Agilent / Keysight E9300A E-Series Average Power Sensor 10MHz to 18 GHz

The Agilent/Keysight E9300A E-Series Average Power Sensor delivers precise average power measurements from 10 MHz to 18 GHz with an 80 dB dynamic range. Built on patented diode-attenuator-diode (MBID) topology, this sensor maintains measurement diodes in the square-law region to ensure accuracy across all modulation formats - including W-CDMA, CDMA, TDMA, OFDM, multi-tone, and CW signals. The sensor operates independently of signal bandwidth and integrates with Keysight EPM, EPM-P, and P-series power meters through automatic EEPROM-stored calibration factor retrieval.
