What Is An Oscilloscope

Oscilloscope is a widely used electronic measuring instrument. It can transform invisible electrical signals into visible images, making it easy for people to study the changing process of various electrical phenomena. An oscilloscope uses a narrow electron beam composed of high-speed electrons to hit a screen coated with fluorescent material to produce small light spots (this is the principle of traditional analog oscilloscopes). Under the action of the measured signal, the electron beam is like the tip of a pen, which can depict the instantaneous value change curve of the measured signal on the screen. Using an oscilloscope, you can observe the waveform curves of various signal amplitudes over time. You can also use it to test various electrical quantities, such as voltage, current, frequency, phase difference, amplitude modulation, and so on.
An oscilloscope is an instrument used to measure the shape of alternating or pulsed current waves, consisting of an electron tube amplifier, a scanning oscillator, and a cathode ray tube. In addition to observing the waveform of the current, it can also measure frequency, voltage intensity, etc. Any periodic physical process that can become an electrical effect can be observed using an oscilloscope.
