here's the vi attached.
I dont think it's the loop problem. I checked it again and the program seems to be stuck at the ps3000_get_values

any help will be appreciated.

Thank you

Hi, this is Guest. I am still not able to download the attachment file.
It appears in the subject thread that there is an attachment but I am not able to find it in your post. Do I need autorisation to download the attachement? Sorry for the trouble.

Thanks,
Jason
