The Agilent/Keysight 11722A is a sensor module for RF power measurement spanning 100 kHz to 2.6 GHz. It integrates a silicon monolithic thermocouple sensing element with an internal bypass switch to route signals to either the power sensor or a through-path connection, enabling simultaneous power characterization and receiver analysis without instrument switching.
