DVB-T2 QPSK Modulator

Model No: GQ-3800B

Product Overview

      GQ-3800B is a highly reliable single channel DVB-T2 modulator launched by GOSPELL, which is compliant with the EN 302 755(DVB-T2) and EN 302 755 version 1.3.1(T2-Lite, option) standards, and is designed for digital terrestrial distribution by DTT network operators and TV broadcaster.

      GQ-3800B combines dual redundant ASI and Gigabit IP input interfaces, for seamless switching between primary and slave interfaces that can greatly improve the stability and reliability of terrestrial distribution networks. It supports T2 modulator interface (T2-MI) over ASI or IP input, which comes from DVB-T2 gateway, suitable for MFN or SFN- networking.

      The GQ-3800B features a state-of-the-art linear / non linear digital pre-correction that optimizes DTT transmitter performance and efficiency. It offers a wide range of UHF band DVB-T2 RF modulation output (470MHz to 860MHz) and various transmission and modulation modes, such as MFN, SFN, SISO, MISO, SPLP and MPLP. Moreover, it supports Web and SNMP based management and control for local and remote parameters configuration and status monitoring.
