Transistor Oscilloscope

Description

The transistor oscilloscope is a versatile 3-in-1 handheld multifunction instrument that combines a digital oscilloscope, an intelligent component/transistor tester, and a DDS function signal generator into one compact device. It is specifically built for component identification, circuit troubleshooting, electronic repair, and field testing.
