The Agilent/Keysight 8546A is a specialized EMI receiver for electromagnetic interference compliance testing and electromagnetic compatibility measurements. Operating from 9 kHz to 6.5 GHz, it delivers simultaneous peak, quasi-peak, and average amplitude measurements across three tuning bands. CISPR 16-1 compliant, the 8546A supports international standards including CISPR, EN, FCC, VCCI, and VDE, making it essential for modern high-speed equipment qualification.
