Holzworth HX5100 Series Electronic Phase Shifters are available for fully automating the residual / additive phase noise measurement process while using an HA7000C Series Phase Noise Analyzers.

The phase shift operation is managed via a DC tune voltage that is controlled by a Holzworth phase noise analyzer to bring full automation to the additive phase noise measurement process. This is an optimal scenario for ATE test scenarios as well as laboratory test operations.

  For more information on automated additive phase noise test setups using the HA7000 Series Phase Noise Analyzers, refer to the Holzworth's article for the April 2013 issue of MW Journal.
