iSTRATA TX Operator’s Guide/Tech Ref ManualNote To User - RF ExposureMPE CalculationRF ExposureMicrowave Radio Communications (MRC) provides this warning for safety purposes with the intent to inform the user of the potential hazard to RF exposure. The following guidelines for safe operation were derived from OET bulletin 65, August 1997, as recommended by the Federal Communications Commission (FCC).The 6.4 - 7.125 GHz STRATA transmitter is a mobile transmitter designed to provide services to broadcast ENG users under CFR 74 subpart F and 74.601 TV pickup stations. This unit, operated without an antenna, will not create RF energy exceeding 1.0 mW/cm2, the FCC limit for exposure. Once connected to an antenna, the potential for harmful exposure will be greatly enhanced.In this situation, a certain distance from the radiator is to be maintained. Calculations need to be performed to understand what that safe margin for exposure is. This is known as the Maximum Permissible Exposure (MPE) limit.Calculations provided are for common antennas often utilized in the ENG environment. The following formula used is that suggested by OET 65.Calculating MPEEIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * PP = RF power delivered to the antenna in mWG = Power gain of the antenna in the direction of interest relative to an isotropic radiatorR = distance to the center of radiation of the antenna in centimetersS = MPE in mW/cm² (milliwatts per square centimeters)ConversionsdBi to numeric gain = Antilog (dBi/10)Feet to centimeters = Feet * 30.48Centimeters to Feet = cm * .03284 π = 12.57User InputRF power delivered to the antenna = WattsAntenna gain (referenced to isotropic antenna) = dBiDistance from the center of radiation = FeetCalculation steps:1.

Note: At frequencies above 1500 MHz, S must not be greater than 1ReferenceFCC OET Bulletin 65, August 1997 - Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic FieldsFigure 1 and Figure 2 show the maximum exposure distance for various antennas. One plot provides the maximum permissible output of the STRATA transmitter for analog modulation, and the other plot for digital modulation.MRC, in accordance with the requirements set forth by the FCC, provides this information as a guide to the user. It is assumed that the users of this equipment are licensed and qualified to operate the equipment per the guidelines and recommendations contained within the product user guides and in accordance with any FCC rules that may apply.Figure 1: Analog ModulationFigure 2: Digital Modulation Estimated Permissible Exposure@ 2.7 Watts Digital RF Powerfor STRATA 6.425 - 6.525 and 6.8875 - 7.1255 GHz.00.511.520 2 4 6 8 10121416182022242628303234363840Distance in FeetPower Density (mW/cm^2)0dBi5dBi16dBi20dBi35.7dBiEstimated Permissible Exposure@ 4.0 Watts Analog RF Powerfor STRATA 6.425 - 6.525 and 6.8875 - 7.1255 GHz.00.511.520 2 4 6 8 10121416182022242628303234363840Distance in FeetPower Density (mW/cm^2)0dBi5dBi16dBi20dBi35.7dBi

