QPSK to QAM modulator is a high performance equipment combining QPSK decoding with QAM modulation. It receives DVB transport stream from satellite receiver, encoder, multiplexer, DVB gateway, scrambler, video server etc and provide IF or RF output after RS encoding, convolution interweaving process and QAM modulation. This transformer is mainly used in digital cable TV head end system to transfer satellite decoder, digital multiplexer and providing an economical solution. It also can be used as a pure QAM modulator when receiving the DVB-ASI input stream.
