The Agilent/Keysight E4419A EPM Series is a dual-channel, programmable average power meter engineered for precision measurements across 100 kHz to 110 GHz. Built for both benchtop operation and integration into automatic test equipment systems, the E4419A delivers measurement speeds up to 100 readings per second with E-series sensors or 200 readings per second in FAST mode. Its true dual-channel architecture enables simultaneous power readings on two independent channels with high-resolution backlighting. The meter accepts Agilent/Keysight 8480 series and E-series power sensors—excluding E9320A—and achieves twice the measurement speed of the 437B when paired with 8480 series sensors. Remote control is provided via GPIB and RS-232/RS-422 serial interfaces with SCPI command compatibility. The E4419A maintains code compatibility with the 438A and complies with CE and CSA standards.
