The trouble is that the thermistor mounts are insanely expensive and sensitive. I have a 432A -- less thermistor mount -- that I'm sort of thinking that I'll try to build something for. Just for the fun of it.
A secondary source for the 6-pin connector would be a great start. Relatively inexpensive thermistors are available. And no, I do not expect this to be precise or sensitive like the original, just proof of concept.
Well mansaxel, I was really referring to the internal 50 MHz calibration source for now. The sensor I purchased is supplied with a current calibration with all the paperwork and documentation. If I got another meter and that internal cal source (power output) compared closely to the one I have now (even using the way I was checking the first one), I'd be more confident that these sources are very stable over time. But if it didn't ... well ... yea I understand that r-hole.

Acknowledging ...
A while ago my 3458's AC card died and I was able to source a fair price repaired card, the Calibration procedure required 2 very expensive AC to DC converters, but you could work around it by using a good AC source. My 33519b was the best I had, so I gave it a go - I nearly fell over when I later sent it to HP for calibration and it passed.
I think you can get a pretty good idea by comparing your gear with each other - it soon stands out if one is 'off' 👍
(What am I saying - this is a TEA site) you of course need more gear to help the two clocks problem 😁
Right! That's the TEA spirit!
The sensor is supposed to be delivered today. These shipping companies are so overloaded they deliver more and more on Sundays now. The other day I got a package delivered in the evening. The truck that pulled up was a green Enterprise rental truck. The man that got out was dressed in Brown. My brain alerted on that sight -

He looked rather beat-down to me. I just made the comment "Enterprise rental? Is UPS out of trucks?"
He said "We have been for a while. You wouldn't believe it, it's all crazy."
