Agilent/Keysight E9304A-H19

The Agilent/Keysight E9304A-H19 is an average power sensor engineered for precise RF and microwave power measurements spanning 9 kHz to 18 GHz. It extends the capabilities of the base E9304A platform, delivering dual-path measurement architecture with automatic selection between low-power (-50 dBm to 0 dBm) and high-power (0 dBm to +30 dBm) ranges. DC coupling enables accurate low-frequency characterization while supporting a maximum DC voltage of 5 Vdc.

The sensor integrates with Agilent/Keysight EPM, EPM-P, and P-series power meters via Type-N connector, with calibration factors and reflection coefficients stored in onboard EEPROM for automatic meter compensation.
