I think the only option for repair, out of warranty or out of repair agreement,
is 'Per Incident' which the KS website lists as $2851.00. This is a 'one
charge fits all' kind of repair price. It comes with a calibration as well.
It's what makes the repair agreement attractive as 'insurance'

Why should this be a hardware error???
It's much much more probable, that this is a natural drift phenomenon.
This is 'as found' and the 'as left' report is missing, that would tell

I also saw this, so at least, they will have adjusted this range.
Yes you're right, the ADC is the A3 board. I confused that with the A5
controller board, which is the only one which had been redesigned to SMT
components.
There's no chance to identify a refurbished or replaced board, other

But the seller told me he had been quoted 2100 Euros for repair, so I
assume Keysight thought it needs repair, not just adjustment. Also, as far
as I know, all Keysight calibration do include adjustments.
I'd like one, but don't really have the money, but I thought the price
excessive.

Dr
David,
that instrument on ebay is definitely from the agilent area, i.e. built
after 2000.
It is really ok, and does not need any repair.
Obviously, this AC range is a bit outside calibration @ 3V, 4MHz, but
that is normal after some years w/o adjustment, and not a defect at all.
Probably

my experience is that most of the eBay meters that do not give errors are
very close to spec. These old meters do not drift as much as a new meter.
If you have a good 10 volts and 10k resistor calibration is a snap...
verifying cal in not as easy. The high-frequency AC cal is more difficult.

Forgot to add. All were purchased on theBay.

There's an "interesting" $5400 buy-it-now on eBay at the minute. It's
described as "Agilent 3458A 8.5 digit Multimeter CALIBRATED".

When one reads the description, one can see it is an HP (not Agilent) 3458A,
