BZ5MXD30U Application for FCC Certification 30 Watt Digital Television Translator Operational Description: This application requests certification for a 30 Watt Digital Television Translator. The intended use of this digital translator is to rebroadcast a television relay station or other legal source of ATSC digital television signal. The MXD30U is a solid state digital regenerative translator designed to receive over-the- air ATSC signals, converting the RF signal to baseband digital format, processing the signal to eliminate noise, and then re-modulating, converting to the new broadcast channel, amplifying and filtering the signal before it is applied to the transmit antenna. The receive section of the translator and the output modulation format conform with FCC Part 73.682(d), ATSC Digital Television Standards. The MXD30U consists of four components: a 1RU RegenT Transcoder unit which receives processes and remodulates the signal, a 5 RU 30W RF amplifier,a 5RU Power supply for said amplifer and an output filter. The power supply and amplifier employ integral cooling fans. Depending on the specific application of the translator, the filter is either a simple mask type filter of a stringent mask type filter. With the exception of the output emission mask response, all other performance parameters as detailed in this report are identical for either type of filter. The filter along with additional filtering within the amplifier provide more than 85dB of attenuation within the GPS Frequency bands (1164-1240 MHz and 1559-1610 MHz). Note that since these products are frequency agile in that they can be field tuned for different channels within the UHF television band, each unit has this filtering included, regardless of the channel. Wiring, shielding and construction are in accordance with accepted principles of good engineering practice. The translator’s construction is such that all hazardous components are enclosed or protected against accidental contact by operating personnel.

BZ5MXD30U Application for FCC Certification Regenerative Digital Television Translator Parts List and Tune-up Procedure: The following is the procedure for changing the channel of the MXD30U translator. Since the amplifier is broadband, channel change involves retuning of the output filter and recalibration of the output meter. The amplifier meter was calibrated to read 100% (top scale) at full power and at the channel specified when the transmitter was tested at the factory. If the amplifier is to operate at a channel other than that of the factory test channel, the metering is going to require re-calibration. The power meter setting is a channel dependent calibration. 1. Connect the transmitter output to a 50 ohm dummy load or the antenna. The transmitter uses a 50Ω type N connector for its output. An inline wattmeter with a selection of detector elements should be used for measurements. 2. Connect the 115VAC mains input. This AC circuit should be rated for 15 amperes, and should be supplied through a slow-tripping breaker or time delay fuse. Generally, a breaker that is rated for across-the-line motor starting will be found to be satisfactory. Also, connect the power cable that connects the power supply to the amplifier. This is the nine-wire cable supplied with the amplifier. 3. Switch `ON’ the power supply circuit breaker. Depress the power supply `ON’ push button switch. The two LEDs marked INTRLK and TEMP should be lighted, and the amplifier should be operating and the cooling fans on both the power supply and the amplifier should be running. 4. The amplifier is equipped with AGC and VSWR protections which have been factory set. To set the correct level out of the channel processor or exciter, switch OFF the amplifier AGC (switch down) then adjust the Transcoder level control so that the output of the amplifier is 110%. Switch ON the AGC and front panel meter should read 100%. If not, adjust the front panel pot labeled AGC LEVEL for 100% indication. The output filter must be retuned as per the frequency response sweeps attached (note: two different tunings depending on the type of filter used): BZ5MXD30U Application for FCC Certification Regenerative Digital Television Translator Parts List and Tune-up Procedure Simple Mask Filter: Bandpass Response BZ5MXD30U Application for FCC Certification Regenerative Digital Television Translator Parts List and Tune-up Procedure Simple Mask Filter: Return loss BZ5MXD30U Application for FCC Certification Regenerative Digital Television Translator Parts List and Tune-up Procedure Stringent Mask Filter: In band Response BZ5MXD30U Application for FCC Certification Regenerative Digital Television Translator Parts List and Tune-up Procedure Stringent Mask Filter: Return loss LineTpComponentDescriptionIDQtyUMTotal 11940D2206A1ASSEMBLY DRAWING R-30EA0 110541D1452P1FRONT PANEL R-41EA1 112541D1483P1FRAME (CHASSIS) R-41EA1 114541D1444P1REAR PANEL R-21EA1 115541D1504P1TOP COVER R-01EA1 120140D2208G1 HEATSINK ASSY 100W AMP UHF R - 71EA1 21940D2208ASSEMBLY DRAWING R-40EA0 210541D1475P1HEATSINK R-21EA1 211121B2230G2AMP RF UHF NO CONN.

BZ5MXD30U Application for FCC Certification Regenerative Digital Television Translator Power Measurements The translator’s power meter circuit uses a detected sample from a coupler on the output. An averaging detector circuit provides the DC level to drive the translator’s output level meter. The translator was connected to a test load through a calibrated directional coupler. The spectrum analyzer’s “Channel Power” function was used to measure the average power level of the signal as sampled through the directional coupler. (see Fig.) Measured power: 1.3dBm Coupling loss: 43.5dB Power: 44.8dBm Power = 30.2 Watts
