How to generate a single pulse using PXI-4461 in Labview

Solved!
Go to solution

I need to generate a single 100ms positive going pulse using an AO on the PXI-4461, with DAQmx in Labview

I'm having trouble getting the correct time of the pulse.

 

Please Help.

 

Thanks.

Hello Skykeeper,

 

My name is Nick and I am Applications Engineer working for National Instruments.

 

It looks like you are trying to set the timing of your task.

 

The DAQmx Timing VI can be used to set the timing parameters of your task. Setting a finite sample mode and setting the last sampled value to zero will allow you to output the voltage for a finite time.

 

Can I suggest looking at the getting started with DAQmx tutorials on ni.com:

 

http://zone.ni.com/devzone/cda/tut/p/id/5434

 

They will go over the DAQmx basics and show you how to perform taks like the one you have specified. 

 

This particular section demonstrates how to output a finite wave:

Please let me know how you get on and if you have any further questions don't hesitate to ask.

 

 

Nick

Got it working, See Enclosed Diagram.

 

Thanks to NI Applications Engineer Allie Finney for the example.
