The Marconi IFR Aeroflex 56930/900 is a thermocouple-based RF power sensor engineered for accurate power measurement across the 10 MHz to 18 GHz frequency band. It delivers ±0.2 dB accuracy after calibration with a 0 dBm, 50 MHz power reference, making it suitable for precision RF and microwave system testing, calibration, and production verification. The sensor integrates directly with Marconi, IFR, and Aeroflex power meter platforms, providing field-proven reliability in laboratory and field environments.
