 6. Rotate the “Quick-Knob” until the desired alpha-numeric character appears. 7. Again, Press the “Quick-Knob” to save the character. 8. Repeat Steps 2 thru 7 until either the desired name is assigned or all character positions are filled. On certain screens (as with system set-tings), an arrow is used to show the cur-rent setting, as in the following where "SDI" is currently set: Note the highlighted arrow at the bot-tom left of the screen. This highlight-ing is the "cursor", and indicates an item that is ready to be selected. Note: After one minute of inactivity the display reverts to the DEFAULT screen, and any un-activated selections are dis-carded. 5.2 Front Panel Buttons Modulation Mode The ChannelMaster modulation mode is set to ANALOG or DIGITAL using the “DIGI/ANLG” Button. Pressing the “DIGI/ANLG” Button tog-gles the ChannelMaster between Digital and Analog modulation modes. An LED and a confirmation message indicate that the mode change is being made. Switching to Digital Mode
Revision 1.03 Operation 5-3 Switching to Analog Mode Set Power Level The user can toggle between HI or LOW power by pressing the “HI/LO” Button. The LCD will then immediately display the change. Unit in Low Power Mode 5.2.1 Changing Operating Frequency (Requires Frequency Direct Mode. See Sec. 5.9.1.) 1. Ensure that the Main Menu screen is displayed on the LCD. 2. Rotate the “Quick-Knob” to highlight the preset parameter to be changed. 3. Press the “Quick-Knob” to enter the selection. 4. Rotate the “Quick-Knob” to adjust the value of the selection. 5. Press the “Quick-Knob” to enter the changed value. 6. Rotate the "Quick Knob" until the digit that needs to be changed is highlighted. 7. Press "Enter". 8. Change the digit as needed. 9. Press "Enter". 10. Repeat until all digits are correct. 11. When all digits are correct, move the cursor to the end of the fre-quency where it says “GHz”. 12. Press "Enter". When the operating frequency is changed, the unit goes into standby while the synthesizer re-tunes to the new frequency. Transmission resumes when the new frequency is reached. Note: If offset channel operation is de-sired, the user is cautioned to ensure they have adequate authorized spec-trum to avoid illegal operation. For ex-ample, in the US post-Nextel 2 GHz band plan, which stipulates 12 MHz channels with 3 MHz offsets, use of 7 MHz or 8 MHz modulation bandwidths on an offset channel would result in out of channel emissions and potential ad-jacent channel interference. Thus, for this example, 6 MHz modulation band-width should be used when using offset channels with Channels 1-7 in the US 2 GHz post-relocation band plan. 5.3 Using Presets There are 15 user definable Presets. These Presets are accessed using the numbered “Preset” Buttons, or through the “PRE” Button. The numbered Preset Buttons (1 through 5) are located just below the LCD. These five numbered preset keys are provided to rapidly store and recall custom configurations without requiring any menu navigation. There are three banks of Presets: Pa1-Pa5, Pb1-Pb5, and Pc1-Pc5.

Revision 1.03 5-6 ChannelMaster TX7 Transmitter TX MODE The TX MODE button is used to select from the following operating modes: • NORMAL: Transmitter is active, with or without an input signal. • STANDBY:Transmitter is in STANDBY until switched to another mode. Frequency synthesizer is locked on frequency. • VID STBY: Controls the transmitter behaviour when a signal is not detected on the input port. The system can be set to either go to Standby or transmit the internally generated test bars. • VID STB l at this time. AUDIO Quick Key The AUDIO quick key provides a short-cut to the audio settings. (Note: the Au-dio button is not present on the optional XLR front panel.) When modulating digitally, the system will display the Encoder's audio settings as if you had selected the following menu items: Menu>Encoder>Audio. (Refer to Section 5.5; Encoder Menu Selections.) When modulating in analog, the system displays the FM audio settings, as if the following items were selected: Menu> Modulation> Parameters> FM> Audio. (Refer to Section 5.5; FM.) 5.4 Status Indicators & Test Gen The following show the unit's status: RF (Green): RF present at output port. Test Gen LED (Amber): Color Bars are active. Alarm (Red): Indicates an improper setting or a module failure. The exact reason for the alarm can be deter-mined from the Alarm section of the Main Menu. Remote: Unit is under remote control. Video (Green): Indicates that video is present. TEST GEN This button toggles the internal color bars “on” and “off,” and allows editing of the 16 character ID, as well as selection of the tone levels. TEST GEN may only be selected when the input type is set to COMPOSITE or SDI.
