7880DM Series

Professional ATSC/DVB-T/T2/DVB-C/C2/ISDB-Tb/DVB-S/S2 Demodulators

Interact with this product in a Layout Tool:

The 7880DM series is a complete hardware based solution for demodulating digital terrestrial ATSC/8VSB/ ISDB-Tb , QAM/ DVBC/ DVB-C2 cable signals DTV signals or digital DVB-S/S2 satellite signals. With a modular form-factor, the 7880DM represents one of the highest density and most flexible solutions in the industry.

Applications include signal reception for satellite, cable, DTH and IPTV providers, or any other small to large head-end operators who need to receive and distribute local content. The 7880DM can provide ASI and IP output, ideal for turnaround, transcoding, transporting, monitoring or other applications where the received signal remains in the compressed domain. For baseband output, the demodulator may be coupled with an Evertz decoder module, providing a full receiver solution.( for more info, check CRP-9000 platform for SDI decoding)

Monitoring parameters such as EsNo, RF Power, MER, BER and packet errors present a convenient solution for broadcasters and cable companies who wish to not only receive, but also remotely monitor signal quality. These parameters as well as full control of the demodulator are relayed over SNMP, for convenient remote access using Evertz' own VistaLINK® PRO SNMP monitoring and control package
