Building a Curve Tracer front end to the oscilloscope is really easy and allows you to measure diodes and other two-legged components I/V performance.
Ever wondered what that mystery diode is? Here’s the way to find out 👌🏻🙂
The one shown here is based on a ‘Popular Electronics’ article and it features a current limiter as well, but simpler circuits are astoundingly easy to build, just do a search for ‘Curve Tracer Schematics’.
Hint for young players: the oscilloscope is used in XY-mode, in which, the time base controls have no effect at all - that is - on a good old analogue scope.
Digital scopes however, are sampled devices and all they really do is mimicking analogue oscilloscope behavior, including XY mode, and this is why time base has an effect.
