Hello David,
Illya already made a complete and competent summary of the 3458A vs.
2002 features. So I'd just like to emphasize that the ACAL function of
the 3458A really makes the difference.
Basically, this might bring the 3458A back to its 24h specification for
each mode and range at any
We do not keep them powered up for transit.
All the meter gets more stable with age. The reference gets more stable
with burn in.
We store 3458As energised even when we do not plan to use them for a while.
Most 10 year old meters are as stable as the new meters with the high
stability option.

If one buys a used meter, one has no idea if it has been switched on very
occasional

new meter.

Well, it's the topic many can go on and on about.
As with everything there are specific cons and pros of both units, but
here are my 5c:
+ K2002 is smaller, lighter (4kg vs 10kg), less powerhungry (sometimes
it's important if you send unit for cal overseas, or take to remote site).
+ K2002 can s
I am interested to hear people's view on the relative merits of the
HP/Agilent/ Keysight 3458A vs the Keithley 2002.
I noticed that when I recently visit the standard lab for voltage at NPL,
the place was littered with Agilent 3458As, but I did not notice a single
Keithley 2002. But maybe NPL get
