The Agilent/Keysight 85422E Receiver RF Section is the RF front-end component of the 8542E EMI test receiver system, delivering precise signal reception and analysis across 9 kHz to 2.9 GHz. This modular unit captures and processes RF signals for EMI and conformance testing, with compliance to CISPR 16-1 and industry standards including CISPR, EN, FCC, VCCI, and VDE. It operates standalone for pre-compliance testing and integrates with the 85420E RF Filter Section to form a complete EMI compliance receiver.
