The HP/Agilent 84811A is a peak power sensor engineered for precise measurement of RF and microwave signals from 100 MHz to 18 GHz. Built for pulsed and modulated signal characterization in radar, communications, and electronic warfare applications, this sensor delivers the fast response time and sensitivity required for dynamic peak power analysis. The unit connects via Type-N male connector and operates across 0 °C to +55 °C. It detaches from compatible peak power meters for independent operation, calibration, or replacement, and ships with a 4-foot flexible cable.
