System Overview The LHV60ATD is made up of the trays listed in Table 8-1. Table 8-1. LHV60ATD Major Trays and Assemblies MAJOR ASSEMBLY DESIGNATOR TRAY/ASSEMBLY NAME A1 Axciter Modulator Tray A2 VHF HB Exciter Assembly 8.4.1 Exciter Tray 8.4.1.1 Axciter – Enternal Digital Modulator The Axciter modulator is an ATSC compliant 8 VSB modulator that is used externally with the Innovator LX Driver chassis assembly. The Axciter modulator also accepts a SMPTE-310 MPEG data stream input and outputs a 6 MHz wide IF output centered at 44 MHz. All of the functions of the Axciter modulator are controlled from the front panel pushbuttons. 8.4.1.2 Axciter Upconverter Module The 44 MHz IF input, -6 dBm in level, to the upconverter module assembly is applied through the backplane board from the modulated IF input jack located on the rear of the HX or LX exciter/driver chassis assembly. The 44 MHz IF input to the upconverter/downconverter tray connects through J5, the IF input jack located on the rear panel. The signal connects to the First Conversion board and is converted to a second IF of 1044 MHz by an image rejection mixer located on the First Conversion board. A filter selects the appropriate conversion product, which is then amplified to a level of approximately –8 dBm. The 1 GHz LO frequency is generated externally by the Axciter modulator and is applied to a high pass and low pass filter designed to eliminate any other interfering signals that might be coupled into the 1 GHz LO. The LO is applied to an ALC circuit that maintains the LO level to each mixer of +13 dBm over a wide range of 1 GHz LO input levels. The LO sample is also sent to the Downconverter board inside the tray or to the external Downconverter module for its use. This second IF signal is then applied to a second mixer mounted on the Final Conversion board that converts it back to a broadcast channel (2-69) by an LO that operates in 1.0 MHz steps between 1.1-1.9 GHz depending on the channel selected. The LO frequency equals the Channel center frequency plus 1044 MHz. (As an example CH: 14: Center Frequency is 473.00 MHz therefore LO2 is 473 + 1044, which equals 1517.00 MHz.) Axcera-LHV60ATD FCC Equipment Authorization Report Operational Description December 2007 8-3 The output of the mixer is applied to a 900 MHz Low pass filter to remove unwanted conversion products. The resulting signal is amplified and wired to a Pin diode attenuator and then connected to the output of the Upconverter/Downconverter Tray or the output of the Upconverter Module. This pin diode attenuator adjusts the gain of the tray or module and is controlled by an Automatic Gain Control circuit, which maintains a constant power out of the upconverter, and also the transmitter, that connects to the power amplifier module. Processor board detects an Input Signal fault it automatically Mutes the transmitter. The system controller does not Mute on an IF Processor Input fault. The Axciter upconverter module has no need for periodic alignment. 8.4.1.3 Axciter Downconverter Module A sample of the transmitter’s RF output is applied to the downconverter board, mounted on the downconverter module, at a nominal input level of –6 dBm. The signal is attenuated by a 10 dB pad, and then converted to an IF of 1044 MHz by mixer U1. A sample of the upconversion LO from the L-Band PLL Board mounted in the upconv…

Axcera-LHV60ATD FCC Type Acceptance Report Parts List/Tune-up Info December 2007 7-1 7. PARTS LIST/TUNE-UP INFO 7.1 Parts List The transmitter, can be subdivided as follows: ƒ External Axciter Digital Modulator Tray Exciter Tray, consisting of: ƒ Axciter Upconverter ƒ Axciter Downconverter ƒ Control & Monitoring / Power Supply Module ƒ Power Amplifier Module 7.2 Tune-up Information The LHV60ATD transmitter was aligned at the factory and should not require additional alignments to achieve normal operation. 7.2.1 Exciter Assembly This transmitter takes the IF from the digital modulator and converts the signal to the desired High-Band VHF On Channel RF Output at the systems output power level. Switch On the main AC for the system and the individual circuit breakers on each assembly. Check that AC is present to the system. Check that the RF output of the post-filter coupler assembly is terminated into a dummy load of at least the rated output of the system or connected to the antenna for your system. While performing the alignment, refer to the Test Data Sheet for the transmitter and compare the final readings from the factory with the readings on each of the modules. The readings should be very similar. If a reading is way off, the problem is likely to be in that module. This transmitter operates using a SMPTE 310 input that connects to J27, the MPEG Input Jack, located on the rear of the Axciter Modulator Tray. Check that the MPEG input is present. If used, check that the 10 MHz input from the GPS is connected to J9 