Method for network extraction based on phase localization

A method of network extraction based on phase localization using a test setup including a standard includes measuring frequency data using a measuring instrument connected with the test setup by performing a frequency sweep across an identified bandwidth, correlating filter functions as required against the measured frequency domain data to localize phase across the test setup, removing excess phase rotation and solving for inner plane match of the test setup based on known composite measurement and previously identified components of the test setup.
