A New Coaxial 40 GHz Vector Network Analyzer

A new network analyzer with enhanced user features has been described. The source locking concept provides the high speed synthesized signal that leads to fast operation. A new sampler design utilizing the K Connector permits operation to 40 GHz which covers the important Ka band. A color display is incorporated with system flexibility to display a single trace or a display of as many as eight traces showing four S parameters simultaneously. Color has been used to provide easy to interpret output data as well as a user interface that makes it easy to use the full functional capability of the analyzer.
