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.

meanRmsCompositeEvm

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

meanFrequencyError

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

peakCompositeEvmSymbolIndex

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

peakCompositeEvmSubcarrierIndex

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

peakCompositeEvmSlotIndex

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