N1922A

Keysight Technologies (Agilent HP)Power Sensors

The Keysight N1922A is a P-Series wideband power sensor designed for high-performance peak, average, and peak-to-average ratio measurements over a broad frequency range of 50 MHz to 40 GHz. Operating in conjunction with the N1911A and N1912A P-Series power meters, the N1922A provides internal zeroing and calibration to streamline test setups in aerospace, defense, and wireless communications applications.
