You'll find that many of the "older" members here grew up with curve tracers (we didn't have many other resources back then).
The Elektor design was / is? one of the best, that one has pretty average "curves".
There's many threads on this forum on the subject, should you have more interest.
Ahh, interesting. Always something new to learn.
Way too much, actually.
i think for same price you can buy analog oscilloscope with same functionality , component test feature
It's an 'octopus' been used for eons, google 'octopus'
Huntron Tracker is the best known commercial version of this. It's been around for 10 or 20 years.

Yes, it is a standard feature on most analog or digital Hameg scopes since late 1980s or so.

Also once made an octopus.
I know own a sort of hurton tracer copy from vu-data. And my pride is a Tektronix 576, the king of curve tracers but that is a total different class. It can do things like 1000V and 10A, you can do a lot more with a CT then most people know. Besides testing semiconductors you can measure ESR, zap nicads, charge batteries, test volt/temp coƶfficients, match components, with some additional things you can even test tubes.

If you have such a scope for $60, I think I'd like to buy it from you.
