Also, I can get a rough idea about the interchannel crosstalk visually, but how to measure it rigorously (indulge me, I know it's a noob question).

If Crosstalk is NOT defined in the datasheet look elsewhere !

I'm returning both the Siggy and the AD2 (both of them = 1000 bucks)... And I'm returning the AD2 because I like the software but the instrument itself is quite limited. Great for some specific stuff, not so for other tasks...

I'm curious about this, what have you found you aren't able to do with the AD2? not from testing the limits of it but from daily use? I have a rigol 1104z, a keysight 1102g, an owon 1022i, and the AD2, and unless I need more bandwidth or more channels, I go to the AD2 for pretty much everything else

See this: https://www.eevblog.com/forum/testgear/is-a-rigol-mso5000-overkill-for-a-hobbyist/300/

from post #311 onwards. Maybe a bit before that in order to get context.

Basically I'm unhappy with its two levels of sensitivity and doing everything else as digital zoom.

Im interested in your opinions & experiences about the use of AD2 with (relatively) low level signals.

Yeah, I've read some of that, and it's undeniable that the AD2 is not good for low level signals, but it's still a really good general purpose tool. It could be that you very often need to look at signals under 200~500mVpp and in that case, absolutely, the AD2 will not be great for that. I need to look at very small signals just ocasionally and that would be another use case for one of my other oscilloscopes, but more often than not I'm working(or playing :P) with signals above 500mVpp and under 20MHz, and for those cases, the AD2 feels great to use, not to mention that with it being not only an oscilloscope, i get even more non-oscilloscope stuff done with it, like the pattern generator and logic analyzer at the same time to work on diy digital circuits, which you can also power from the AD2 supplies, that would require a lot more space with separate instruments, so there's also that convenience. I guess i'm more curious about what you do that will require really good performance at low mV/ settings so often that the AD2 becomes a bad purchase

It's defined, but these cheap scopes differ by a considerable margin from what's declared. Sometimes they best the spec, sometimes they are well below.

florentbr’s vds1022i software is at

https://github.com/florentbr/OWON-VDS1022

I have not used it, since I do not have one of those scopes.   But the python example he gives looks very convenient to use!
