QPSK Modulator(XG913s01)

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.

According to the formula input bit rate(generally adopts 188
format),output symbol rate,output bandwidth
Output bandwidth (Hz) = symbol rate (Sps)x Roll-off coefficient
(generally roll-off coefficient=1.25 )
