DAQmx Create Timing Source (Frequency) (G Dataflow)

Last Modified: September 18, 2017

Creates a timing source that sends ticks to a Timed Loop at a constant frequency.

NI-DAQmx uses the counter you specify to generate the signal for the timing source.



counter specifies the name of the counter to use for the timing source. The DAQmx physical channel constant lists all physical channels, including counters, for devices installed in the system.

You also can wire a string that contains a name of a counter to this input.



frequency specifies in hertz the frequency at which you want to send ticks to the Timed Loop.


error in

error in describes error conditions that occur before this node runs. This input provides standard 'error in' functionality.


timing source name

timing source name is the name to assign to the timing source this node creates.


timing source out

timing source out is the name of the timing source this node creates. Wire this output to the source input of the Input Node of a Timed Loop.

If you specified a name for the timing source in the timing source name input, this output contains the same name. If you did not specify a name for the timing source, NI-DAQmx creates a name and sets this output to that name.


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
