DVB-T2 QPSK Modulator

Model No: GQ-3800B

Single Channel DTV Modulator DVB-T2 QPSK Modulator Dual Redundant ASI Gigabit IP

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.

Main Features

· Complies with DVB-T2 and T2- Lite (software option) standards

· Supports data input in T2-MI or MPEG-TS format

· Supports SFN/MFN

· Supports Single / Multiple Input Single Output (SISO/MISO)

· Enhanced Digital Adaptive Pre-correction

· Supports linear / non linear Digital Adaptive Pre-correction, optional enhanced DAP

· Dual ASI and IP input, supporting independent or 1+1 hot redundant(seamless switch)

· QPSK/16QAM/64QAM/256QAM(standard or rotated) mode

· Multiple signal bandwidth can be supported: 5M,6M,7M,8MHz

· Modulation RF output level up to 0dBm

· Supports PAPR adjustment for output signal

· Modulation module is designed based on FPGA to ensure the stability of device

· Adopt extra large cache memory for both uniform and burst input stream

· Self adaptive filter circuit design ensures outstanding out-of-band rejection

· Supports Web/SNMP-based network management and monitoring, online upgrade of firmware
