Automation and Real-time Verification of Passive Component S-parameter Measurements Using Loss Factor Calculations

An automated S-parameter testing approach, built around a LabVIEW program, is described that adds important capabilities to a microwave test setup. A real-time check on S-parameter data using total loss calculations is shown to be a good indicator of m...

In developing microwave models, real-time verification of characterization data should be considered a priority to ensure its integrity. Sound models must be built upon accurate measurement data, and, as is generally the case, the ‘garbage in – garbage out’ principle applies to model extraction. Even if an instrument calibration...
