Square wave analog output (USB6008)

[dalya912]

Hi,

Would anyone be able to provide me with code to generate a continuous analogue square pulse wave (pulse duration 20ms, frequency (0-5Hz) for a USB 6008? 

Would be greatly appreciated.

Have you looked at the DAQmx samples that shipped with LabVIEW?  You should find one there called Voltage - Continuous Output.  Maybe this works with your device, I'm not sure.

Thank you this is helpful. I keep getting the following error related to my clock/timing though. Do you know how I can fix this?

I can't read it.  Picture is too small.

Apologies, here you go

It means your device doesn't have an onboard clock.  It only supports software timed output.
