I got very lucky with my 34465A,  it is in such good condition and spot on in the DC calibration that I am not planning to play with the ADR1399. Hmm, but maybe getting a second 34465A for upgrading and comparison would not be a bad idea.
 
Messtechniker:
Is there a SCPI command for the total number
of operating hours for my 34465A? Or any
other way of determining this?

*LRN? showed a lot of SCPI commands.
But not the one I need. No hints in the manual
and the SCPI programming manual.

By the way: *LRN? is not implemented on all the other
SCPI equipment I have.

I saw that the release notes of firmware version 1.09 mentioned that a new command SYST:UPT? for querying the uptime was added, so I have reason to suspect that the feature of recording uptime did not exist in the original version, that is to say, the total uptime cannot be recorded or queried.

Or, maybe, the feature is there, but not made available to end users.
Messtechniker:
Yep. You're probably right as to no total time.
SYST:UPT? works displaying the time in days/hours/minutes/seconds
since switching on.

Time to wake this sleeping beauty again!

I'm looking to purchase the 3446MEMU 2M memory upgrade, as a private individual. Welectron are offering it for EUR 289. IIUC I will then need to register at keysight.com to get the encrypted key to load on my meter.

Has anyone done that as a private individual? Just wondering if I'll be asked for a VAT number from keysight before they will deliver the key, which would be a spanner in the works.
