Sensor Module for 8901B/ 8902A, 100kHz - 2.6GHz The Agilent (now Keysight) 11722A sensor module was designed for use with the Agilent (now Keysight) 8901B modulation analyzer and 8902A measuring receiver. The 11722A contains a silicon monolithic thermocouple as a power sensing element. With the 11722A sensor module you get all the performance of the 8901B or 8902A, plus superb power measurement accuracy, at a single connector. You can characterize a signal without switching back and forth between the power sensor and the analyzer's RF input. Frequency range: 100 kHz to 2,6 GHz. Power range: +30 dBm (1 watt) to -20 dBm (10 µW). Input SWR (connected to an HP 8901 B or 8902 A): <1,15 for RF power measurements.