Revision 1.03 Operation 5-7 When TEST GEN is enabled, the LED will light and the LCD will display the screen shown above. The ID can be edited from this screen. To modify the TEST TONE levels, scroll the wheel to the right twice and the TONE LEVEL screen will appear. The tone levels can be set from -26dBFS to -10dBFS. When the TEST TONE is “on,” the left channel contains a continuous tone and the right channel has a pulsing tone. 5.5 Main Menu Selections The user can customize the Channel-Master TX7 operation (rather than us-ing the factory defaults) through the Main Menu. After pressing the MENU Button , the Main Menu Screen will appear. From the Upper Level Menu, the user can select one of six sub-menus to ac-cess. They are: • Input Menu • Modulation Settings Menu • Encoder Settings Menu • System Settings Menu • Monitoring Menu • Alarms 5.6 Input Menu Selections The Input Menu selections are depend-ent on whether the unit is set for Analog or Digital modulation (Section 5.2). Only one input can be made active at a time. The Input Menu controls the ac-tive input, regardless of any signals pre-sent on the input connectors. When digital modulation is selected, the available input selections are: Composite - The signal is converted to digital via the MPEG Encoder and routed to the digital modulator. SDI - The signal routes through the MPEG Encoder and then to the digital modulator. External 70 MHz Digital - This input bypasses the encoder and modulator, and routes to the heterodyne up-converter. ASI - Input bypasses the Encoder and goes to the digital modulator. (The ASI rate must be at or below the maximum digital modulation rate.) Firewire – The MPEG2 data is extracted and sent to the digital modulator.
Revision 1.03 5-8 ChannelMaster TX7 Transmitter When analog modulation is selected, the available input selections are: Composite - The composite signal is routed through the internal low pass filter (bandwidth ± 4.0 MHz NTSC, ± 5.6 MHz PAL typical) then sent to the FM modulator. Note: To input Baseband video, set the video filter to “Bypass.” See sec. 5.7.1. SDI - Internal circuits convert SDI inputs to Composite. The signal is then processed as Composite. External 70 MHz FM - This input bypasses the modulator, and routes to the heterodyne up-converter. 5.7 Modulation Menu Selections The Modulation Menu establishes the operating parameters for both Analog and Digital modulation schemes. The Modulation Menu has two sub-menus: • Mode Select • Parameter Setup Mode Select is used strictly for select-ing the type of Digital Modulation to be utilized. Choices are COFDM, DVB-S, and VSB. Parameter Setup allows the user to change or adjust the various parameters affecting the different modulation types: • FM • COFDM • DVB-S (Future) • VSB 5.7.1 FM For FM (i.e. Analog FM Modulation), there are two sub-categories: Audio, and Video. AUDIO Under the FM Audio sub-menu, the user can choose between any one of four Analog audio channels (SC1L, SC1-R, SC2-L, & SC2-R) and change any of the following: • Input: Off, Line/Line, Line/Mic, Line/Mic+PP, Tone, AES/EBU, and Embedded • Insertion: Adjusts from –40 dB to –20 dB; (default –28 dB.) • Gain: Adjusts from –6 dB to +6 dB; (default 0.0 dB) • Frequency: Adjusts sub-carrier frequency. (Refer to table in Sec-tion 5.7.1. Audio Sub-carrier Frequencies.) If Line/Line is selected, the unit accepts balanced 600 Ω inputs at +8 dBm Ana-log (–10 dBu Digital). At 1 kHz input, headroom is +18 dBm Analog (0 dBu Digital). If AES is selected, the unit accepts digi-tal AES audio on Audio 1 (and Audio 3 in a four audio unit). If only two audio channels are configured, they will be the first channel in Group 1. If Embedded is selected, the audio data embedded in the incoming SDI stream will be used. This selection will only be available when SDI input is selected.
