What is an oscilloscope?

An oscilloscope is a test instrument used to capture and display a graph of the waveform of an electrical signal over time. For example, it can graph voltage (y-axis) versus time (x-axis) on its display.

Oscilloscopes are powerful tools for designing and testing electronic equipment. They play a very important role in determining whether system equipment components are working properly and which components are failing. They can also help you determine if newly designed components are working as expected. This can be done by analyzing signal parameters such as amplitude, period, frequency, rise time, and pulse width. Modern digital oscilloscopes can also perform mathematical operations on waveforms, such as Fourier transforms, for faster analysis.
