Product Description

QAM Modulator is the key equipment of Digital Cable Television network. It receives MPEG TS via DVB ASI interface, realizes DVB-C channel encoding and QAM modulation, then output intermediate frequency signal, finally upconvert intermediate frequency signal into RF signal. With digital IF modulation, the modulator has the high performance of MER, carrier-to-noise ratio, phase noise, margin of error, etc. It also supports PID filtrating & mapping and PSI/SI updating. MAIN FEATURES The signal coding comply to ITU-T J.*3; PID filtrate and remapping can be configured; PSI/SI information updating possible; Filling MPEG TS automatically and delete empty packet intellectively; PCR emendation supported; **8/**4 data packet adaption automatically; RF output frequency scope *8~**2MHz, in 0.1MHz step; Output level can be adjusted correctly in **8~**8dBuV; Web browser remote control, network upgrade supported.
