ASI+QPSK/8PSK Multiplexing QAM Modulator GQ-3695

<span lang="EN-US" style="font-size: 10.5pt; line-height: 150%; font-family: "Times New Roman"">GQ-3695 ASI+QPSK/8PSK Multiplexing QAM Modulator is a multifunctional digital headend equipment, which receives one way ASI and one(or two) way DVB-S/S2 Satellite Signals, multiplexing the signals and then outputing the multiplexed RF signals. This Modulator is mainly used in digital headend machine room to convert the satellite signal and local program stream into digital singal that can be received by STBs in DTV Cable Network.
