The Marconi IFR Aeroflex 56911/900 is a precision power sensor engineered for accurate RF and microwave power measurements across 10 MHz to 20 GHz. It delivers stable, repeatable readings essential for characterization, maintenance, and compliance testing of communication systems, radar, and RF equipment. The sensor uses thermocouple or semiconductor thermocouple sensing elements and connects via precision N-type male connectors to compatible Marconi IFR Aeroflex power meters.
