Syntax
public int FetchEvmPerSymbolTrace( string selectorString, double timeout, ref AnalogWaveform<float> rmsEvmPerSymbol )
Public Function FetchEvmPerSymbolTrace ( selectorString As String, timeout As Double, ByRef rmsEvmPerSymbol As AnalogWaveform(Of Single) ) 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. - rmsEvmPerSymbol
- Type: NationalInstrumentsAnalogWaveformSingle
Upon return, contains the starting OFDM symbol position corresponding to Meas Slot Offset parameter.
Return Value
Type: Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
