niFgen Write Named Waveform VI
Installed With: NI-FGENBy default, the subsequent call to the niFgen Write Named Waveform (poly) VI continues writing data from the position of the last sample written. The write position and offset can be set using the niFgen Set Named 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 Named Waveform (DBL)
Writes floating-point data to the named 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 Name specifies the name of the waveform. |
 |
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 Name Out passes the name of the named waveform. |
 |
error out contains error information. This output provides standard error out functionality. |
niFgen Write Named Waveform (I16)
Writes binary data to the named 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 the named 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.
