Agilent / Keysight E7402A EMC Spectrum Analyzer, 9 kHz to 3 GHz

The Agilent/Keysight E7402A is a portable EMC spectrum analyzer operating from 9 kHz to 3 GHz, purpose-built for pre-compliance testing and radiated/conducted emissions evaluation. This instrument delivers DANL performance to –150 dBm, resolution bandwidth from 1 Hz to 5 MHz with dedicated EMI bandwidths (200 Hz, 9 kHz, 120 kHz, 1 MHz), and a built-in 20 dB preamplifier for enhanced sensitivity in low-level measurements. The analyzer includes factory-programmed limit lines covering CISPR, FCC, and EN EMC standards, eliminating manual threshold entry for routine compliance workflows.
