ETL Systems GENUS GNS-381-ODU Outdoor Modular RF Chassis with 100 MHz Reference

ETL Systems GENUS GNS-381-ODU Outdoor Modular RF Chassis with 100 MHz Reference

The ETL Systems GENUS GNS-381-ODU houses up to 19 compatible RF modules in an outdoor enclosure with an integrated 100 MHz reference source and dual redundant power supplies.

Configure the modular outdoor unit with amplifiers, frequency converters, matrices, RF over fibre, redundancy switches and other compatible modules for satellite ground station signal management. Its high-stability ovenised oscillator provides reference distribution, with internal/external source selection and automatic switching. Optional heating and air conditioning extend the operating temperature range, while secure Ethernet control supports remote operation.
