The Keysight (Agilent/HP) E4417A is a high-performance, dual-channel EPM-P series power meter designed for precise peak, average, peak-to-average ratio, and time-gated power measurements. Delivering a 20 MSa/s continuous sampling rate, it provides reliable single-shot and continuous measurements on wide-bandwidth complex signals when paired with E9320 series peak and average power sensors. It features extensive backward compatibility with existing standard and CW sensors, and is equipped with multiple pre-defined configurations for common wireless communication formats.
