Hey, disregard my last two posts. I was able to find some answers from that other forum. That one seems to be a lot more active. I appreciate all your help.

Is there a way to download that program in LV 8.0? That is what I am using and it gives me an error everytime I try to download it??

Do you know if this will work ok at 40khz though?

YOU ARE AWESOME!!! Thank you so much. That looks exactly like what I need! I guess I could have found that, had I done a little more research.

Ha, ya I am trying to get as many ideas as I can. The sync is at 40 khz. I believe I am sampling at 1M. And yes, the output does continue to skew relative to the sync.

I am using a PCI slot DAQ and just then standard TI switch board interface card to talk to the DAQ for the inputs and outputs.

Alright, here is a really rough sketch of what I am trying to accomplish... I have that INPUT sync, and I am trying to create that output signal. I will post my code in the morning. Its on a different computer. Thanks so much!

the only code I have thus far, is the signal generator and the signal analysis. The rest is kaput so I deleted it to attempt a different way. Is what I was doing, was send this signal through a peak detector and send it to my loop. This is where I am having the most trouble I can't seem to output the short pulse. And I also am having troubles jumping through the segments of each square wave.

Ok, so I am having major issues. I have spent several hours attempting this, seemingly simple problem... This is what I am trying to do: I am trying to create a program that receives a square wave synch input at 40khz. From here, I am trying to detect the beginnning of the positive flat portion of the square wave. From here, I need a for loop that recognizes the beginning of the positive flat portion, then outputs a short pulse at this point. However, there is a trick.... I need the first output pulse to be right at the beginning, then the second output pulse to be output at about 1/4 of the way through the positive portion of the square wave, then the third to be about 1/2 way through... and so on and so on. Any help would be great. I know there is something that I missing big time. Because I really should be able to do this in about 10 minutes.
