Agilent / Keysight E9300B E-Series Average Power Sensor 10MHz to 18 GHz

The Keysight E9300B is an E-Series average power sensor delivering accurate measurements across 10 MHz to 18 GHz with a dynamic range of 74 dB. It measures average power for all modulation formats - including W-CDMA, CDMA, TDMA, OFDM, multi-tone, and CW signals - making it bandwidth independent and suitable for high crest factor applications. The sensor employs dual independent measurement paths: a low power path covering −30 dBm to +20 dBm and a high power path extending to +44 dBm.

This architecture automatically selects the optimal range for each measurement, eliminating manual switching. A Type-N male connector interfaces with compatible Keysight power meters.
