What is an Oscilloscope Used For? Understanding Functions & Applications

An oscilloscope is an essential tool for electronics professionals, students, and hobbyists. Its primary purpose is to measure and display voltage signals over time, helping users analyze signal behavior, detect problems, and verify designs.

What Does an Oscilloscope Measure?

Oscilloscopes primarily measure voltage, but they can also reveal many other characteristics of a signal, such as:

• Time and voltage values of a waveform
• Frequency of an oscillating signal
• Rise and fall times
• Noise levels and distortion

By displaying these properties on a graph, an oscilloscope helps users understand both simple and complex signals in real time.
