Product Overview

GQ-3760 is a professional DTBM modulator which can receive DTV transport streams from ASI interfaces, and then modulate the signals by DTMB standard (GB20600-2006). It finally outputs the signals after up-conversion(30MHz~860MHz) via RF outputs. This device has outstanding RF performance which can be used in terrestrial DTV network head-end. It also supports the WEB/SNMP-based management.

Main Features:

Support modulation modes of single carrier and multicarrier
Able to work in 4QAM-NR/4QAM/16QAM/32QAM/64QAM mode
Four input interfaces
Input TS bit rate range: 1.5 Mbps~100.0Mbps
Output TS bit rate range: 5.2 Mbps~32.4Mbps
MER＞40dB
Output signal bandwidth:7.56MHz (roll-off factor=0.05)
RF frequency range: 30MHz~860MHz
Output EPL range: 95dBuV~115dBuV(0.5dBuV step size)
Input TS support 188/204 data packet length (self-adaptive)
Extra-large buffer design, support boost & uniform TS input, with re-unifying of boost input TS
Real time statistics of system input bit rate and effective bit rate
Support the filtering of input empty data packets and the padding of output data packets
PCR auto-correction
Tracking filter circuit design to ensure outstanding out-of-band rejection
Support Web-based management and online remote update
Power failure memory recovery
