They do.

My mixed system (A6302 from the US, AM503A from the Czech Republic, TM502 from Germany) works without any problems. 8)

Have you tried a stability test over time?
All my quick tests looked good, and the stability test was decent with the newer probe. After I replace the larger filter caps I'm going to try again after a nice warmup. As I've said before, this is for entertainment and education. I could have left it alone and it would be fine for measuring. 😉
KungFuJosh:
Ya know, I thought replacing some caps might help, but I wasn't expecting this result. 😎
So far, I only replaced 4 caps (2 each):
50V 2000uF Old: 60mΩ ESR New: 13mΩ ESR
50V 1000uF Old: 120mΩ ESR New: 11mΩ ESR
That looks slightly better than the test in reply #181.
Thanks,
Josh

You can see the quantization in the blue trace, so the red trace surely has different averaging applied on the scope.

The red trace is an SDM3055X-E. The blue trace is the SDS2404X HD. The settings are identical between both stability tests, except I think the 2nd test sampled more frequently (log rate in TC).
I attached both tests to this reply to make it clearer.
