Discrete BJT Curve Tracer: an intuitive analog circuit analysis

You might already have seen this circuit: using an oscilloscope in X-Y mode it shows you the classic bipolar transistor IC - VCE characteristic. But how does it work? I'll try to answer this question with (almost) no math, to help you build a better analog circuits intuition.

am yet to find someone that explains circuits better than you, keep it up!

Awesome

Fantastic video. This is the sort of analysis that goes way above my head but will be very helpful for people who use this circuit for school- or even university projects. The circuit comes from an old Elektor magazine. Thank you @Indepth electronics for making this video. I will add it to the article. - Eddy Bergman.
