How to Test Transistors and FETs

To test transistors and FETs, we use the Tektronix 571 Curve Tracer.

Setting up the Curve Tracer

First thing you need to do is determine which pin your emitter, collector, and base are if you are testing a transistor, or if you are testing a FET which pins are gate, source and drain. You then insert the component you are testing into the proper slot on the curve tracer making sure each pin is going in its designated location. Once the component is properly inserted into the Curve Tracer there is a cover you can slide over the device, just in case because the components can get very hot during testing.
