loose data

[mous]

Hello,

I acquire data from 2 device 6025E by sharing the scan clock. But I have some problem to save data on DIADEM.
I loose datas. For example, with a test during 2mn30, I have only a duration of 2mn15 on DIADEM. Moreover, I loose data during all the test not only at the beginning or at the end.
I think it s a problem with the buufered acquisition but I don t know why.
To have an acquisition at 1000 Hz, my parameters are scan rate 1000, buffer size 10000 and Number of scan to read 1000.
I joined my VI in file attachements.

Thanks for your help.

Hi,

Are you losing data if you save the file as a comma separated file as well? From your program I can see that you can select if you want to store the results in DIAdem format or in text format.

It seems to me that the problem is related to the way you are acquiring data. You are doing a buffered finite acquisition in a loop. A better option will be to do a continous acquisition so there won't be gaps between loop iterations. I highly recommend you check the example built in LabVIEW Cont Acq&Chart (Buffered.
