DVB-S/S2 8PSK/APSK/QPSK Modulator
Model No:GQ-3780
GQ-3780 is a professional DTV Satellite Modulator which can receive the DTV transport streams from ASI interface, RS-530/422 interface (optional), G703 interface (optional), LVDS interface (optional), and then modulate the signals by DVB-S/S2 standard. It finally outputs the signals after up conversion at mid-frequency or L-band via RF or IF outputs. This device has outstanding RF performance which can be used in satellite DTV network head-end systems.
