RFmxLteMXModAccResults.FetchSpectralFlatnessTrace Method

RFmxLteMXModAccResultsFetchSpectralFlatnessTrace Method

Returns the spectral flatness, upper mask, and lower mask traces. Spectral flatness is the magnitude of equalizer coefficients at each allocated subcarrier. Lower and upper masks are derived from section 6.5.2.4.5 of the 3GPP TS 36.521 specification.
Use "carrier(k)" or "subblock(n)/carrier(k)" as the selector string to read results from this method.

Namespace:  NationalInstruments.RFmx.LteMX

Syntax

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
Specifies the data for a real waveform including the start, delta, and actual values.
spectralFlatnessLowerMask
Type: NationalInstrumentsSpectrumSingle
Specifies the data for a real waveform including the start, delta, and actual values.
spectralFlatnessUpperMask
Type: NationalInstrumentsSpectrumSingle
Specifies the data for a real waveform including the start, delta, and actual values.

Return Value

Type: Int32
Returns the status code of this method. The status code either indicates success or describes a warning condition.
