HDQ-5031 1-2CH DVB-T Modolator

HQ-5031 is a professional COFDM digital modulator which can receive the DTV transport streams from ASI, IP interfaces, and then modulate the signals by DVB-T standard. It finally outputs the signals after up-conversion via RF outputs. This device has outstanding RF performance which can be used in terrestrial DTV network head-end systems
