HT105-1 QPSK Modulator complies DVB-S standard. The signal is compressed by MPEG-II and processed with other data then finally send to QPSK Modulator.
Detailed introduction to QPSK rf modulator:
Outline
HT105-1 QPSK Modulator complies DVB-S standard. The signal is compressed by MPEG-II and processed with other data then finally send to QPSK Modulator. After Modulating it output L-Band frequency directly which can be widely used for microwave point to point transport, Satellite DTV, Digital Broadcasting, VOD, Internet, Video Conference and etc
