WriteWaveform(string, float[], float[], bool)

- 1 minute(s) read
Writes an arbitrary waveform to the NI-RFSG, starting from the position of the last data written in onboard memory.
Syntax
Namespace: NationalInstruments.ModularInstruments.NIRfsg
public void WriteWaveform(string name, float[] iData, float[] qData, bool moreDataPending)
Remarks
This method takes the I and Q vectors of a complex baseband signal as data input. If the waveform is large, use the AllocateWaveform method.
The NI-RFSG must be in the Configuration state before you call the WriteWaveform method.
Parameters
| Name | Type | Description |
|---|---|---|
| name | string | Specifies the name used to identify the waveform. This string is case-insensitive and alphanumeric, and it does not use reserved words. |
| iData | float[] | Specifies the in-phase (I) component of the complex baseband signal. |
| qData | float[] | Specifies the quadrature (Q) component of the complex baseband signal. |
| moreDataPending | bool | Specifies whether or not the data block contains the end of the waveform. Set this parameter to TrueString to allow data to be appended later to the waveform. Splitting the waveform into multiple data blocks can reduce the memory requirements of the write operation. Append data to a previously written waveform by using the same waveform in the name parameter. Set moreDataPending to FalseString to indicate that this data block contains the end of the waveform. If the waveform is already allocated, this parameter is ignored. |
Exceptions
| Type | Description |
|---|---|
| System.ObjectDisposedException | The WriteWaveform method was accessed after the associated NIRfsg object was disposed. |