Do not exceed +36 VDC input power or damage will occur.
Product Description 2-4STRATA TX Operator’s Guide/Tech Ref ManualPower Options The STRATA TX System configurations operate on +28 VDC power, supplied externally. This DC power can be supplied by the optional STRATA ACU, or from another DC power source. Contact your Sales Representative for the latest details.Note A TCU and TXU are defined as being “co-located” when the TXU and TCU are physically separated by not greater than 6 feet.If the TXU and TCU are co-located, power must be supplied to each unit through their individual power connectors from the same power source. See Figure 2-2. Do not use DC on coax to power the TXU or TCU when the units are co-located.Figure 2-2: Powering the TXU and TCU IndependentlyIf your installation calls for separating the TXU and TCU, the TXU is powered by DC supplied by the TCU or the TCU is powered by DC supplied by the TXU. The DC power is superimposed on the coaxial cable connected between the units. See Figure 2-3 and Figure 2-4. The DC input voltage to the unit co-located with the DC power supply must be greater than +24 VDC. STRATA TCUDC Power (+28 V)STRATA TXUBranched Power CableRefer to the “Installation” Chapter on page 6-1 (part of the STRATA TX Technical Reference Manual only) for additional information.For those applications that use a TCU in a standalone mode, i.e., to generate ASI or DVB-S signals, DC power from the TCU to the TXU or from the TXU to the TCU cannot be used.Figure 2-3: Powering the TXU from the TCUFigure 2-4: Powering the TCU from the TXUSTRATA TXUSTRATA TCUDC Power (+28 V)Up to 600 ft.(180 m)CoaxPower CableSTRATA TCUSTRATA TXUDC Power (+28 V )CoaxUp to 600 ft.(180 m)
Product Description 2-5STRATA TX Operator’s Guide/Tech Ref ManualDC power superimposed on the coaxial cable between a TCU and a TXU can be supplied from either the TCU or TXU, depending upon the location of the DC power supply. Coaxial cable length/voltage limitations exist when powering from either the TXU or TCU. These limitations are based on cable size, DC voltage input, cable resistance, and cable length. A maximum length of 600 feet (180 meters) between the TXU and TCU is supported. Contact MRC Technical Support for more information on cable requirements.DC power required for a STRATA TX System depends upon the TX System configuration, i.e., if the TXU or TCU are operated in a standalone mode, if the TXU and TCU are co-located, or if the TXU and TCU are mounted in separate locations. See Figure 2-5 on page 2-6 for the various STRATA TX System configurations available.For TX Systems that use DC power sources other than a STRATA ACU, contact MRC Technical Support for additional power information.2.2.6 Mounting and Deployment OptionsThe STRATA TX offers a number of options for either mobile or portable applications. For more details on installation of the STRATA TX in various applications, see the “Installation” Chapter on page 6-1 (part of the STRATA TX Technical Reference Manual only).Mobile Installation For mobile applications such as in a vehicle or in an aircraft, the STRATA TX System is usually mounted in an MRC fixed mounting bracket and is installed in a bulkhead or compartment. The cabling is permanently installed and power comes from aircraft or vehicle power. Portable Deployment In portable applications, the STRATA TX System will be moved from place to place and set up each time. The TXU and TCU will usually be mounted in a MRC universal mounting bracket. The bracket is attached to a tripod using a mounting plate and quick release. The cabling between the TXU and TCU is typically left in place and the power, antenna, and audio/video connections are removed at the end of each deployment. 2.2.7 System IntegrationSystem Communication When the TXU and TCU are connected, they automatically communicate via signals superimposed on the coaxial cable between the two units. This allows them to share information on installed hardware, preset configurations, current status, and alarms.System Operation Once the TXU and TCU are connected and communicating, the units work seamlessly together. System settings can be selected and modified from the front panel of either unit, regardless of which unit holds the hardware being configured. System Configuration The STRATA TX System offers two levels of system configuration, designed to match the needs of different personnel.For the field operator, the STRATA TX System has up to 9 Presets that can be selected from the front panel. Each Preset controls key parameters such as modulation, frequency, and audio and video settings. Additional settings that are front panel- controlled include band, channel, offset, and filtering.For the advanced operator and technical staff, the STRATA TX Configurator software allows complete control of all parameters in the STRATA TX System. The STRATA TX Configurator software runs on a Windows-based PC and connects to either the TXU or the TCU via an RS-232 serial interface cable.
Product Description 2-6STRATA TX Operator’s Guide/Tech Ref ManualInterfacing a PC to either the TXU or TCU in a connected system gives you complete control of both units. You can read the current settings, program new settings, or return the units to their factory default settings. The STRATA TX Configurator software automatically detects what hardware is installed in the system and assigns the appropriate configuration to the correct hardware, regardless of which unit holds the hardware being configured.

Product Description 2-7STRATA TX Operator’s Guide/Tech Ref Manual2.3 System ComponentsThis section will provide more details about each the components of a STRATA TX System:•STRATA TXU • STRATA TCU •STRATA ACU• STRATA Remote Control PanelsFor details on connections between the STRATA TX System components, refer to the “Installation” chapter (part of the STRATA TX Technical Reference Manual only).2.3.1 STRATA TXUThe TXU (See Figure 2-6) always contains an IF/RF module that accepts either a 70 MHz COFDM, FMT IF, or external 70 MHz input signal and up-converts these signals to the required RF band. The RF frequency synthesizer circuit included in the IF/RF unit, in conjunction with the command and control power supply module, provides the means to channelize RF video and audio signals in the TX System RF band.The TXU, with either an analog (FMT) or digital (MPEG/COFDM) module, is integrated in the same housing as the HPU components. This provides the ability to incorporate high RF power output (12 watts of saturated RF power) into a single analog or digital transmitter assembly.Standard U.S. FCC band plans, as well as customer-created channel plans, may be customized using the STRATA TX Configurator software.Figure 2-6: STRATA TXUAs noted previously, the TXU may also include either an MPEG/CODFM or FMT module (but not both), in which case the TXU serves as a stand-alone digital or analog video microwave transmission system. 2.3.2 STRATA TCUThe TCU (See Figure 2-7 on page 2-8) may contain either analog or digital or both analog and digital video modulation modules. Where an application might initially employ only analog video transmission but expects to migrate to dual, switchable, analog and digital operation, the TCU may be upgraded to add the MPEG/COFDM module to add this capability.
Product Description 2-8STRATA TX Operator’s Guide/Tech Ref ManualFigure 2-7: STRATA TCUWhere only digital or analog video transmission is desired, the MPEG/COFDM or FMT modules may be installed in a TXU, thereby eliminating the need for a TCU. The STRATA TX design does not permit splitting digital and analog video modulator modules between a TXU and a TCU. A TCU may also consist of a stand-alone configuration whereby either or both MPEG/COFDM and FMT modules may be used independent of the TXU. This configuration permits use of a TCU equipped with analog and/or digital video modulation modules for a variety of signal input and output configurations, including a digital option using NTSC or PAL composite video input and ASI (digital) signal output. 2.3.3 STRATA ACUFor fixed or portable deployment applications, the STRATA TX System may be powered by the optional AC to DC Converter (ACU). See Figure 2-8. Figure 2-8: AC to DC ConverterThe ACU installs as part of an integrated stack for either tripod or fixed applications. The ACU may also be used to power the TXU or TCU only when a TXU and TCU are not co-located. In this case, the TXU would receive DC power from the TCU or the TCU would receive DC power from the TXU superimposed on the coaxial cable connected between the units.In standalone TXU or TCU operations, the optional ACU may be used to supply DC power directly to the applicable unit. In the case where a TXU and a TCU are co-located, it is recommended that both the TXU and TCU be powered directly from the ACU in lieu of supplying DC power from the TCU to the TXU or from the TXU to the TCU via the coaxial cable connected between the units.2.3.4 STRATA Remote Control PanelsFor mobile or airborne operations, two Remote Control Panel models are currently available.

