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 than Keithley/Tektronix. 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.
