Gets the approximation error, in dB, in the polynomial approximation of the measured AM-to-AM characteristic of the device under test.

Syntax

Namespace: NationalInstruments.RFmx.SpecAnMX

public int GetAMToAMCurveFitResidual(string selectorString, out double value)

Remarks

This method maps to the RFmxSpecAn_AMPMGetResultsAMToAMCurveFitResidual() function in C.

Parameters

NameTypeDescription
selectorStringstring

Specifies the result name. Example: "", "result::r1". You can use the BuildResultString(string) method to build the selectorString.

valueout double

Upon return, contains the approximation error, in dB, in the polynomial approximation of the measured AM-to-AM characteristic of the device under test.

Returns

Returns the status code of this method. The status code either indicates success or describes an error or warning condition
