System Overview The LL200ATC (1304937) is made up of the trays listed in Table 8-1. Table 8-1. LL200ATC Major Trays and Assemblies MAJOR ASSEMBLY DESIGNATOR TRAY/ASSEMBLY NAME DRAWING NUMBER A1 DVB-T /H Modulator Model PT-5780 A2 Driver Assembly 1305021 A3 External Amplifier Assembly 1305863 8.4.1 DVB-T Modulator Tray/Driver Tray/External Amplifier Tray The LL200ATC is a complete DVB-H transmitter capable of operating at an output power of 200 watts (average). Functionally, the LL200ATC is comprised of a modulator (Pro- Television, Model 5780) and driver/amplifier 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 QAM or QPSK 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/H Modulator Tray is connected to the Driver Tray (driver), which drives the input to the External Amplifier Tray. 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. Axcera-LL200ATC FCC Type Acceptance Report Operational Description March 2005 8-4 An IF Signal centered at 36 MHz at a level of 0 dBm average is applied to the Upconverter Control board.
