Product Overview

多功能前端接口适配器

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.
