I got the cal data saved from a 3458A into a text file with date and time. My meter Agilent it has new boards SMD on it. So where can I get the batteries, and how do I send back the data to the meter when I lose the cal data?

I got the cal data saved from a 3458A into a text file with date
and time. My meter Agilent it has new boards SMD on it. So where
can I get the batteries, and how do I send back the data to the
meter when I lose the cal data?

For the record:

As a matter of principle, because the HP3458A is a live product,
I will not release information which gets anywhere near Keysights
copyrights.

But I have, once, restored the CALRAM data to my meter via HPIB.

That involved writing, assembling and downloading a 68k program,
which called undocumented (obviously!) version-specific functions
in the rom-image.

Never attribute to malice what can adequately be explained by incompetence.
