Product ManualManual

The 7882DM-SAT is a complete hardware-based solution for demodulating digital DVB-S/S2/S2X satellite signals. Base model offers quad RF inputs with one demodulator, software upgradeable to utilize built-in quad demodulators. Built with a modular form-factor, along with multiple inputs and multiple demodulators per card, the 7882DM-SAT represents one of the highest density and most flexible solutions in the industry. This demodulator is fully hardware-equipped with default features such as four RF input ports, four ASI ports (configurable as inputs or outputs), one IP (RJ-45) port and two conditional access slots.

Applications include signal reception for broadcasters, cable, DTH and IPTV providers, or any other small to large head-end operators who need to receive and redistribute satellite content. The 7882DM-SAT provides ASI and IP outputs, ideal for turnaround, transcoding, 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 IRD solution.

Monitoring parameters such as Es/N0, demodulator lock, RF power and FEC activity provide extensive information on received signal quality and robustness. 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.

For applications requiring decryption, two CA slots are available for installation of customer supplied DVB-CI compliant conditional access modules.
