NI 6602 buffered pulse width and buffered period measurement with 2 counters synchronized during a defined time "

[discovery]

it is OK for 2 counters if I count a defined number but I would like the values during a time for example 10 s .It seems that the acquisition is not complete.Is a problem of circular buffer, time out error .....?

Hi:

I am assuming that you are using 2 counters to generate a finite pulse train for 10 seconds and are using this pulse train to gate the other counter. If this is your setup, you should not have a problem in retrieving the correct number of readings.

You can monitor to the backlog and number read by wiring indicators to Read Buffer VI. Please also look at the Count Buffered Edges (DAQ-TIO).vi examples to learn how you can correctly set up a buffered counter acquisition.

To open up the example, click on Help -> Find Examples -> Hardware Input & Output -> Traditional DAQ -> Counter -> NI-TIO.

Thank you of your answer, but I think that I badly presented problem: I have to measure the width of the impulses of a signal and the period of another signal during a given time and get back the synchronous data of these 2 signals.
