Product description:
An oscilloscope is a very versatile electronic measuring instrument. It can transform invisible electrical signals into visible images, which is convenient for people to study the changing process of various electrical phenomena. Oscilloscopes use a narrow beam of high-speed electrons to strike a phosphor-coated screen to produce tiny spots of light (this is how traditional analog oscilloscopes work). Under the action of the measured signal, the electron beam is like the tip of a pen, which can depict the change curve of the instantaneous value of the measured signal on the screen. Using an oscilloscope, you can observe the waveforms 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, amplitude modulation, and so on.
