Equipment - OscilloscopesOscilloscopes are a type of test and measurement equipment used to measure electrical signals. They are commonly used in a variety of fields, such as electronics, telecommunications, and automotive engineering. An oscilloscope typically consists of a cathode ray tube (CRT) or a flat panel display, a horizontal deflection system, and a vertical deflection system. The horizontal deflection system is used to control the movement of the electron beam across the screen, while the vertical deflection system is used to control the movement of the beam up and down the screen. This allows the oscilloscope to display a visual representation of an electrical signal over time. Oscilloscopes are used to measure various characteristics of electrical signals, such as amplitude, frequency, and rise time.
