RFmxLteMXModAccResults.FetchPsschDataEvmArray Method

RFmxLteMXModAccResultsFetchPsschDataEvmArray Method

Fetches the array of the physical sidelink shared channel (PSSCH) data EVM for ModAcc measurements.
Use "subblock(n)" as the selector string to read results from this method.
When you set the SetEvmUnit(String, RFmxLteMXModAccEvmUnit) method to Percentage, the method returns the results as a percentage. When you set the ModAcc EVM Unit method to dB, the method returns the results in dB.

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 FetchPsschDataEvmArray(
	string selectorString,
	double timeout,
	ref double[] psschMeanRmsDataEvm,
	ref double[] psschMaximumPeakDataEvm
)
Public Function FetchPsschDataEvmArray ( 
	selectorString As String,
	timeout As Double,
	ByRef psschMeanRmsDataEvm As Double(),
	ByRef psschMaximumPeakDataEvm As Double()
) As Integer

Parameters

selectorString
Type: SystemString
Specifies a selector string comprising of the result name, and subblock number. If you do not specify the result name, the default result instance is used. Example:
"subblock0"
"result::r1/subblock0"
You can use the BuildSubblockString(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.
psschMeanRmsDataEvm
Type: SystemDouble
Upon return, contains the array of the mean value of the RMS EVMs calculated on the PSSCH data symbols over the slots specified by the SetMeasurementLength(String, Int32) method.
psschMaximumPeakDataEvm
Type: SystemDouble
Upon return, contains the array of the maximum value of the peak EVMs calculated on the PSSCH data symbols 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.
