RFmxLteMXModAccResultsFetchNPuschDataEvm Method
Fetches the narrowband physical uplink shared channel (NPUSCH) data EVM for ModAcc measurements.
Use "carrier(k)" or "subblock(n)/carrier(k)" as the selector string to configure this method.
Use "carrier(k)" or "subblock(n)/carrier(k)" as the selector string to configure this method.
Namespace: NationalInstruments.RFmx.LteMX

Syntax
public int FetchNPuschDataEvm( string selectorString, double timeout, out double nPuschMeanRmsDataEvm, out double nPuschMaximumPeakDataEvm )
Public Function FetchNPuschDataEvm ( selectorString As String, timeout As Double, <OutAttribute> ByRef nPuschMeanRmsDataEvm As Double, <OutAttribute> ByRef nPuschMaximumPeakDataEvm 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. - nPuschMeanRmsDataEvm
- Type: SystemDouble
Upon return, contains the mean value of the RMS EVMs calculated on the NPUSCH data symbols over the slots specified by the SetMeasurementLength(String, Int32) method. When you set the SetEvmUnit(String, RFmxLteMXModAccEvmUnit) method to Percentage, the result is returned as a percentage, and when you set the ModAcc EVM Unit method to dB, the result is returned in dB. - nPuschMaximumPeakDataEvm
- Type: SystemDouble
Upon return, contains the maximum value of the peak EVMs calculated on the NPUSCH data symbols over the slots specified by the ModAcc Meas Length method. When you set the ModAcc EVM Unit method to Percentage, the result is returned as a percentage. When you set the ModAcc EVM Unit method to dB, the result is returned in dB.
Return Value
Type: Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
