ViStatus __stdcall niRFSGPlayback_DownloadUserWaveformComplexF32 (ViSession rfsgSession, ViConstString rfsgWaveformName, ViReal64 t0, ViReal64 dt, NIComplexNumberF32 waveform[], ViInt32 waveformSize, ViInt32 burstPresent);
Purpose
Normalizes the input waveform and writes it into the NI RF vector signal generator. This VI computes the peak to average power ratio (PAPR) using the bursts in the waveform, stores the PAPR, sample rate, waveform size, and runtime scaling value of -1.5 dB in the NI-RFSG waveform database.
Parameters
| Input | ||
| Name | Type | Description |
| rfsgSession | ViSession | Identifies the instrument session. rfsgSession is obtained from either the niRFSG_init function or the niRFSG_InitWithOptions function. |
| rfsgWaveformName | ViConstString | Specifies the name used to write the waveform to the NI-RFSG device memory. |
| t0 | ViReal64 | Specifies the start time of the given input waveform. |
| dt | ViReal64 | Specifies the time interval between the samples in the given input waveform. |
| waveform | NIComplexNumberF32[] | Specifies an array of the complex single waveform clusters to be downloaded to the device. |
| waveformSize | ViInt32 | Specifies the size of the waveform array. |
| burstPresent | ViInt32 | Specifies whether the burst is present in the given waveform. |
Return Value
| Name | Type | Description | ||||||||
| status | ViStatus | 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 niRFSGPlayback_GetError function. The general meaning of the status code is as follows:
