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.

meanRmsCompositeEvm

Type: SystemDouble
Upon return, contains the array of the mean value of the RMS EVMs calculated on all configured channels over the slots specified by the SetMeasurementLength(String, Int32) method.

maximumPeakCompositeEvm

Type: SystemDouble
Upon return, contains the array of the maximum value of peak EVMs calculated on all configured channels over the slots specified by the ModAcc Meas Length method.

meanFrequencyError

Type: SystemDouble
Upon return, contains the array of the estimated carrier frequency offset averaged over the slots specified by the ModAcc Meas Length method.

peakCompositeEvmSymbolIndex

Type: SystemInt32
Upon return, contains the array of the symbol index where the ModAcc maximum peak composite EVM occurs.

peakCompositeEvmSubcarrierIndex

Type: SystemInt32
Upon return, contains the array of the subcarrier index of the Max Pk Composite EVM method.

peakCompositeEvmSlotIndex

Type: SystemInt32
Upon return, contains the array of the slot index where the ModAcc maximum peak composite EVM occurs.
