RFmxNRMXModAccResults.FetchCompositeEvm Method

public int FetchCompositeEvm(
	string selectorString,
	double timeout,
	out double compositeRmsEvmMean,
	out double compositePeakEvmMaximum
)

Public Function FetchCompositeEvm ( 
	selectorString As String,
	timeout As Double,
	<OutAttribute> ByRef compositeRmsEvmMean As Double,
	<OutAttribute> ByRef compositePeakEvmMaximum 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.

compositeRmsEvmMean

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, Double) method. When you set the SetEvmUnit(String, RFmxNRMXModAccEvmUnit) method to Percentage, the measurement returns this result as a percentage.When you set the SetEvmUnit(String, RFmxNRMXModAccEvmUnit) method to dB, the measurement returns this result in dB.

compositePeakEvmMaximum

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