Detailed Product Description

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
