RFmxNRMXModAccResults.FetchSpectralFlatnessTrace Method

public int FetchSpectralFlatnessTrace(
	string selectorString,
	double timeout,
	ref Spectrum<float> spectralFlatness,
	ref Spectrum<float> spectralFlatnessLowerMask,
	ref Spectrum<float> spectralFlatnessUpperMask
)

Public Function FetchSpectralFlatnessTrace ( 
	selectorString As String,
	timeout As Double,
	ByRef spectralFlatness As Spectrum(Of Single),
	ByRef spectralFlatnessLowerMask As Spectrum(Of Single),
	ByRef spectralFlatnessUpperMask As Spectrum(Of Single)
) As Integer

Parameters

selectorString

Type: SystemString
Specifies a selector string comprising of the result name, subblock number, and carrier number. If you do not specify the result name, the default result instance is used. Example:
"subblock0/carrier0"
"result::r1/subblock0/carrier0"
You can use the BuildCarrierString(String, Int32) method to build the selector string.

timeout

Type: SystemDouble
Specifies the timeout for fetching the specified measurement. This value is expressed in seconds. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the method waits until the measurement is complete.

spectralFlatness

Type: NationalInstrumentsSpectrumSingle
Upon return, contains the spectral flatness.

spectralFlatnessLowerMask

Type: NationalInstrumentsSpectrumSingle
Upon return, contains the lower mask of the spectral flatness.

spectralFlatnessUpperMask

Type: NationalInstrumentsSpectrumSingle
Upon return, contains the upper mask of the spectral flatness.
