Both units back in-situ and powered up for about an hour......much better!
No.1 = 36.1degC
No.2 = 37.5degC

No.2 is stacked above No.1, with a 2" air space between them. There's a 2" air space below No.1 also.

Never thought to break out the C2 when it was in bits.......



Again, thanks to TiN for all the good 3458A stuff on the xdevs site.

Hi all,

I've never really done any stability tests of my own on my original 3458A (purchased from AP) but thought after fitting the new A3 board to my repaired unit I'd run some tests......and also now that I have the workshop temperature stability properly sorted.
I've also got a PDVS2 hooked up throughout (DC powered) for an additional 10V test just for fun.

It's interesting to see the new A3 board just fitted compared to the one in my original unit.

Learning more about these units every day!

Results so far after 3 days:

Ian.
