As cheap microcontrollers have given us an impressive range of test equipment trinkets to play with, it’s easy to forget some of the old standabys. A curve tracer for example, the relatively simple ...

Curve tracers are electronic test devices that are similar to oscilloscopes in many ways. Fundamentally, these instruments operate by varying a parameter, then measuring a separate one to produce data ...

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...
