System Overview The LU6000AL (1306589) is made up of the (8) trays listed in Table 8-1. Table 8-1. LU6000AL Major Trays and Assemblies MAJOR ASSEMBLY DESIGNATOR TRAY/ASSEMBLY NAME DRAWING NUMBER A1 UHF Exciter 1303268 A2, A3, A4, A5, A6, A7 External Amplifier Assembly 1303828 The (A2) UHF Exciter can operate using a 45.75 MHz IF carrier from either the (A1) Receiver tray’s output, or that from a Modulator tray. Both of these carriers must be diplexed with a 41.25 MHz aural carrier, at an A/V ratio not to exceed –10dB. Axcera-LU6000AL FCC Type Acceptance Report Operational Description October 2005 8-3 8.4.1 Exciter Tray (Driver)/External Amplifier Tray The input to the Exciter Tray is a modulated Internally Diplexed IF signal. This signal is connected to the input of the IF Processor Module. The output of the Exciter Tray (driver) drives the input to the External Amplifier Tray. 8.4.2.1 Receiver Module (Driver) The UHF/VHF Receiver converts a low level RF input signal to an IF frequency of 44 MHz, filters off any unwanted out of band energy, and normalizes the level so that it can be applied to the IF processor assembly. It consists of three boards. The RF input is applied first to the UHF/VHF preamplifier board, which filters off out of channel energy and amplifies the input signal. The RF output is applied to the Mixer/PLL board, which converts the signal down to an IF frequency of 44 MHz. The IF output is applied to the IF ALC board, which amplifies the signal…

Axcera-LU6000AL FCC Type Acceptance Report Parts List/Tune-up Info October 2005 7-1 7. PARTS LIST/TUNE-UP INFO 7.1 Parts List The translator, can be subdivided as follows: Exciter Tray: • Receiver Module • IF Processor Module • L.O. / Upconverter Module • Control & Monitoring / Power Supply Module • Power Amplifier Module External Amplifier Trays: • 4-Way Splitter (Qty of 6) • Power Amplifier Module (Qty of 24) • Power Supply Module (Qty of 12) • 4-Way Combiner (Qty of 6) 7.2 Tune-up Information The LU6000AL translator was aligned at the factory and should not require additional alignments to achieve normal operation. The UHF/VHF Receiver converts a low level RF input signal to an IF frequency of 44 MHz, filters off any unwanted out of band energy, and normalizes the level so that it can be applied to the IF processor assembly. It consists of three boards. The RF input is applied first to the UHF/VHF preamplifier board, which filters off out of channel energy and amplifies the input signal. The RF output is applied to the Mixer/PLL board, which converts the signal down to an IF frequency of 44 MHz. The IF output is applied to the IF ALC board, which amplifies the signal, filters off any unwanted out of band energy and controls its own IF gain to make sure that the IF output level is constant. There is also a provision to apply +12V to the RF input center conductor to power an external preamplifier. 7.2.1 Exciter/Amplifier Chassis Assembly The exciter/amplifier chassis assembly operates using an external IF input from an external receiver tray. The IF source connects to J6, the modulated IF Input jack, on the rear of the chassis assembly, which is cabled to the IF Processor Module. On the LCD Display, located on the Controller/Power Supply Module, push the button to switch the translator to Operate. The setup of the RF output includes adjustments to the drive level of the Power Amplifier, the adjustment of the linearity and phase predistortion to compensate for any nonlinear response of the Power Amplifier on the front panel of the IF Processor module. Verify that all red LEDs located on the IF Processor front panel are extinguished. The following details the meaning of each LED when illuminated: Axcera-LU6000AL FCC Type Acceptance Report Parts List/Tune-up Info October 2005 7-2 • DS1 (input fault) – Indicates that either abnormally low or no IF is present at the input of the 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 translator to Standby. The ALC is muted when the translator 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 translator 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 translator 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 translator to 100%. 7.2.2 Linearity Correction Adjustment As shipped, the exciter was preset to include amplitude and phase pre-distortion. The pre- distortion was adjusted to approximately compensate the corresponding non-linear distortions of the Power Amplifier. NOTE: On the IF processor board inside the module the correction enable/disable jumper W12 on J30 will be in the Enable position, on pins 2 & 3. Set up a spectrum analyzer with 100 kHz resolution bandwidth and 100 kHz video bandwidth to monitor the intermodulation products of the RF output signal of the Power Amplifier. There are three Linearity Corrector stage adjustments located on the front panel of the IF Processor Module. The adjustments are threshold settings that are adjusted as needed to correct for any amplitude or phase intermod problems. Adjust the top linearity correction adjustment R211 threshold cut in for the in phase amplitude distortion pre- correction that is needed. Next adjust the middle linearity correction adjustment R216 threshold cut in also for the in phase amplitude distortion pre-correction that is needed. Finally adjust the bottom linearity correction adjustment R231 threshold cut in for the quadrature phase distortion pre-correction that is needed. The above pots are adjusted for the greatest separation between the peak visual carrier and the intermod products. 7.2.3 Frequency Response Delay Equalization Adjustment The procedure for performing a frequency response delay equalization adjustment for the translator is described in the following steps: The center frequency for the first stage is 45 MHz. Adjust R103, the top frequency response equalizer pot, located on the front panel of the IF Processor Module, for the best depth of frequency response correction at 45 MHz. The center frequency for the second stage is 43.5 MHz. Adjust R106, the middle Axcera-LU6000AL FCC Type Acceptance Report Parts List/Tune-up Info October 2005 7-3 frequency response equalizer pot, located on the front panel of the IF Processor Module, for the best depth of frequency response correction at 43.5 MHz. The center frequency for the second stage is 42 MHz. Adjust R274, the bottom frequency response equalizer pot, located on the front panel of the IF Processor Module, for the best depth of frequency response correction at 42 MHz. After the three delay attenuation equalizers have been adjusted, fine tune, as needed, fo…
