The Keysight E9304A is an average power sensor engineered for precise power measurements across an 80 dB dynamic range, from -60 dBm to +20 dBm. Designed for integration with Keysight EPM, EPM-P, and P-series power meters, this sensor delivers accurate results across modulation formats from very low frequency through microwave bands. DC coupling provides excellent low-frequency performance, making it suitable for EMC/EMI testing and general RF characterization. The Type-N male connector ensures direct compatibility with standard test equipment.
