DVB-T Professional Receiver

 Description

DMB-6118 DVB-T Professional Receiver adopts DIBCOMs high performance demodulation chip which can receive DTV programs stably at the harsh environment where the signal are weak.With 2 independent tuner and demodulator, DMB-6118 DVB-T Professional Receiver can be set into cascade modes to improve the sensitivities and can be used as 2 independent professional receivers. It supports hierarchical modulation, which can demodulate and output LP and HP signal at the same time.

Main features:
Compliant with ETS 300744 standard and all DVB-T modes supported
6, 7 and 8 MHz RF channel in VHF Band III or UHF band IV & V
70 MHz RF input version available for ENG application
4 modes of operation: dual channel, antenna diversity, hierarchical, redundant
MER, BER, RF level, C/N Monitoring capabilities ±350 KHz automatic frequency correction
Web browser remote control, SNMP is optional
