The Keysight (formerly Agilent) E4419A is a high-performance, dual-channel, programmable power meter designed for benchtop and automatic test equipment (ATE) environments. Part of the EPM Series, it delivers fast, accurate, and repeatable RF power measurements. With dual-channel capability, it provides two simultaneous power readings on its high-resolution backlit LCD, supporting compatible E-series and 8480-series power sensors.
