Parameters

selectorString  String

Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used. The default is "" (empty string).
Example:
""
"result::r1"
You can use the BuildResultString(String) method to build the selector string.

timeout  Double

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.

meanRmsEvm  Double

Upon return, contains the mean of RMS EVM values measured over all acquisition time slots. This value is expressed as a percentage.

maximumRmsEvm  Double

Upon return, contains the maximum of RMS EVM values measured over all acquisition time slots. This value is expressed as a percentage.

meanPeakEvm  Double

Upon return, contains the mean of peak EVM values measured over all acquisition time slots. This value is expressed as a percentage.

maximumPeakEvm  Double

Upon return, contains the maximum of peak EVM values measured over all acquisition time slots. This value is expressed as a percentage.

ninetyFifthPercentileEvm  Double

Upon return, contains the EVM value, at which no more than 5 percent of the symbols have an EVM exceeding this value. This value is expressed as a percentage.

meanFrequencyError  Double

Upon return, contains the mean of frequency error values measured over all acquisition time slots. This value is expressed in Hz.

peakEvmSymbol  Int32

Upon return, contains the symbol number in the burst measurement interval corresponding to the EVM value returned by the maximumPeakEVM parameter.
