DVB-T2 Modulator

GQ-3800

GQ-3800 is a single-channel DVB-T2 modulator. It has two ASI inputs, and provides one IP signal input interface for DVB-T2 SFN/MFN. It can receive signal in both standard TS format and T2-MI format, and outputs one DVB-T2 (30MHz～900MHz) modulated signal after channel coding, interleaving and modulation. It operating parameters can be configured locally or remotely via DVB-T2 gateway. GQ-3800’s output signal can be directly connected with power amplifier to constitute a digital terrestrial transmitting station.
