RFmxLteMXModAccResults.FetchPsschDmrsEvm Method

RFmxLteMXModAccResultsFetchPsschDmrsEvm Method

Fetches the EVM values calculated on PSSCH DMRS over the length of the measurement.
Use "carrier(k)" or "subblock(n)/carrier(k)" 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 FetchPsschDmrsEvm(
	string selectorString,
	double timeout,
	out double psschMeanRmsDmrsEvm,
	out double psschMaximumPeakDmrsEvm
)
Public Function FetchPsschDmrsEvm ( 
	selectorString As String,
	timeout As Double,
	<OutAttribute> ByRef psschMeanRmsDmrsEvm As Double,
	<OutAttribute> ByRef psschMaximumPeakDmrsEvm As Double
) 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.
psschMeanRmsDmrsEvm
Type: SystemDouble
Upon return, contains the mean value of the RMS EVMs calculated on the PSSCH DMRS symbols over the slots specified by the SetMeasurementLength(String, Int32) method.
psschMaximumPeakDmrsEvm
Type: SystemDouble
Upon return, contains the maximum value of the peak EVMs calculated on PSSCH DMRS 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.
