Simple Curve Tracer Circuit
Useful for checking diodes, transistors, triacs, SCRs, resistors, and LEDs, this curve tracer should prove useful in the experimenter`s lab. It displays the volt-ampere characteristic of a two-ter-minal device on an oscilloscope. This is a simple block diagram of the EZ-Curve.
Current-limited AC signals are passed through both the device under test and a precision resistor to yield current and voltage readings.
