General
The XG913S01 QPSK Modulator is a head-end QPSK DVB Modulator with RF output. It adopts digital RF modulating technology and achieves high performance in Modulation Error Rate (MER), Carrier-to-Noise Ratio, and Phase and Level Distortion specifications. The XG913S01 QPSK Modulator inputs transport stream and outputs 500MHz-1000MHz or 950-2150MHz or 2500-2700MHz RF signal. The XG913S01 is good for digital satellite television stations and long-distance microwave backbone network transferring.
