The Keysight (Agilent) 11722A is a sensor module that extends RF power measurement capabilities across the 100 kHz to 2.6 GHz frequency band. It integrates a silicon monolithic thermocouple power sensor with an internal bypass switch, enabling RF signals to be routed to the sensor for measurement or directly through to a connected instrument without manual switching. The module delivers power measurements from -20 dBm to +30 dBm (10 µW to 1 W) with ±2% to -4% linearity across its operating range.
