RFmxNR_ModAccCfgReferenceWaveform
int32 __stdcall RFmxNR_ModAccCfgReferenceWaveform (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 x0, float64 dx, NIComplexSingle referenceWaveform[], int32 arraySize);
Purpose
Configures the reference waveform for the creation of reference data symbols for EVM computation.
Parameters
| Input | ||
| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxNR_Initialize function. |
| selectorString | char[] | Specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. Example: "signal::sig1" You can use the RFmxNR_BuildSignalString function to build the selector string. |
| x0 | float64 | Specifies the start time, in seconds. |
| dx | float64 | Specifies the sample duration, in seconds. |
| referenceWaveform | NIComplexSingle[] | Specifies the array of complex-valued time domain data. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively. |
| arraySize | int32 | Specifies the size of the array. |
Return Value
| Name | Type | Description | ||||||||
| status | int32 | Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred. To obtain a text description of the status code and additional information about the error condition, call the RFmxNR_GetError function. The general meaning of the status code is as follows:
