a type of electronic test instrument which allows observation of constantly varying signal voltages, especially very fast changes in voltage over time. The oscilloscope can show information which a simple multimeter cannot. The display usually shows as a two-dimensional plot of one or more signals as a function of time. Non-electrical signals (such as sound or vibration) can be converted to voltages and displayed.

- Often modern digital circuit voltages measured by an oscilloscope are small, but with any measurement of electricity, one should take care to avoid any potential shock.
- Analysis of circuits from Cathode Ray Tube televisions is extremely dangerous and NOT a beginner’s activity. Thousands of volts are involved.
