Keysight (formerly Agilent T&M) 89411A Network Analyzer Down Converter

The Keysight 89411A IF downconverter works with the Keysight 89410A to provide narrowband vector signal analysis at RF and microwave frequencies. The 89411A converts a 21.4 MHz IF output from an external receiver to the input frequency range of the 89410A. This downconverter is also compatible with the Keysight 89440A and 89441A. The 89411A is designed for use with various Keysight microwave spectrum analyzers and other devices with compatible 21.4 MHz IF outputs. Frequency coverage is thus available over the complete frequency range of the microwave receiver or analyzer.
