What Is an Oscilloscope?

An oscilloscope is an electronic test instrument that graphically displays varying signal voltages. It provides a two-dimensional graph of one or more electrical potential differences (y-axis) plotted against time (x-axis). By offering a visual representation of electronic waveforms, oscilloscopes enable users to observe changes, diagnose issues, and verify signal characteristics.
