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 better discounts from HP/Agilent Keysight
I notice that the used prices of 3458A is higher than 2002s.
Also, are there any things ons should be looking out for when buying a
3458A or 2002? I have in the past thought an Agilent front panel was a
better than an HP one, as it would not be as old, but this is not always
true - see my comment later.
What S/N are best avoided? Does anyone have a record of S/Ns of Keighley
meters with time?
Very recently I had a somewhat scruffy HP 6674A PSU with a damaged LCD. It
cost me $50 or so to pick up a clean Agilent front panel with a new
display. The display actually turned out to be unsuitable, yet my Agilent
badged 6674A is actually a fairly old HP unit. So white my intention was
not to rebadge the PSU, that happened as a result of a legitimate reason to
get it working. So this really indicates how an old HP 3457A could be made
to look a newer Agilent one.
