The Keysight E9323A (formerly Agilent) is a high-performance peak and average diode power sensor designed for use with EPM-P and P-Series power meters. With a 5 MHz video bandwidth, it is specifically optimized for time-gated peak, average, and peak-to-average ratio power measurements on wideband wireless formats such as W-CDMA and cdma2000.