Routine Operation 3-10STRATA TX Operator’s Guide/Tech Ref Manual3.3 Preparing for OperationEach installation or deployment will have its own specific tasks according to the application and the installed hardware. 3.3.1 Mobile InstallationFor mobile applications such as aircraft or vehicle, the STRATA TX System is usually mounted in a bulkhead or compartment using an MRC Fixed Mounting Bracket. See Figure 3-5. Mounting brackets are available to mount from one to three units. Figure 3-5: Fixed Mounting BracketThe cabling is permanently installed and power comes from aircraft (or vehicle) power.3.3.2 Portable DeploymentFor situations where you need to mount a STRATA TX System and its Fixed Mounting Bracket to an MRC tripod, MRC also offers a Quick Release. See Figure 3-6.For situations where you are mounting to another type of tripod that doesn’t directly accept the Quick Release, consult with MRC or your tripod manufacturer. MRC has Dovetail Adapter Plates that will convert some types of tripods to accept the Quick Release.Figure 3-6: Fixed Mounting Bracket on TripodNote The versatility of the Quick Release Mount and mating Dovetail Adapter Plate allows the Dovetail Adapter Plate to be attached to the bottom of the Universal Mounting Bracket and the Quick Release Mount to be attached to a non-MRC tripod, or vice versa.For optional methods of attaching your STRATA TX System to a non-MRC tripod, refer to the “Installation” Chapter on page 6-1 (part of the STRATA TX System Technical Reference Manual only) For portable applications where the STRATA TX System will be moved from place to place and set up each time, the system will Fixed Mounting BracketQuick ReleaseMRC Tripod (Typical)
Routine Operation 3-11STRATA TX Operator’s Guide/Tech Ref Manualusually be mounted in an MRC Universal Mounting Bracket. The Universal Mounting Bracket will then be attached to a Quick Release for easy mounting on an MRC tripod. See Figure 3-7. Universal Mounting Brackets are required for each unit in the STRATA TX System, i.e., TXU, TCU, and an optional ACU. For applications using multiple units such as a TXU, TCU, and an ACU, a Mounting Plate is also used to provide additional stiffness. The Mounting Plate typically remains attached between the Universal Mounting Bracket and the Quick Release. The cabling between TX System units is also typically left in place. The power, antenna and audio/video connections are usually removed at the end of each deployment. For portable deployment situations where you are mounting to another type of tripod that doesn’t directly accept the Quick Release, consult with MRC or your tripod manufacturer. MRC has Dovetail Adapter Plates that will convert some types of tripods to accept the Quick Release.Note The procedures and illustrations contained in the following paragraph are typical, reflecting use of an MRC tripod.Mounting to the Tripod Following are the general steps to mount a STRATA TX System to an MRC Tripod. These steps assume the TX System is already assembled into its Universal Mounting Bracket(s), and that the Mounting Plate and Quick Release are attached. Figure 3-7: Universal Mounting Bracket on Tripod 1. Attach the TX System to the Tripod using the Quick Release as shown in Figure 3-8 on page 3-12. 2. Attach the antenna to the TXU using the Antenna Lock Plate, or connect a coaxial cable from the TXU to the antenna. See Figure 3-9 on page 3-12.

