This struck me as a bit odd - an EU3458A 8.5 digit multimeter. I thought at
first that perhaps it had been re-engineered to use lead-free solder, but
on reading the description, that's not the case.

The Keysight website says
I can't see what is the point of giving it a new part number. But at least
is dismisses some of the myths that used 3458As would go up in value in the
EU, since it would be impossible to buy a new one.
I'm puzzled why option 002, an upgrade of memory to 128 kb, is still an
option one has to pay for. With the cost of RAM what it is now, I'm
suprised the memor is not not standard. Perhaps the only way Keysight can
provide 128 kb is to use old chips, as new ones are too large!

Sorry, I mean option 001. Option 002 is the higher stability 4 ppm/year
reference, which naturally costs more.
