period measurement trigger rearm

[nimic]

Hello I want to measure pulse widths (8 channels on a 6602) triggered by a PFI (PFI0, f.i.). The trigger comes from my LabVIEW-application in user-definable intervals of about 1 - 5 secs. The examples provided with LV show taking a finite number of samples without a loop. But I cannot tell in advance how many samples I'll need, and I'd like to see the results before all samples are taken. I can set a trigger property to arm the trigger. But I could not find a solution to re-arm it so as to employ it in a while-loop. Most applications that are discussed here deal with counter output. Which works. But not on pulse measurement input. Thank you for your help. Michael

Hello nimic,

thank you for contacting National Instruments.

I think the example in the following link should help to solve your problem. "NI-DAQmx: Buffered Event Counting on all Counters of a 6602 or 6608"
