The Agilent/Keysight E7405A is a portable EMC spectrum analyzer for in-house EMI precompliance testing, radiated and conducted emissions analysis, and signal diagnostics across 9 kHz to 26.5 GHz. Built-in preamplifier (20 dB gain, 1 MHz to 3 GHz), automated EMI measurements with peak/quasi-peak/average detection, and multi-band architecture enable efficient signal characterization for compliance validation.
Technical Specifications
Frequency Coverage: 9 kHz to 26.5 GHz (Band 0–4). Optional lower-frequency extension (Option UKB) extends Band 0 to 30 Hz DC coupled or 100 MHz AC coupled, with upper limit 3.6 GHz.
