The Agilent/Keysight E7403A is a portable EMC analyzer engineered for electromagnetic compatibility testing across 30 Hz to 6.7 GHz. It delivers pre-compliance EMI testing, radiated and conducted emissions measurement, and full spectrum analysis with peak, quasi-peak, and average detection modes. The instrument stores up to 2000 signals with amplitude data, displays dual limit lines with margins, and applies corrections for antennas, cables, and amplifiers. A built-in 20 dB preamplifier extends low-level measurement capability, while optional tracking generator support (up to 3 GHz) enables stimulus-response analysis.
