What is the main purpose of an oscilloscope?

An oscilloscope is primarily used to visualize electrical signals over time. It provides a graphical representation of voltage as a function of time, allowing engineers and technicians to observe the waveform of electronic signals. This capability is crucial for analyzing various aspects of signals, such as frequency, amplitude, and shape, which are critical in diagnosing issues in circuits, assessing signal integrity, and performing other important diagnostic tasks.

By showcasing these characteristics, an oscilloscope enables users to gain insights into the behavior of electronic devices and systems under different conditions, thereby facilitating the design, testing, and troubleshooting processes in electronics. The ability to visualize how signals change over time makes it an indispensable tool in the field of electronics engineering.