Routine Operation 3-13STRATA TX Operator’s Guide/Tech Ref ManualSuperimposing DC Power In this configuration, DC power is superimposed with the IF signals between units and there is no manual control of DC power from the TCU. The DC power is superimposed on the coaxial cable between the TCU and the TXU.To turn DC power on and off, the operator uses the TCU and TXU front panel PWR switches and either the TCU or TXU control switch and alphanumeric display menus. The TXU DC ON COAX switch must be set to ON.Superimposing DC Power with Manual Control In this configuration, DC power superimposed on the IF signals between the units is manually controlled. The operator can manually turn DC power on or off to the TXU from the TCU or to the TCU from the TXU using DC ON COAX switches and TCU or TXU front panel control switches and alphanumeric display menus.The DC ON COAX switches provide the manual control and must be set to ON to allow application of DC power to the TXU , and TCU using the control switches and alphanumeric display menus.Powering STRATA TX Systems The method you use to power up your STRATA TX System will vary, depending upon the following:• The model of your STRATA TX System, whether or not you have DC power manual override control. • The transmitter configuration, whether you are using a single TCU, a single TXU, or a TCU and TXU • Whether the TCU and TXU are to be co-located or physically separated over some distance.• Whether your STRATA TX System contains the optional AC to DC Power Converter (ACU). 3.3.4 Single TCU Power Up and Power DownIf your STRATA TX System consists of a single TCU, perform the following steps:CAUTION To avoid possible damage, turn off DC Power on the coax before connecting any test equipment.Power Up 1.

Following are some points to make this easier.Main Screen The Main Screen is your starting point for navigating through the Monitor and Control option screens. The Main screen provides the current values of the Preset selected and the selected Preset output power level. When the STRATA TX System completes its power-up sequence, it will display the Main Screen. A typical Main screen is shown in Figure 3-17.Figure 3-17: Typical STRATA TX Main Screen Accessing the Main Screen You can access the Main screen at any time by scrolling to the end of the screens you are viewing (either Monitor or Control). Your next click of the control switch will bring up the Main screen. Accessing the Monitor Screen You can access the Monitor option screens at any time by turning the control switch clockwise (cw). Accessing the Control Screen You can access the Control option screens at any time by turning the control switch counter-clockwise (ccw). Preset 3 . WCurrently Selected PresetOutput Power LevelDefault to Main Screen If you do not turn or push the control switch for a period of about 7 seconds, the display will default to the Main screen.If you turn the control switch within those 7 seconds, you will continue scrolling within that set of screens (Monitor or Control).Unit vs.System Control If you’re using a standalone TXU or TCU, the menus and options that appear on the display will be based on the hardware option(s) installed in that individual unit. When you connect your TCU and TXU, the two units automatically detect what hardware is installed in each unit, and automatically configure the menus and options to match the installed hardware. The connected STRATA TX System then allows you to control the entire system from either the TXU or the TCU front panel.3.5 TXU and/or TCU Monitoring Operations The STRATA TX System Presets are set to six possible modes of operation, based on the options contained in your TXU and/or TCU. These operating modes are established using the STRATA TX Configuration Utility software. The operating mode options available via the Configuration Utility software are as follows:• MPEG Only ASI Out (MPEG Output mode) (Standalone TCU Operation Only)• External 70MHz IF In (Ext IF Input mode)• MPEG/COFDM IF Out (COFDM - IF mode)• COFDM Only - ASI In (COFDM ASI In mode)• Analog IF Output (Analog - IF mode)• DVB-S (Satellite) (DVB-S mode) (Standalone TCU

Note When the TCU and TXU are mounted in separate locations, it is recommended that DC input power be connected to the TXU. Since either unit may be powered from the other unit via DC power superimposed on the coaxial cable between the units, DC input power may therefore be applied to either the TXU or the TCU.If your TXU and TCU configurations contain DC ON COAX switches mounted on the units, these switches must be set to ON in addition to controlling DC power superimposed on the coaxial cable from the TXU to the TCU or from the TCU to the TXU. To apply DC power from the TXU to the TCU superimposed on the coaxial cable between the two units, perform the following steps.Notes This procedure must only be performed on STRATA TX Systems where the TXU and TCU are physically mounted in separate locations.This procedure may be performed using either the TXU or TCU control switch and display.Apply DC Power on Coax 1. Verify the STRATA TX System is connected and powered up. See ”Powering the STRATA TX System” on page 3-12.2. Observe the Main screen is displayed. See Figure 3-32.Figure 3-32: Main Screen Note If your TCU does not contain a DC ON COAX switch, go to step 4.3. Turn the recessed DC ON COAX switch on the front panel of the TCU until the screw slot points to OFF.4. Turn the recessed DC ON COAX switch on the front panel of the TXU until the screw slot points to OFF.5. Turn the control switch ccw until the display reads 75 Ohm Coax. See Figure 3-33.Preset 3 . W
