Product ManualManual

The 7800R4x4-RF/7800R4x4-RFI is a modular RF signal switch for routing and monitoring L-Band, IF and DTV, as well as other signals within a satellite communications facility. Starting from a base 4x4 configuration, the switch can be expanded to support distributive (fan-out) or combining (fan-in) systems with additional inputs and outputs using software license keys.

Advanced features such as slope compensation, automatic gain control, salvo operations, monitoring and alarm reporting of critical signal parameters such as input signal presence and signal-level provide flexible RF signal management are offered. Optional per port selection of 13/18V DC LNB power with active overload and short circuit protection. Direct optical input is also supported using 2307LR miniature fiber receiver.

The 7800R4x4-RF/7800R4x4-RFI is offered with variety of control interfaces and available to provide quick and simple PC or panel-based control for crosspoint control and system configuration. Additionally, this flexible routing switch can be controlled, configured and monitored via Web GUI and/or SNMP control over Ethernet, using Evertz® VistaLINK® or other monitoring and control software. This platform can be housed in Evertz 7800FR 3RU or 7801FR 1RU* multiframe.
