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.

– Typical Applications

Average power measurement of digital modulated signals, multi-carrier waveforms, and continuous-wave RF sources across microwave and sub-millimeter frequencies.

– Compatibility & Integration

Direct integration with Keysight EPM, EPM-P, and P-series power meters. Not compatible with legacy HP 430-Series, HP E1416A, or HP 70100A instruments. Requires compatible firmware and DSP code versions.
