    Syntax

    portOrder = tdr.automaticPortOrdering(sparam)

    Description

    portOrder = tdr.automaticPortOrdering(sparam) displays the port order in the sparameters object sparam.

    example

    Examples

    Open Live Script

    Create a S-parameter object with a 4-port Touchstone file. 

    sparam = sparameters('default.s4p');

    Determine the port order of the S-parameter data. The automatic port ordering function identifies single-ended ports as differential pairs. In this example port 1 and 3 as a first differential pair and port 2 and port 4 identified as a second differential pair.

    portOrder = tdr.automaticPortOrdering(sparam)
    portOrder = 1×4

     1     3     2     4

    Input Arguments

    collapse all

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

    Output Arguments

    collapse all

    Port order in S-parameter data, returned as a vector.
