niFgen Set Named Waveform Next Write Position VI
- Updated2025-10-07
- 3 minute(s) read
Sets the position in the named waveform to which data is written at the next write. This VI allows you to write to arbitrary locations within the waveform. These settings apply only to the next write to the waveform specified by the Waveform Name parameter. Subsequent writes to that waveform begin where the last write ended, unless this VI is called again. The Waveform Name passed in must have been created by a call to the niFgen Allocate Waveform VI or the niFgen Clear Arbitrary Waveform VI.
Inputs/Outputs
Relative To
—
Relative To specifies the reference position in the waveform. This position and Offset together determine where to start loading data into the waveform.
Instrument Handle
—
Instrument Handle identifies a particular 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
—
Channel Name specifies the channel that this VI uses.
Waveform Name
—
Waveform Name specifies the name of the waveform. 
error in (no error)
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality. Default value: no error 
Offset
—
Offset specifies the offset from the Relative To parameter at which to start loading the data into the waveform. 
Instrument Handle Out
—
Instrument Handle Out passes a reference to your instrument session to the next VI. 
Waveform Name Out
—
Waveform Name Out passes the name of the named waveform. 
error out
—
error out contains error information. This output provides standard error out functionality. |
