Build a simple Transistor Curve Tracer using an Arduino and Processing You always get to that point, when teaching something easy, that you start to cross over into the realm of the slightly more complicated. 25V and VDS is swept again. Paul also added a DPDT switch to toggle and compare two devices under test. This circuit is under:, meter counter, meters, simple curve tracer circuit l14760 Useful for checking diodes, transistors, triacs, SCRs, resistors, and LEDs, this curve tracer should prove useful in the experimenter`s lab. representatives of AC hysteresis loop tracers some require the ring form of samples, while others can be used with thin films, wires or even rock and mineral samples. A Curve Tracer displays the voltage vs current characteristic curves of electronic devices such as transistors and diodes. Fantabulously expensive as well. 3 Generating an I-V curve for a resistor 1. You should be able to watch the primary capacitors charge up. It is used for testing electronic components and circuitry, and works in conjunction with an oscilloscope in X-Y mode (where the X and Y axes indicate the voltages on each channel and no time base is involved).
