Are you using the DT-VPI add-on for HP-VEE?
If not, I recommend it.

As for your problem, I had something similar with a DT302 using DT-VPI
and it was solved by a more careful accessing of A/D.
Basically, I had the system creating more data than I was able to read
and the buffer overflowed.
My cure was to have a "Start Acquisition" command before I got my buffer
of data and then once I received it, I called a "Stop Acquisition".
This made sure that the A/D wasn't putting data into buffer's that I
wasn't able to read.

Hope this helps.
