Work Microwave VSCD-L Compact Satellite Downconverter

WORK Microwave’s integrated, compact frequency converter is a new cost-effective option for satellite operators, integrators, and teleports made possible by the latest advancements in RF chipsets.

Enhancements

Compact Design: Designed specifically for operators using classic IF frequency bands, the compact version enables operators to support multiple simultaneous channels in one unit, saving significant rack space and costs.

Input and Output Adjustable Attenuator: With two software adjustable attenuators the operator can now optimize the system performance regarding noise figure and intermodulation.

RF-RMS Detector: Through a new RMS Detector the user can perform a real time monitoring of RF-power, giving the opportunity to initialize a switch over to spare units in case of RF power loss or simply to monitor the system.

Scalability

Together with WORK Microwave’s new compact N:1 Redundancy Switch (RSCC-N) very compact and flexibly redundancy solutions up to 8:1 can be designed, giving the user the possibility to start with a small group of converters and expand it later to 8 operational units and one spare unit.

Operating and control – easy integration into your system

The converters can be operated via the push buttons on the front panel using intuitive display menus or via remote control (RS232, RS422/485 and TCP/IP over Ethernet). Detailed monitoring of the system status and a summary alarm output (dual change over switch contacts) are provided. For the remote control either ASCII string-based commands as well as addressable, packet based commands are provided. Remote monitoring and control through SNMP and a Web browser interface is also available.
