How to make a digital delay generator by using PXI 6552

[mustang1331]

I have a PXI-6552. I want to generate ten pulses from ten different DOI, all events triggered by a external trigger signal input from PFIO. The requirment is the delay which respect to the trigger signal of each pulse and the pulse width should be adjustable from the program interface. I do not know how to realize it. The platform is labview 2009. Could somebody can make a simple example for me, it will be deeply appreciated.

Hi mustang1311,

Have you looked at the Digital Waveform Editor software?  You can use it to draw your waveform and then program it to your card.  There's an evaluation version available.

Keep in mind there is a trigger response time (you can find this in the specifications for the PXI-6552).

Take a look at the DWE, and let me know if that helps.  If not, I'll need some more details about your pulses (widths and delays) to help.
