niFgen Write Waveform (poly) VI
Installed With: NI-FGENWrites data to the waveform in onboard memory.
The Waveform Handle passed in must have been created by a call to the niFgen Allocate Waveform VI or the niFgen Create Waveform (poly) VI. By default, the subsequent call to the niFgen Write Waveform (poly) VI continues writing data from the position of the last sample written. You can change the write position and offset using the niFgen Set Waveform Next Write Position VI. If streaming is enabled, you can write more data than the allocated waveform size in onboard memory. Refer to the Streaming topic for more information about streaming data.
niFgen Write Waveform (DBL)
Writes data to a waveform in onboard memory. If streaming is enabled, you can write more data than the allocated waveform size in onboard memory. Refer to the Streaming topic for more information about streaming data.
 |
Instrument Handle identifies your instrument session. Instrument Handle is obtained from the niFgen Initialize VI, niFgen Initialize With Options VI, or the niFgen Initialize With Channels VI. |
 |
Channel Name specifies the channel that this VI uses. |
 |
Waveform Handle specifies the handle of the arbitrary waveform previously allocated with the niFgen Allocate Waveform VI. |
 |
Waveform Data specifies the array of data you want to load into the waveform. You must normalize the data points in the array to be between -1.00 and +1.00. |
 |
error in describes error conditions that occur before this node runs. This input provides standard error in functionality. Default value: no error |
 |
Instrument Handle Out passes a reference to your instrument session to the next VI. |
 |
Waveform Handle Out returns the handle that identifies the waveform. |
 |
error out contains error information. This output provides standard error out functionality. |
niFgen Write Binary 16 Waveform
Writes binary data to a waveform in onboard memory. If streaming is enabled, you can write more data than the allocated waveform size in onboard memory. Refer to the Streaming topic for more information about streaming data.
This instance can also write complex data to a waveform in onboard memory on devices with the OSP Enabled property set to TRUE and the Data Processing Mode property set to Complex. To write complex data, you must interleave the I/Q pairs or use the Complex DBL or Complex WDT instances of this VI.
