RFmxLteMXModAccResults.FetchEvmPerSubcarrierTrace Method

RFmxLteMXModAccResultsFetchEvmPerSubcarrierTrace Method

Returns the EVM of each allocated subcarrier averaged across all the symbols within the SetMeasurementLength(String, Int32) method.
Use "carrier(k)" or "subblock(n)/carrier(k)" as the selector string to read results from this method.

Namespace:  NationalInstruments.RFmx.LteMX
Assembly:  NationalInstruments.RFmx.LteMX.Fx40 (in NationalInstruments.RFmx.LteMX.Fx40.dll) Version: 24.5.0.49283 (24.5.0.49283)

Syntax

public int FetchEvmPerSubcarrierTrace(
	string selectorString,
	double timeout,
	ref AnalogWaveform<float> meanRmsEvmPerSubcarrier
)
Public Function FetchEvmPerSubcarrierTrace ( 
	selectorString As String,
	timeout As Double,
	ByRef meanRmsEvmPerSubcarrier As AnalogWaveform(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.
meanRmsEvmPerSubcarrier
Type: NationalInstrumentsAnalogWaveformSingle
Upon return, contains the mean value of the RMS EVMs calculated on all configured channels over the slots specified by the ModAcc Meas Length method.

Return Value

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