Revision 1.03 Operation 5-9 A 1 kHz Tone can be activated. The tone is steady on the left channel, and intermittent on the right channel. When Line/Mic is selected, the unit is set to accept a line input on the left con-nector, and input from a microphone on the right connector. The microphone in-put range is -4dB to +41dB. This option is only available on models with front panel XLR inputs. When Line/Mic+PP is selected, the unit is set to accept a line input on the left connector, and input from a microphone on the right connector. Phantom power is output on pins 2 and 3 of the right connector to power the microphone. The microphone input range is -4dB to +41dB. This option is only available on models with front panel XLR inputs. VIDEO Under the FM Video sub-menu, the user can change any one of four selec-tions. They are: • Inverse: Normal, Inverse • Emphasis: Emphasis, Flat • Filter: Bypass, 3.90 MHz, 4.50 MHz, 4.75 MHz, 5.60 MHz. (In PAL mode only 5.60 MHz and Bypass are available.) The filter setting allows you to groom the incoming video signal bandwidth. Setting the filter to bypass allows for input of Baseband video. • Deviation Bandwidth: (Display Only) 5.7.2 COFDM For the COFDM (Digital) sub-menu, the following parameters can be changed: • Power: On, Off • Constellation: QPSK, 16QAM, 64QAM • Code Rate (error correction):1/2, 2/3, 3/4, 5/6, 7/8 • Guard Interval (guard spacing - delay between intervals): 1/32, 1/16, 1/8, 1/4. • Bandwidth: 6 MHz, 7 MHz, 8 MHz Note: Adjusting these settings modifies the data rate. COFDM Guidelines The COFDM Data Rate is determined by manipulating Guard Interval, Code Rate, Bandwidth and Constellation, per the COFDM Data Rate tables in Section 5.7. As a rule of thumb, select the COFDM parameters in this order: 1. Use the lowest data rate required to pass the necessary data. 2. Use the maximum Bandwidth al-lowed by your spectrum man-ager(s). 3. Choose the minimum Constella-tion (i.e. Modulation System) set-ting that will allow the data rate required. For example, don’t use 16QAM if enough data can be transmitted using QPSK. 4. Adjust the GI (Guard Interval) and CR (Code Rate). (a) The GI, or "safety bits", help allow COFDM to operate in mul-
Revision 1.03 5-10 ChannelMaster TX7 Transmitter tipath environments (around buildings, across water, etc) by increasing the time delay be-tween data segments. Increasing the GI (1/4 is the maximum set-ting) increases link robustness but reduces the overall data rate, as less time is made available for payload transmission. Con-versely, moving the GI towards 1/32 (the minimum) decreases link robustness but allocates more bits to payload. (b) The CR controls how much error correction overhead is in-cluded in the data stream. To compensate for a poor link, mov-ing the CR towards 1/2 (maxi-mum error correction) increases link robustness as bits are re-allocated from payload to error correction. Moving the CR towards 7/8 (minimum error cor-rection) allocates bits from error correction to payload. COFDM Data Rate Tables 5-1 through 5-3 show the data rates which can be achieved by modify-ing the COFDM parameters. Note: When inputting ASI signals, the data rate should be set to approximately 1-2 kbps above the ASI input rate.

Alarms are reported when errors occur during the operation of the ChannelMas-ter TX7. The alarm may be the result of a detected broken communications link or an improper input (etc.), and not the fault of the unit itself. Regardless of the problem, the Alarm LED will illuminate, and the LCD will flash a text message stating the alarm problem.
