Fetches the stream EVM per subcarrier trace for a symbol.
Use "segment(n)/stream(k)" as the selector string to read results from this method.

Syntax

Namespace: NationalInstruments.RFmx.WlanMX

public int FetchSymbolStreamEvmPerSubcarrierTrace(string selectorString, double timeout, int symbolIndex, ref AnalogWaveform< float > symbolStreamEvmPerSubcarrier)

Parameters

NameTypeDescription
selectorStringstring

Specifies a selector string comprising of the result name, segment number, and stream number. If you do not specify the result name, the default result instance is used. Example:
"segment0/stream0"
"result::r1/segment0/stream0"
You can use the BuildStreamString(string, int) method to build the selector string.

timeoutdouble

Specifies the timeout for fetching the specified measurement. 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. This value is expressed in seconds.

symbolIndexint

Specifies the symbol index for which to fetch the trace.

symbolStreamEvmPerSubcarrierref AnalogWaveform< float >

Upon return, contains the stream EVM per subcarrier trace for a symbol. For symbol indices outside the measurement interval, the trace value is NaN.

Returns

Returns the status code of this method. The status code either indicates success or describes a warning condition.
