Used Keysight / Agilent 11722A- Power Sensor Module for HP8901B, 100kHz to 2.6GHz

Product Highlights

The Keysight 11722A sensor module is essentially an RF power sensor with an RF switch at its input. The RF input to the sensor module can be remotely switched between its power sensor and a through path RF cable. The power sensor is used to measure the average power from an external RF source. In use, the sensor module is connected to an RF source. The two output cables of the sensor module are connected to a compatible power measuring instrument such as the 8901B modulation analyzer or the 8902A measuring receiver. The power meter input is a 50 Ω load to the RF source. The power measuring instrument indicates the power dissipated in this load.

• Special care is taken with each sensor module to minimize input SWR and resulting errors. A low SWR attenuator isolates the power sensor from the source under test, reducing mismatch
• The calibration factors of the 11722A are conveniently printed on the sensor module for easy reference
