What is an Oscilloscope?
An
oscilloscope is an essential electronic instrument used to display and analyze the waveform of electronic signals. It allows scientists and engineers to visualize the variation of a signal over time, making it a critical tool in various fields, including
nanotechnology.
How Do Oscilloscopes Work?
Oscilloscopes function by capturing electrical signals through probes. These signals are then processed and displayed on a screen, typically as a two-dimensional graph with time on the x-axis and voltage on the y-axis. Advanced oscilloscopes can even measure other parameters such as current, resistance, and more.
