The Keysight (formerly Agilent / Hewlett-Packard) E4419B is a high-performance true dual-channel RF and microwave power meter belonging to the EPM Series. Designed for both benchtop and automatic test equipment (ATE) applications, it provides fast, accurate, and simultaneous dual-channel power measurements when paired with compatible 8480 or E-series power sensors. The meter achieves high measurement speeds of up to 100 readings per second over GPIB and features built-in backward code compatibility with the legacy HP 438A.
