time sync visa input with acquired sound data

[JJac]

Hello all!

I'm pretty new to LV, but here goes:

I'm trying to collect data from a balance via VISA read (RS232), and at the same time I acquire sound via the pc sound card. I'm looking for a way to syncronise the time for the two datasets (resolution approx. 0.1 s).

During test (flicking the balance with a small spoon), my results so far indicates a offset by 0.3 s, where the sound spectrum changes before the weight increase. This is not due to any delay from the balance, as it seems to react immidiately.

I would like to be able to use the same reference clock to the two samplesets, but I'm having trouble to understand the way that "Acquire Sound.vi" works regarding recording time data.

Any good ideas for a way forward ?

Can you post your VIs. The thumb rule then asking for help in this forum. Is to post the VIs in question at the same time. Much more easy to get grasp of the problem that way. And most of us will require a VI before we help anyway. The last tip. Never post a picture of the code, as we can not debug a picture 😉

Thank You for the response.

Here follows some code...
