The Keysight (Agilent) E9301A is an E-series average power sensor designed for measuring RF and microwave power across a wide dynamic range, regardless of signal modulation. Operating from 10 MHz to 6 GHz, it utilizes a patented diode-attenuator-diode topology to ensure high measurement accuracy, low standing-wave-ratio (SWR), and low harmonic generation. Calibration factors, linearity, and temperature compensation data are stored internally in its EEPROM, simplifying setup when used with compatible Keysight/Agilent EPM, EPM-P, and P-series power meters.