on the Axciter Modulator. The check of and the setup of the drive level and output power of the transmitter are completed using the LCD Display on the control/power supply module. In the Transmitter Set-Up menu and the Power Control Screen, set the output power to 100% or the drive level needed to attain the desired output power of the transmitter. The transmitter must be in the Manual Gain position when readjusting the Forward Power. The adjustment of the linearity and phase pre-distortion to compensate for any nonlinear response of the Power Amplifiers are controlled within the Axciter Modulator Tray. Axcera-LHV60ATD FCC Type Acceptance Report Parts List/Tune-up Info December 2007 7-2 7.2.1.1 Upconverter Downconverter Adjustment On the Axciter Modulator, activate the Upconverter Main screen by selecting Upconverter, using the button next to Upconverter on the right side of the Axciter Main Screen. Activate the Downconverter Output Gain by pushing 2 on the key board entry pad. Monitor the DTVision Linear Display by pushing the button next to the DTVision Linear display on the right side of the Axciter Main Screen. At the bottom of the DTVision linear screen, locate the reading next to RMS. If this reading is between –10 dBm and 0 dBm no adjustment is needed. If it is not, adjust the “Downconverter Gain”, then view the RMS value until it is within the –10 dBm to 0 dBm range. 7.2.1.2 Forward Power Calibration Check that the transmitter is at 100% output power, as shown on the LCD display on the Driver/Amplifier in the Set Up menus. Measure with a VOM, TP31-14, Red, and TP31-12, Black, on the terminal block TP31, located on the rear chassis of the Driver/Amplifier Chassis Assembly. Adjust R9, Forward Calibration Adjustment, on the Dual Peak Detector Board (1159965) for a reading of .8VDC on the VOM. Locate the Forward Power Adjust screen on the Driver/Amplifier LCD display in the Set Up menus and adjust the up or down arrow as needed to achieve 100 % output power. This completes the forward power set up. 7.2.1.3 Reflected Power Calibration Switch the transmitter to Standby. Remove the connector that is on Jack J2, on the Dual Peak Detector Board (1159965), and replace with the connector now on J1, also inserting a 10 dB pad in series. Switch the transmitter to operate. Then adjust R10, Reflected Calibration Adjustment, on the dual peak detector board (1159965) for a .32VDC reading, at TB31-13 and TB31-12 return, on the terminal block TB31 mounted on the rear of exciter/driver chassis assembly. Switch the transmitter to Standby. Move the connector back to J1 while removing the 10 dB pad. Replace the original connector onto J2. Axcera-LHV60ATD FCC Type Acceptance Report Parts List/Tune-up Info December 2007 7-3 7.2.2 Axciter Digital Modulator The Digital Modulator has adjustments for modulation levels, and other related parameters. Switch the transmitter to Standby. The ALC is muted when the transmitter is in Standby. To monitor the ALC, preset R3, manual gain-adjust, on the front panel of the Upconverter module, fully CCW. Move switch SW1, Auto/Man AGC, on the front panel of the Upconverter module, to the Manual position. Place the transmitter in Operate. Adjust the ALC GAIN pot on the front panel of the IF Processor to obtain +0.8 VDC on the LCD Display on the Controller/Power Supply in the ALC screen. Move the MAN/AUTO ALC switch back to Auto, which is the normal operating position. To adjust the AGC Cutback setting, raise the output power of the transmitter to 110%. Adjust R2, AGC Cutback, located on the front panel, CCW until the LED DS1, AGC Cutback, just starts to flash. Return the output power of the transmitter to 100%. 7.2.3 Bandpass Filter Assembly The Bandpass Filter Assembly is tuned to reject unwanted distortion products generated when the signals are diplexed and also during the amplification process. The Bandpass Filter is factory tuned to the proper bandwidth and should not need tuned. If you think tuning is needed consult Axcera Field Support Department before beginning the adjustment. The Transmitter is ready for normal operation. This completes the detailed alignment procedures for the transmitter.

At 25W Pk power output, 15W Average, +28.0V DC operation, 84 total watts are consumed, which leaves 70W dissipated power. If we assume an input air temperature of +25°C, and a maximum desired baseplate temperature of 55°C, this leaves a temperature differential between baseplate and ambient air of 30°C. The desired thermal resistance for heatsink mounting surface to air is therefore 30°C/74W = 0.4°C/W. Since the baseplate is aluminum, it is important to find a heat sink that it sized at least as big as the outline of the PA which can give this thermal resistance. For example, a 100mm x 54mm heat sink with serrated fins, 70mm in length, (20 fins across 127mm dimension) with an air velocity of 4 m / s exceeds this value.
