Detailed

 

GQ-3731 ASI+Twin QPSK muxing COFDM modulator can receive 1 channel ASI and 2 channels QPSK signals separately or together and send to COFDM modulator after signal processing. The signals are upconverted to TV channels after IF processing so as to transmit in HFC and MMDS network. The signals can also be bypassed or modulated output by ASI interface. COFDM coding and modulation are under DVB technology criterion and DVB-T standard.