Revision 1.03 5-16 ChannelMaster TX7 Transmitter 5.10.2 ALARM Working in conjunction with the Alarms function, the Alarm History List allows the user to view any active alarm(s) cur-rently affecting the system. When the alarm problem is resolved, the alarm will disappear from the listing.
Revision 1.03 Operation 5-17 5.11 BAS Relocation Settings For our US clients, the ChannelMaster is designed so that, when properly config-ured per the following guidelines, you will only need to change one setting on one screen when it’s time to switch over to the “post-relocation” 2 GHz band plan. To preset the unit to allow a “one setting” switchover, there are two groups of set-tings that must be made in advance: “AUDIO SUB-CARRIER FREQUENCY” and “CHANNEL BANDWIDTH & BAND PLAN”. These are described below. 5.11.1 Audio Sub-Carrier Frequency In this section, you set your “pre-relocation” and “post-relocation” Audio Sub-Carrier (ASC) frequencies, so that when you make the switchover they will be ready to go. Start the ASC set-up procedure by making the following menu selections: MENU>MODULATION>PARAMETER SETUP>FM>AUDIO This brings up a screen similar to the one at right, with the settings and selections as described below. All ASC’s are modified in the same fashion. ASC#1 is used as the example. 2(17)/7/13 This setting controls the frequency for the selected Sub-Carrier when op-erating in the “pre-relocation” 2 GHz band (USA), as well as for all the other frequency bands (i.e. 7 GHz or 13 GHz). The possible range for this setting is 4.83 MHz to 8.5 MHz. (Refer to Section 5.2.1 - Changing Oper-ating Frequency.) 2(12) 1-7 This setting controls the frequency for the selected Sub-Carrier when op-erating in the “post-relocation” 2 GHz band (USA) on channels 1 through 7. The possible range for this setting is 4.83 MHz to 5.8 MHz.

Revision 1.03 5-18 ChannelMaster TX7 Transmitter 2GHz Freq Plan: 2G(17), 2G(12) BW(2G(17)/7/13): 4MHz, 3MHz BW(2G(12)8-10): 4MHz, 3MHz 5.11.2 Channel Bandwidth and Band Plan In this section, you can set your “pre-relocation” and “post-relocation” Video Bandwidth Deviation, so that when you make the switchover they will be ready to go. Start by making the following menu selections: MENU>SYSTEM>BAS. (Note: If the BAS screen is not visible then it must be enabled by selecting MENU>SYSTEM>OPTIONS>BAS MENU=YES.) This brings up the screen at right, with the settings and selections as described below: 2GHz Freq Plan This setting controls the 2 GHz Frequency Plan, which will be used by the radio. Select the 17 MHz “pre-relocation” band-plan by choosing “2G(17)”, or the 12 MHz “post-relocation” band-plan by choosing “2G(12)”. BW(2G(17)(7/13) This setting controls your Video Deviation bandwidth when oper-ating in the “pre-relocation” 2 GHz band (USA), as well as for all the other frequency bands (i.e. 7 GHz or 13 GHz). The possible selections are 3 MHz or 4 MHz. BW(2G(12) 8-10) This setting controls the Video Deviation bandwidth when operat-ing in the “post-relocation” 2 GHz band (USA) on channels 8 through 10. The possible selections are 3 MHz or 4 MHz. NOTE: Due to bandwidth limitations of the “post-relocation” 2 GHz band-plan, in “2G(12)” mode, the Video Deviation bandwidth of 2 GHz channels 1 through 7 is locked at 3 MHz. 5.11.3 Switchover to “Post-relocation” Settings For our US clients, when your DMA switchover date arrives, assuming you have already set the unit per the preceding guidelines, you will only need to take the following steps to put the radio on the new “post-relocation” settings: Step #1: Navigate to the following menu: MENU>SYSTEM>BAS Step #2: Change your “2 GHz Freq Plan” setting from “2G(17)” to “2G(12)” Step #3: Done!
