Axcera-LHV100AT FCC Type Acceptance Report Parts List/Tune-up Info August 2006 7-1 7. PARTS LIST/TUNE-UP INFO 7.1 Parts List The transmitter, can be subdivided as follows: Transmitter Tray: ƒ Modulator Module ƒ IF Processor Module ƒ L.O. / Upconverter Module ƒ Control & Monitoring / Power Supply Module ƒ Power Amplifier Module 7.2 Tune-up Information The LHV100AT transmitter was aligned at the factory and should not require additional alignments to achieve normal operation. 7.2.1 Transmitter Chassis Assembly This transmitter takes the baseband audio and video inputs or, if the (Optional) 4.5-MHz composite input kit is purchased, either a single composite video + 4.5-MHz input or separate baseband video and audio inputs, and converts them to the desired VHF On Channel RF Output at the systems output power level. 7.2.2 Modulator Module Assembly Note: Not present in Translator systems. The Modulator Assembly has adjustments for video levels and audio modulation levels, and other related parameters. Connect an NTSC base-band video test signal input (1 Vpk-pk) to the transmitter video input jack J7 on the rear of the tray. Jacks J7 and J17 are loop-through connected; the J17 jack can be used as a video source for another transmitter. Connect a base-band audio input (+10 dBm) to the balanced audio input terminal block TB02-1 [+], TB02-2 [-], and TB02-3 [ground] or, if stereo/composite audio is provided, connect it to BNC jack J3, the composite audio input jack. Verify that all LEDs located on the front panel of the Modulator are Green. The following details the meaning of each LED: AURAL UNLOCK (DS5) – Red Indicates that 4.5 MHz Aural IF is unlocked from the 45.75 MHz visual IF. VISUAL UNLOCK (DS6) – Red Indicates that the 45.75 MHz visual IF is unlocked from the 10 MHz reference. AUDIO OVER DEVIATION (DS4) – Red Indicates that the input Audio level is too high. VIDEO LOSS (DS1) – Red Indicates that the input Video level is too low. OVER MODULATION (DS3) – Red Indicates that the input Video level is too high. Axcera-LHV100AT FCC Type Acceptance Report Parts List/Tune-up Info August 2006 7-2 ALTERNATE IF (DS7) – Red Indicates that an external 45.75 MHz IF is not present to the modulator. 10 MHz PRESENT (DS2) – Red Indicates that an external 10 MHz reference in not present to the modulator. Look at the front panel LCD meter on the Control/Power Supply Module Assembly. Set the LCD screen to the Modulator Details video output level screen, the screen indicates active video from 0 to 1 Vpk-pk. The normal video input level is 1 Vpk-pk on the front panel screen. If this reading is not at the proper level, the overall video level can be changed by adjusting the VIDEO LEVEL control R42 on the front panel of the Modulator to the 1 Vpk- pk level on the front panel screen. Switch the LCD display to the Modulator Details screen that indicates the AUDIO DEVIATION (modulation level) of the signal from 0 to 100 kHz. MONO SET UP: The modulator was factory set for a ±25-kHz deviation with a mono, balanced, audio input of +10 dBm. If the reading is not at the correct level, adjust the MONO Audio Gain pot R110, located on the front panel of the modulator, as necessary, to attain the ±25-kHz deviation on the front panel screen. STEREO SET UP: The modulator was factory set for a ±75-kHz deviation with a stereo, composite, audio input of 1 Vpk-pk. If this reading is not correct, adjust the STEREO Audio Gain pot R132, located on the front panel of the modulator, as necessary, for the ±75-kHz deviation. SECONDARY AUDIO SET UP: NOTE: Remove any stereo or mono audio modulation input to the transmitter during the set up of the secondary audio. The modulator was factory set for a ±15-kHz deviation with a secondary audio input of 1 Vpk-pk. If this reading is not correct, adjust the SAP/PRO Audio Gain pot R150, located on the front panel of the modulator, as necessary, for the ±15-kHz deviation. 7.2.3 If Processor Module Assembly Verify that all red LEDs located on the IF Processor front panel are extinguished. The following details the meaning of each LED when illuminated: • DS1 (input fault) – Indicates that either abnormally low or no visual IF is present at the input of the IF Processor module. • DS2 (ALC fault) – Indicates that the ALC circuit is unable to maintain the signal level requested by the ALC reference. This is normally due to excessive attenuation in the linearity signal path or the IF phase corrector signal path, or that switch SW1 is in the Manual ALC Gain position. • DS4 (Mute) – Indicates that a Mute command is present to the system. Switch the transmitter to Standby. The ALC is muted when the transmitter is in Standby. Switch the transmitter to Operate. Verify that all LEDs located on the front panel of the visual Upconverter are Green. The following details the meaning of each LED: PLL 1 Fault (DS1) - Displays the status of the 1 GHz PLL, Green locked or Red unlocked Axcera-LHV100AT FCC Type Acceptance Report Parts List/Tune-up Info August 2006 7-3 PLL 2 Fault (DS2) - Displays status of the 1.1-1.9 GHz PLL, Green locked or Red unlocked AGC Fault (DS7) – NOT USED IN THIS CONFIGURATION.

Stainless Steel mounting hardware is recommended, grade 18-8 or better. A lock washer of same material should also be used. 2Ensure mounting surface is flat to better than 0.003” / “ 3Use a thin layer of thermal compound on the backside of the PA - no more than 0.001” - 0.002” thickness! 4Torque all screws to 10-12 in-lbs Considerations for Mechanical Mounting: •Considerations for proper thermal design include •Total power dissipated = Total DC Power Consumed x (1-Efficiency) •Ambient Airflow •Thermal Resistance of Heat Sink For this PA, typical DC efficiency is 30%. 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.
