P378 - Recommended Practice for Scattering Parameter Measurements and Uncertainty Analysis Using Network Analyzers

Provide definitions of terms commonly used by users and manufacturers of vector network analyzers. Define and describe measurement techniques, measurement errors, and the use of standards to quantify the effects of these errors. Assist users to specify, and manufacturers to meaningfully describe essential performance parameters. Assist users to verify the specified performance parameters with proven test methods and well defined standards. Provide users with examples to evaluate and express the uncertainty of measurements made using VNAs.Vector Network Analyzers (VNAs) are used to measure reflection and transmission coefficients of multi-port networks at radio, microwave and millimeter-wave frequencies from a few kHz to 110 GHz and beyond. This standard provides a common base for analysis of measurements made on vector network analyzers. A description of terminology is included so that a common language can be used to understand the measurement instruments and parameters, the methods of measurement, and the uncertainty associated with a measurement. Because of the complexities of the measurement parameters, instruments and uncertainties, this standard does not cover all of the possible techniques and analysis methods.
