An oscilloscope is a very widely used electronic measuring instrument. It can transform electrical signals that are invisible to the naked eye into visible images, which is convenient for people to study the changing process of various electrical phenomena. The oscilloscope uses a narrow electron beam composed of high-speed electrons to hit a screen coated with a fluorescent substance to produce a small light spot (this is the working principle of a traditional analog oscilloscope). Under the effect of the measured signal, the electron beam is like the tip of a pen, and the curve of the instantaneous value of the measured signal can be drawn on the plane. Using an oscilloscope, you can observe the waveform curves of various signal amplitudes changing with time, and you can also use it to test various electrical quantities, such as voltage, current, frequency, phase difference, and amplitude adjustment.
Then let's learn the measuring principle and quick use method of the oscilloscope together with me!
In fact, the above only describes the basic method used by the oscilloscope. In fact, there are many more functions. It can be said that this is a leapfrog invention. It allows the voltage and current signals to be displayed more intuitively in front of us for better analysis and research. If you like this article, you can save it as a quick reference manual at work, thank you!
