The Agilent/Keysight 8593EM is a high-performance EMC analyzer operating from 9 kHz to 22 GHz, purpose-built for electromagnetic compatibility precompliance testing and radiated/conducted EMI measurements. The instrument combines spectrum analysis with automated EMC measurement functions, enabling engineers to identify, measure, and document emissions across products with clock frequencies up to 4.4 GHz. Dual-mode operation allows instant switching between EMI analysis and full-spectrum analysis modes via single key press, extending utility beyond EMC-only workflows.
