PC aided transistor tester
The advantage of having a computer run gain tests on transistors is that you do not need an oscilloscope to view the characteristics. The circuit presented here is based on an earlier design, published about three years ago. This has been enhanced with a p-n-p test function, an on-board power supply, and a control program for IBM pes and compatibles.
