【測定：簡単カーブトレーサ・アダプタの試作法】 abstract This Blog explains how to make a simple curve tracer adapter. This curve tracer adapter was designed in the 1970s. So, there is no IC in it. Instead, this is a very good use of UJT. The circuit is simple, but I think it still works well today. I also dealt with how to modify the cheap oscilloscope, which is an essential part of the curve tracer. Even a
