Re: Trying to synchronize switching times VERY precisely

The Windoze technical info states that they do not guarantee timing better than 100ms with the system clock. You're right, that generally it's much better than that, but I have seen pauses in my VIs that vary up to 25ms (using a take time before the loop and then check time after the loop). My old

Hello Kelly! Essentially, it sounds like you are wondering how accurate the wait functions in LabVIEW are. The timing accuracy of a Windows-based computer is typically 1ms, so at first glance the answer to your question is approximately +/- 1ms. There are several things that can affect the timin

I have a VI that switches between two voltage states and resides in one state or another according to a wait function. I need this switching to be extremely precise. For example, if I want the first voltage state to be held for 200ms, it MUST be as close to that as possible. How can I figure out
