John,
The displayed error message is:
'Acquisition failed - trigger poll operation timed out - check addresses'
I have tried both, single and double precision.
The sampling rate was either determined automatically by running the
monitor or edited manually. The latter appeared to work even worse.
Sometimes it times already out while establishing GPIB connection. Best
case it runs up to tau = some 3 seconds.
I've never observed the monitor function timing out.

Hmm. Both the monitor window and acquisition loop use 5-second GPIB
timeouts, so they should theoretically behave the same. What is the exact
error message it's giving you during acquisition?
Are you using double precision, and/or a large sample size relative to the
sampling interval? I don't recall the particulars but I did see some
timeout issues depending on how much processing the Wavecrest box was being
asked to do.

John,
I'm using a NI GBIP-USB-B.
The monitor feature does not time out, just the acquisition itself.

What GPIB adapter are you using? Does the 'Monitor' feature also time
out,
or just the acquisition itself?

To be more precise, I have a working DTS-2077 and tried it a few times
with TimeLab.
TimeLab was always running fine for a few seconds but then it stopped
and displayed a timeout error.
So, what's wrong?
Adrian
