    Syntax

    SParameterQuality = tdr.sParamQuality(sparam)

    Description

    SParameterQuality = tdr.sParamQuality(sparam) returns the causality, reciprocity, and passivity metrics of S-parameter data specified in sparam. The quality metrics returned by the function are based on the IEEE 370 quality checker.

    example

    Examples

    Open Live Script

    Create an S-parameter object from a 4-port Touchstone file. 

    sparam = sparameters('default.s4p');

    Determine the causality, reciprocity, and passivity metrics of the S-parameter data based on the IEEE 370 quality checker. 

    tdr.sParamQuality(sparam)
    ans = struct with fields:
         CausalityQuality: "Good"
      CausalityPercentage: 99.5084
       ReciprocityQuality: "Acceptable"
    ReciprocityPercentage: 99.6269
         PassivityQuality: "Good"
      PassivityPercentage: 100

    Input Arguments

    N-port S-parameters, specified as an sparameters object.

    Output Arguments
