System Overview The LL5ATC (1306313) is made up of the trays listed in Table 8-1. Table 8-1. LL5ATC Major Trays and Assemblies MAJOR ASSEMBLY DESIGNATOR TRAY/ASSEMBLY NAME DRAWING NUMBER A1 DVB-T Modulator Model PT-5780 A2 Driver Assembly 1305021 8.4.1 DVB-T Modulator Tray/Driver Tray The LL5ATC is a complete DVB-H transmitter capable of operating at an output power of 5 watts (average). Functionally, the LL5ATC is comprised of a modulator (Pro-Television, Model 5780) and driver tray. The 36 MHz IF signal from the modulator is applied to the input of the driver/amplifier which provides spectral shaping of the IF signal in accordance with Occupied Bandwidth requirements of the Rules and Regulations. The modulator receives a serial bit stream, consisting of multiplexed MPEG-2 transport streams, translates the signal to a Quadrature Amplitude Modulated (QAM) format, converts the digital information to analog, and modulates the signal to IF (36 MHz). The modulator tray’s IF output is routed to the driver/amplifier tray for IF signal processing, upconversion to the 1670-1675 MHz band, and final amplification. The driver/amplifier tray utilizes ALC circuitry for automatic level control of the output signal to maintain a constant power level. Both modulator and driver/amplifier trays are 19-inch rack mount assemblies and can be supplied with or without a cabinet. Both trays are supplied complete with cables and cabinet slides. The output of the DVB-T Modulator Tray is connected to the Driver Tray (driver). 8.4.1.1 Metering Module (Driver) This assembly has circuitry that is used to measure the average power of up to four RF inputs. Each RF input is split on the Metering Board (1304922), with some of the signal being applied to an average power detector, and the rest of the signal sent to the front panel sample to allow the operator to monitor the RF signal with his own test equipment. The output of each detector is sent to the transmitter's system control via the Backplane that the assembly plugs into. 8.4.1.2 L.O. / Upconverter Module (Driver) This assembly converts either one or two separate 36 MHz IF signals to either one or two RF outputs at a frequency of 1670-1675 MHz. It contains an Upconverter Control board (1304780), an LO Generator board (1304940) and either one or two Upconverter boards (1304929). The description below is for one half of the upconverter. The IF and upconverter paths can be duplicated to provide two outputs when needed. The second IF path is always present, but not used in single output upconverters. A second Upconverter board is added for dual output transmitters. An IF Signal centered at 36 MHz at a level of 0 dBm average is applied to the Upconverter Control board. A sample is applied to a peak detector, which checks for the Axcera-LL5ATC FCC Type Acceptance Report Operational Description July 2005 8-4 presence of an IF input. If the input is not present, an alarm is generated and displayed on the module's front panel, and is also n…

Axcera-LL5ATC FCC Type Acceptance Report Parts List/Tune-up Info July 2005 7-1 7. PARTS LIST/TUNE-UP INFO 7.1 Parts List The transmitter, can be subdivided as follows: DVB-T Modulator Tray (See modulator manual for tune-up info) Driver Tray: ƒ Metering Module ƒ L.O. / Upconverter Module ƒ Control & Monitoring / Power Supply Module • Power Amplifier Module 7.2 Tune-up Information The LL5ATC transmitter was aligned at the factory and should not require additional alignments to achieve normal operation. 7.2.1 Setting up Manual Gain Turn the Manual Gain Pot on the front panel of the Upconverter full CCW. Switch the Auto/Manual Gain Switch to the left (Manual) Gradually turn the manual gain pot clockwise while monitoring the output power on a power meter connected to the output of the transmitter is 100%. 7.2.2 Power Calibration Connect a Power meter to the output sample of the transmitter. Note the Insertion loss from the output to the sample port. Enter that offset into the Power meter's Offset Rel function, and set the reference frequency to 1670 MHz. Navigate to the Transmitter Setup Menu on the System Controller and enter that menu. Scroll down until the A Output Power Adjust screen is reached. Use the Up/down Arrows to adjust power to desired output power. Scroll down to the A Output Power Cal screen. Adjust Power Calibration until meter reads 100%. 7.2.3 Setting up AGC Step 1: Navigate to the Transmitter Setup Menu on the System Controller and enter that menu. Scroll down until the A Output Power Adjust screen is reached. Use the Up/down Arrows to adjust power to 100%. (Power Calibration must have been done first) Step 2: Scroll down further to Inner Loop A Gain menu is reached. Increase the Inner Loop Gain while watching the output power. Keep increasing until the output power begins to drop. Note the setting on Inner Loop gain, and reduce the setting by 10%. Example: The Inner Loop Gain setting where power begins to move is 210. Reduce the setting by 21 to 189. Axcera-LL5ATC FCC Type Acceptance Report Parts List/Tune-up Info July 2005 7-2 NOTE: If adjusting the Inner Loop gain causes the power to rise immediately, then the AGC has been running on Inner Loop Gain, not Outer Loop Gain. Go back to step 1, reduce the power to 50%, then go to step 2 and reduce the Inner Loop A Gain until the power stops rising or you have reached 110%, whichever comes first. If you reach 110%, go. Repeat as many times as you need to until the Inner Loop does not affect power. Once the power stops rising when Inner Loop Gain Continue to lower the Inner Loop gain further by 20%, then go back to step 1 a final time. Bring the power back up to 100% and go to step 2 one final time. 7.2.4 Overdrive Go to the Transmitter Setup Menu, and scroll down to the A Output Power Adjust screen. Turn the Output power up to 10%. Then scroll down to the A Overdrive screen and lower the Overdrive setting until power just starts to drop. Go back to the A Output Power Adjust screen and reduce the power to 100%. 7.2.5 Reflected Power Calibration Connect a Power meter to the Reflected sample of the transmitter. Note the Insertion loss from the output to the sample port. Enter that offset into the Power meter's Offset Rel function, and set the reference frequency to 1670 MHz. Navigate to the Transmitter Setup Menu on the System Controller and enter that menu. Scroll down until the A Output Power Adjust screen is reached. Use the Up/down Arrows to adjust power to 20% of the desired output power. Swap the forward and reflected power cables on the transmitter's output coupler. Scroll down to the A Output Power Cal screen. Adjust Power Calibration until meter reads 20%. Return cables to their correct position. Go back to the A Output Power Adjust screen and return Output power to 100%. 7.2.6 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. 7.2.7 Linear and Non-linear Pre-correction set-up Refer to the Pro-television manual for this procedure. The Transmitter is ready for normal operation. This completes the detailed alignment procedures for the LL Series transmitter.
