Network Analyzer Basics: From 1998 Back to Basics Seminar

This article covers the principles of measuring high-frequency electrical networks with network analyzers, including what kind of measurements are made with network analyzers, and how they allow the characterization of linear and nonlinear device behavior. This article¹ explains RF fundamentals such as transmission lines and the Smith chart, leading to the concepts of reflection, transmission and S-parameters. All the major components in a network analyzer are reviewed, including the advantages and limitations of different hardware approaches, error modeling, accuracy enhancement, various calibration techniques, and typical swept-frequency and swept-power measurements commonly performed on filters and amplifiers.

¹Published as part of the 1998 Back to Basics Seminar (94 Slides).
