Agilent/Keysight E9301A

The Agilent/Keysight E9301A is an average power sensor engineered for precision measurements across RF and microwave applications. Operating from 10 MHz to 6 GHz, it delivers absolute accuracy of ±0.02 dB (logarithmic) or ±0.5% (linear) over an 80 dB dynamic range spanning -60 dBm to +20 dBm. The diode-based sensor measures average power across all modulation formats - including W-CDMA, CDMA (IS-95), TDMA, OFDM, multi-tone, and continuous-wave signals - making it ideal for wireless communications, satellite equipment, and cable TV infrastructure testing.
