PCR Auto Correction DTMB DVB-T2 Modulator GQ-3760 Four Input Interfaces

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)
