DAQmx Timing (Burst Export Clock) (G Dataflow)
Configures when the DAQ device transfers data to a peripheral device, using the onboard Sample Clock of the DAQ device to control burst handshake timing, and exporting that clock for use by the peripheral device.

task in
task in is the name of the task that the operation applies.
sample clock rate
sample clock rate specifies in hertz the rate of the Sample Clock.
sample clock output terminal
sample clock output terminal specifies the terminal to which to export the Sample Clock.
sample clock pulse polarity
sample clock pulse polarity specifies the polarity of the exported Sample Clock.
| Name | Description |
|---|---|
| Active High | Active high. |
| Active Low | Active low. |
error in
error in describes error conditions that occur before this node runs. This input provides standard 'error in' functionality.
sample mode
sample mode specifies if the task acquires, or generates samples continuously, or if it acquires or generates a finite number of samples.
| Name | Description |
|---|---|
| Continuous Samples | Acquire or generate samples until DAQmx Stop Task runs. |
| Finite Samples | Acquire or generate a finite number of samples. |
| Hardware Timed Single Point | Acquire or generate samples continuously using hardware timing without a buffer. Hardware timed single point sample mode is supported only for the sample clock and change detection timing types. |
samples per channel
samples per channel specifies the number of samples to acquire, or generate for each channel in the task, if sample mode is Finite Samples. If sample mode is Continuous Samples, NI-DAQmx uses this value to determine the buffer size. This node returns an error if the specified value is negative.
pause when
pause when specifies whether the task pauses while the trigger signal is high or low.
| Name | Description |
|---|---|
| High | Pause the task while the trigger signal is high. |
| Low | Pause the task while the trigger signal is low. |
ready for transfer event active level
ready for transfer event active level specifies the polarity of the Ready for Transfer Event.
| Name | Description |
|---|---|
| Active High | Active high. |
| Active Low | Active low. |
task out
task out is a reference to the task after this node runs.
error out
error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, error out describes the error status that this node produces.
Where This Node Can Run:
Desktop OS: Windows
FPGA: LabVIEW NXG does not support FPGA devices
Web Server: Not supported in VIs that run in a web application
