System Overview The LU3000ATD is made up of the trays listed in Table 8-1. Table 8-1. LU3000ATD Major Trays and Assemblies MAJOR ASSEMBLY DESIGNATOR TRAY/ASSEMBLY NAME A1 UHF Exciter Assembly A2, A3, A4, A5, A6, A7 External Amplifier Assembly A8 Optional Axciter Modulator 8.4.1 Exciter Tray/External Amplifier Tray The output of the Exciter Tray (driver) drives the input to the External Amplifier Tray. 8.4.1.1 DM8 – Internal Digital Modulator Module (Exciter) The DM8 modulator is an ATSC compliant 8 VSB modulator that slides into the left most slot in the Innovator LX Driver chassis assembly. The DM8 modulator accepts a SMPTE- 310 MPEG data stream input and outputs a 6 MHz wide IF output centered at 44 MHz with a pilot carrier at 46.69 MHz. The DM8 modulator provides linear and nonlinear correction capability for the transmission path as well as internal test sources that are used during initial transmitter installation. All of the functions of the DM8 modulator are controlled from the LX Controller LCD display and pushbuttons. 8.4.1.2 Axciter – Enternal Digital Modulator Module (Exciter) The Axciter modulator is an ATSC compliant 8 VSB modulator that is used externally with the Innovator LX Driver chassis assembly. Like the DM8 modulator, 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. 8.4.1.3 IF Processor Module – Used with DM8 Only (Exciter) The IF Processor Assembly contains the IF Processor Board (1301977). The IF Processor provides pre-correction to ensure broadcast quality output signal. The pre-correction consists of amplitude linearity correction, Incidental Carrier Phase Modulation (ICPM) correction and frequency response correction. The IF Processor module is configured either for an analog or digital system. Pin 13C of the IF Processor module is grounded in analog systems and left not connected in digital systems. An IF Processor Interlock signal is used to report the presence of the IF Axcera-LU3000ATD FCC Type Acceptance Report Operational Description June 2007 8-3 Processor module to the Control Monitoring board. If the IF Processor interlock signal is not present, the transmitter/Exciter Driver RF output is Muted (turned off). If an analog IF Processor module is installed and the Modulation Present signal is not true, the transmitter / Exciter Driver output is Muted (turned off). The Control & Monitoring/Power Supply module uses the IF Processor module for System output power control. Through the front panel display or a remote interface, an operator can set the transmitter's RF output power. The range of RF power adjustment is between 0% (full off) and 105% (full power plus). A front panel IF Processor module potentiometer sets the upper limit of RF power at 120%. The system's Control Monitoring board compares the RF Power Monitoring module RF power level with the desired level and uses the IF Power Control PWM line to correct for errors. In digital systems, a digital level control (DLC) voltage is generated on the IF Processor module and sent to the digital modulator. RF power control is implemented by changing the DLC voltage provided to the digital modulator. The 'RF High' potentiometer sets the upper adjusted range of RF control circuit output to 120%. The IF Processor mod…

Axcera-LU3000ATD FCC Type Acceptance Report Parts List/Tune-up Info June 2007 7-1 7. PARTS LIST/TUNE-UP INFO 7.1 Parts List The transmitter, can be subdivided as follows: Exciter Tray: ƒ DM8 – Internal Digital Modulator Module or External Axciter Digital Modulator Tray ƒ IF Processor Module (Used only with DM8 Modulator) ƒ VHF/UHF Upconverter Module (Used only with DM8 Modulator) or Axciter Upconverter (Used only with Axciter Modulator Tray) ƒ Axciter Downconverter (Used only with Axciter Modulator Tray) ƒ Control & Monitoring / Power Supply Module ƒ Power Amplifier Module ƒ External Amplifier Trays (Qty of 6): ƒ 4-Way Splitter (Qty of 6) ƒ Power Amplifier Module (Qty of 24) ƒ Power Supply Module (Qty of 12) ƒ 4-Way Combiner (Qty of 6) 7.2 Tune-up Information The LU3000ATD 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 UHF On Channel RF Output at the systems output power level. 7.22 DM8 - Digital Modulator or Axciter Digital Modulator Note: Not present in Translator systems. The Digital Modulators have adjustments for modulation levels, and other related parameters. 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 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 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 Axcera-LU3000ATD FCC Type Acceptance Report Parts List/Tune-up Info June 2007 7-2 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 If Processor Module Assembly (Used with DM8 Only) On the LCD Display, located on the Controller/Power Supply Module, push the button to switch the transmitter 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 pre-distortion 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: • 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 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%. 7.2.4 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 must be in the Enable position, on pins 2 & 3. Set up a spectrum analyzer for 30 kHz resolution bandwidth and 30 kHz video bandwidth. Axcera-LU3000ATD FCC Type Acceptance Report Parts List/Tune-up Info June 2007 7-3 Connect the spectrum analyzer to monitor the intermodulation products of the RF output signal of the Power Amplifier. A typical digital spectrum is shown in Figure 5-1. 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 intermodulation 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 quadratu…
