Introduction

Down Converters are used to translate the frequency of a source to a

lower frequency that is compatible with tuneable low noise reference

sources. The HP 3048A supports any manually controlled down converter,

including the HP 11729C which is also supported under system control.

This section describes how the down converter is configured in the

HP 3048A System, specifically the HP 11729C, and the considerations to

be considered when using a down converter to make noise measurements.
