The Keysight E9301B is a diode-based average power sensor engineered for precise power measurement across RF and microwave frequencies. It integrates with Keysight power meters to deliver accurate readings across all modulation formats, making it ideal for wireless communications, radar, and device testing applications. The sensor spans 10 MHz to 6 GHz with a 74 dB dynamic range and maximum input of +44 dBm (25 W). Dual independent measurement paths—one optimized for high power (+20 dBm to +44 dBm) and one for low power (−30 dBm to +20 dBm)—ensure measurement fidelity across its full range. Internal EEPROM stores calibration factors, linearity data, and temperature compensation coefficients to maintain accuracy throughout the sensor’s operating envelope. Low SWR design minimizes mismatch uncertainty.
