The Agilent/Keysight E4418B EPM Series Single-Channel Power Meter is a single-channel RF and microwave power measurement instrument engineered for benchtop use and integration into automatic test equipment (ATE) systems. It delivers high accuracy, speed, and repeatability across a wide dynamic range, accommodating diverse sensor types and measurement scenarios. The meter supports a broad compatibility ecosystem with Agilent/Keysight 8480, N8480, and E-Series power sensors, enabling flexible measurement configurations from 9 kHz to 110 GHz with power levels spanning -70 dBm to +44 dBm.
