public int FetchSymbolChainEvmPerSubcarrierTrace(string selectorString, double timeout, int symbolIndex, ref AnalogWaveform< float > symbolChainEvmPerSubcarrier)
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Specifies a selector string comprising of the result name, segment number, and chain number. If you do not specify the result name, the default result instance is used. Example: |
| timeout | double | 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. |
| symbolIndex | int | Specifies the symbol index for which to fetch the trace. |
| symbolChainEvmPerSubcarrier | ref AnalogWaveform< float > | Fetches the chain 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.
