The HP/Agilent/Keysight 83590A is a broadband RF plug-in module for the Keysight 8350B sweep oscillator mainframe, delivering swept frequency coverage from 2 GHz to 20 GHz. This versatile source performs scalar network analysis, serves as a local oscillator for high-frequency down-conversion, and functions as a standalone RF signal source with excellent harmonic performance.
