RFmxLteMXModAccResultsFetchPsschDataEvm Method
Fetches the physical sidelink shared channel (PSSCH) data EVM for ModAcc measurements.
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.

Syntax
public int FetchPsschDataEvm( string selectorString, double timeout, out double psschMeanRmsDataEvm, out double psschMaximumPeakDataEvm )
Public Function FetchPsschDataEvm ( selectorString As String, timeout As Double, <OutAttribute> ByRef psschMeanRmsDataEvm As Double, <OutAttribute> ByRef psschMaximumPeakDataEvm 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. - psschMeanRmsDataEvm
- Type: SystemDouble
Upon return, contains 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 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: Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
