The 11722A Sensor Module was designed for use with the 8901B Modulation Analyzer and the 8902A Measuring Receiver. The unit contains a silicon monolithic thermocouple as a power-sensing element. With the 11722A 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.
