Agilent/Keysight 11792A

The Agilent/Keysight 11792A is an RF power sensor module engineered for precision power measurements spanning 50 MHz to 26.5 GHz. It integrates with the Agilent 8902A measuring receiver and, when paired with the 11793A microwave converter, extends measurement capability to the full upper frequency limit. The module delivers accurate characterization of AM, FM, and phase modulation across its operating range with exceptional linearity and return loss performance.
