Configures the reference waveform for the creation of reference data symbols for EVM computation.

Syntax

int32 __stdcall RFmxNR_ModAccCfgReferenceWaveformSplit(niRFmxInstrHandle instrumentHandle, char selectorString[], float64 x0, float64 dx, float32 referenceWaveformI[], float32 referenceWaveformQ[], int32 arraySize)

Parameters

NameDirectionTypeDescription
instrumentHandle[in]niRFmxInstrHandle

This parameter specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr_Initialize function.

selectorString[in]char

This parameter specifies a Selector String comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default is "" (empty string).
Example:
"signal::sig1"
You can use the RFmxNR_BuildSignalString function to build the selector string.

x0[in]float64

This parameter specifies the start time, in seconds.

dx[in]float64

This parameter specifies the sample duration, in seconds.

referenceWaveformI[in]float32

This parameter Specifies the real part of reference waveform for the creation of reference data symbols for EVM computation.

referenceWaveformQ[in]float32

This parameter Specifies the imaginary part of reference waveform for the creation of reference data symbols for EVM computation.

arraySize[in]int32

Specifies the size of the array. Set the arraySize parameter to 0 to get the size of all the arrays in the actualArraySize parameter.

Returns

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:
