he Keysight 11722A contains a thermal coupled power sensor and a bypass switch that directs the RF signal to the power sensor or directly to the Keysight 8902A. When measuring RF power the RF signal is routed directly to the power sensor in the sensor module. The sensor module can measure RF Power from 100 kHz to 2.6 GHz. When making all other measurements the RF signal is routed through the RF cable directly to the 8902A. The frequency range of the 8902A is 150 kHz to 1300 MHz.
While the 11722A will enable the 8902A to make broad-band RF power measurements from 100 kHz to 2.6 GHz, it does not extend any of the other measurements. The 8902A, 11793A, and the 11722A can make Tuned RF Level measurements from 2.5 MHz to 2.6 GHz.
