The Keysight (Agilent) E9300B is an average power sensor designed for measuring RF and microwave signals from 10 MHz to 18 GHz across a wide dynamic range of -30 to +44 dBm. Utilizing a patented diode-attenuator-diode topology, the sensor ensures square-law region operation for accurate and modulation-independent average power measurements. It features exceptionally low SWR to minimize mismatch uncertainty and stores calibration, linearity, and temperature compensation data on an internal EEPROM for plug-and-play compatibility with EPM, EPM-P, and P-series power meters.
