The Keysight (Agilent/HP) E7405A is a rugged, portable EMC standard analyzer operating from 9 kHz to 26.5 GHz. Based on the robust ESA-E series spectrum analyzer platform, it provides the essential capabilities needed for in-house EMI precompliance testing and diagnostic evaluation. The E7405A features built-in CISPR bandwidths and detectors, a standard built-in preamplifier, and log sweep functions to streamline emissions testing. It is designed to work seamlessly with broadband antennas, LISNs, absorbing clamps, and close field probes (such as the 11940A and 11941A), and can operate independently or as part of the Keysight 84115EM precompliance system.
