The Marconi IFR Aeroflex 6924 is a precision RF power sensor engineered for accurate power measurements across microwave and millimeter-wave frequencies. Operating from 30 kHz to 40 GHz, it delivers measurements from -70 dBm to +44 dBm with calibration traceability to national standards. The sensor integrates with Marconi and Aeroflex power meters and test sets for laboratory, bench, and field applications requiring low measurement uncertainty and high overload protection.
