Another question is whether in the case of the FSA3011 there is the

problem of the timewrap that would not allow
the long acquisitions.

Wha's the problem?  If it's just running out of high order bits in a counting
register, I can fix that with a post-collecting pass.

You could hack the collecting software to do it.  In one sense, it's nice to
keep the collecting software clean and simple and log exactly what goes in to
it, but if you collect enough data, then the extra pass gets annoying enough
that I would take the time to fix the collection step and double check things
so I'm pretty sure it won't turn into a source of problems.

Hal,

I thank you for the answer, but I'm not a scientist like many of you
but just an amateur so I'm not able to do what you suggest.

Unfortunately I need a plug and play tool without post processing.

Hi

There are a lot of “stock” programs out there that will handle this sort of
“wrap” process. The obvious gotcah is porting them to accept the output
of the device.
