Agilent / Keysight 85462A Receiver RF Section, 9 kHz to 6.5 GHz

The Agilent/Keysight 85462A Receiver RF Section is a component module that extends spectrum analyzer capabilities for electromagnetic interference testing across 9 kHz to 6.5 GHz. Operating in three distinct bands - 9 kHz to 50 MHz, 20 MHz to 2.9 GHz, and 1 GHz to 6.5 GHz - this unit forms the core of the 8546A EMI test receiver system when paired with the 85460A RF Filter Section. The module delivers simultaneous measurement of peak, quasi-peak, and average amplitude with automatic overload detection and auto-ranging functionality.

It incorporates a preamplifier, tracking generator (9 kHz to 2900 kHz), three CISPR filters, and IF overload detection to support rapid EMI compliance verification.
