Creating two timed digital pulses

[PK@UCSF]

Hi,

I need to create two digital output pulses on separate lines with a precise time delay between the pulses.

I am using NI-DAQmx and Microsoft Visual C (but not the Measurement Studio) and a PCI-6229 board. Could someone
please tell me the best way to do this?

Thanks,
Peter

Hi Peter,

You have a couple of options for performing this task. I recommend creating a digital waveform with your specific timing already built in to output both pulses. This operation will be more precise since you will be able to use the correlated digital i/o functionality M series boards. However, both pulses would be output on the same line.

If both pulses must be output on separate lines, then you will need to use a software trigger with your delay specified in order to output the second pulse. This operation will be software timed, so you won't have the precise timing of the first option, but you will get to output your data on separate lines. I hope that you find this information helpful.
