Specifies the format in which the measured S-parameters are saved in a SnP file.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is Auto.

RFmx automatically selects the appropriate SnP Data Format based on the value specified for SParams Format property.

If you set SParams Format to Complex or SWR or Smith Impedence or Smith Admittance or Group Delay, S-parameters are saved in the Real-Imaginary format.

If you set SParams Format to Magnitude, S-parameters are saved as either Log Magnitude-Angle or Linear Magnitude-Angle according to SParams Magnitude Units.

If you set SParams Format to Phase or Polar, S-parameters are saved as Linear Magnitude-Angle by default.
Log Magnitude-Angle 1

All available S-parameters are represented as a pair of columns - first column stores magnitude of a S-Parameter in log scale (dB) and second column stores phase of the S-Parameter in degrees.
Real-Imaginary 2

All available S-parameters are represented as a pair of columns - first column stores real part of the complex-valued S-Parameter and second column stores imaginary part.

Linear Magnitude-Angle 3

All available S-parameters are represented as a pair of columns - first column stores magnitude of a S-Parameter in linear scale (V/V) and second column stores phase of the S-Parameter in degrees.
