The Keysight (formerly Agilent) E9300H is an E-series diode-attenuator-diode average power sensor designed for high-accuracy RF and microwave power measurements. Operating across a broad frequency range from 10 MHz to 18 GHz, it delivers accurate average power measurements of all modulation formats over a wide 80 dB dynamic range (-50 to +30 dBm). Its extremely low SWR minimizes mismatch errors, and built-in EEPROM calibration factors ensure excellent repeatability without manual entries.
