The Keysight N1922A is a P-Series wideband power sensor that delivers precise power measurements across RF and microwave frequencies from 50 MHz to 40 GHz. Built for high-performance aerospace and defense, calibration laboratory, and wireless communications applications, it measures average power, peak power, pulse characteristics, and statistical parameters of complex wideband signals. The sensor integrates an internal DC reference source with switching circuits for in-situ zeroing and calibration, eliminating connector wear while reducing measurement uncertainty. Calibration factors, linearity, temperature, and bandwidth correction data are stored in on-board EEPROM.
