I had a Solartron 7081 that I had sent to AMETEK for repair and calibration.
I used it as a ‘transfer’ standard. My AC source was a 3326A fed via Coax
to a 50 ohm terminator read first by the Solartron then fed to the 3458A and
the ‘Solartron value’ entered into the 3458A. The 10 VDC was a 731B and the
10K resistor was a Leeds and Northrup 10 K resistor, both read by the 7081,
and then feeding those measurements into the 3458A. I was amazed at how
well it worked.
Now I have a Fluke 5100B that should be much better at the AC stuff and not
bad at the rest of it as well. Although the Fluke 5100B is only 5 ? digits,
it is fairly stable and should be a good ‘source’ to be read by the 3458A or
the 7081, as long as everything is ‘warmed up’ and you are quick, giving it
little time to change.

When getting an Agilent calibration of the 3458A, you get 'As Received'
and
'As Completed' data. Very helpful to me in that the only two points my
'House CAL' of the one 3458A failed were the two 'midrange' AC Voltage
values. All else 'PASSED'.
What do you use as a "House CAL" that is almost good enough for the
8.5 digit 3458A?
That's a seriously accurate (and seriously expensive), multi-meter.
