What are S-parameters?
vector network analyzer
 
S-parameters are the electrical characteristics of a signal in a complex network. It is also known as scattering parameters and mostly used in RF network and applications. Vector Network Analyzer is used to measure and analyze signal behavior of S-parameters. The signal behavior can be observed as gain, return loss, VSWR, reflection coefficient and group delay etc.
