The Agilent/Keysight E7404A EMC Analyzer is a spectrum analyzer engineered for electromagnetic compatibility testing across 30 Hz to 13.2 GHz. It delivers peak, quasi-peak, and average detections for pre-compliance EMI measurements in development and manufacturing environments. The instrument supports radiated emissions testing with broadband antennas, conducted emissions via LISN, and near-field diagnostics using close field probes.
