The Keysight N1922A P-Series Wideband Power Sensor delivers high-accuracy power measurements from 50 MHz to 40 GHz, engineered for radar, electronic warfare, and wireless communications applications. This sensor integrates internal zero and calibration circuitry, eliminating external calibration sources and automating correction routines at power-up. The fixed 1.5 m sensor cable terminates in a precision 2.4 mm male connector and connects directly to compatible Keysight P-Series power meters for real-time signal analysis.
