RFmxDemodMXDDemodResults.FetchIQImpairments Method

public int FetchIQImpairments(
	string selectorString,
	double timeout,
	out double meanIQGainImbalance,
	out double meanQuadratureSkew,
	out double meanIQOriginOffset
)

Public Function FetchIQImpairments ( 
	selectorString As String,
	timeout As Double,
	<OutAttribute> ByRef meanIQGainImbalance As Double,
	<OutAttribute> ByRef meanQuadratureSkew As Double,
	<OutAttribute> ByRef meanIQOriginOffset As Double
) As Integer

Parameters

selectorString  String

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

timeout  Double

Specifies the time, in seconds, for which the method waits for the measurement to complete. A value of -1 specifies that the method waits until the measurement is complete.

meanIQGainImbalance  Double

Upon return, contains the measured ratio of I gain to Q gain, in dB.

meanQuadratureSkew  Double

Upon return, contains a measure of I and Q components in the signal that are not perfectly orthogonal.

meanIQOriginOffset  Double

Upon return, contains the offset, in dB, from the ideal location of the constellation origin.
