I've been using an old HP GPIB card in a pci slot in my 7 year old PC.
It's running win7 with the latest version of Agilent Connection Expert
and I've had the 3458 and three 3457s all hooked up at once with no
problems. I don't have any $$$$ lab programs, just hand-enter commands
and then copy/paste the data it retrieves to 'notepad'.
After every cal, I query the (cal? nnn) data, dump it and save it.
Are you saying that it would be possible to use this setup to dump the
memory data?

Poul,
I would love to know where the CALNUM value is stored.
Any idea?
Thanks.
Joe

I dumped the third
machine from a cold start and one byte was different between each dump.
If you mail those files to me, I can try to see if that bit matters.
