Oscilloscopes
An oscilloscope shows you how a signal changes over time. Digital storage scopes capture and hold waveforms for analysis, while analog scopes show a live trace with no delay.

Bandwidth
As a rule of thumb, choose a bandwidth at least five times the highest frequency you need to see. A 100 MHz scope suits signals up to roughly 20 MHz.
- 2
Channels
Two channels cover most work. Four channels help when you need to compare several signals at once, such as power electronics or digital buses.

Digital or analog
Digital storage scopes capture one-off events and offer measurements and storage. Analog scopes are simple, fast and still popular in teaching labs.
