Principle of analog oscilloscope
- Jun 02, 2018 -

Oscilloscope is an electronic measuring instrument with wide application.It can transform electric signals that cannot be seen by the naked eye into visible images, which is convenient for people to study the changing process of various electric phenomena.Oscilloscope using narrow, composed of a high-speed electron beam, hit the coated with fluorescent material on the screen, it can produce tiny points of light (this is the working principle of the traditional analog oscilloscope).Under the action of the measured signal, the electron beam is like the pen tip of a pen, which can describe the instantaneous value change curve of the measured signal on the screen.Using oscillograph can observe various signal amplitude waveform curve changes over time, also can use it to test a variety of capacities, such as voltage, current, frequency, phase and amplitude, and so on.
