Some years ago, one of the fundamental electronic instruments was the laboratory curve tracer. A CRT display would sweep out terminal behavior (current versus voltage) from which you could derive ...
The CTR-101 Curve Tracer from Saelig Company, Inc. plots device characteristics for diodes, transistors, MOSFETs, JFETs, and other LF and RF semiconductors, or demonstrate the linearity of resistive ...
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 ...
