Thank you very much. I'd like to have a play. I sent you a private email.
Someone suggested using the DCV:DCV ratio mode to look at two references,
but I don't see this facility on the 3457A. I think the only way to compare
two of them would be to put them in series, but back-to-back to subtract
the voltages, and look at the difference on the 3457A.

It's odd there's someone selling LTZ1000A chips on eBay at $50 each.
It looks like they have been removed from PCBs with a sledge hammer - they
are heavily scratched and/or dented. The sellers seems to have sold quite a
few, yet the chips are only marginally more expensive if bought new from
