Semiconductor Curve Tracer Curve tracing on a scope could be made easily by KI-3020A, only a Sync. Oscilloscope is required. Characteristic curves of all types of semiconductor-transistor, FET, diodes, zener diode, SCR, TRIAC, DIAC, UJT etc. are accurately displayed. By examining these curves you can determine all of the operating characteristics of the device you are testing including gain (β), cutoff current, leakage current, output admittance and any other measurable specifications. It is far superior to the general transistor tester for checking quality. Uniquely, it is intended for testing semiconductors in production line and lab as well as making trouble shooting by technicians.- A quick checking tool for semiconductor test - Display characteristic curves for all semiconductor devices on your scope
