What you describe sounds a lot like the "ELV Komponententester"

kripton2035:
this https://www.aliexpress.com/item/1005006160645147.html
and a small supply - battery - adc board.
and a big amount of software...

It does, and I had not been aware of that product -- many thanks!

As mentioned by kripton2035, the display is a bit small. (Reassuring me that my 3.2" idea should be big enough!) And more critically, the curve tracer seems to work with a fixed +- 10V, limiting its in-circuit use. I will take a close look at their schematics though; I'm sure I can learn a few things there.

there are already aout there lots of octopus and bulky component testers...

Yes, that's the idea. I am really tempted to build something...

Why ?
Do you have a 2ch AWG ?
20V capable into HiZ ?

You already have a DSO with an excellent X-Y mode.
Is the procedure Mike used insufficient for your needs ?
