An oscilloscope is an electronic measuring instrument with a wide range of uses. It can convert invisible electrical signals 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 fluorescent substances to produce tiny light spots. Under the action of the signal under test, the electron beam is like the tip of a pen, which can draw the change curve of the instantaneous value of the signal under test on the screen. The oscilloscope can be used to observe the waveform curves of various signal amplitudes changing with time, and it can also be used to test various electric quantities, such as voltage, current, frequency, phase difference, amplitude modulation, etc.

The role of the oscilloscope:
1. It can measure the voltage amplitude of DC signal and AC signal
2. It can measure the period of the AC signal and convert it to the frequency of the AC signal.
3. It can display the waveform of AC signal.
4. Two channels can be used for signal measurement respectively.
5. The waveforms of two signals can be displayed on the screen at the same time, that is, the function of dual trace measurement. This function measures the phase difference between two signals, and the difference in shape between waveforms.

The price of the oscilloscope is generally not cheap, the correct use and maintenance of the oscilloscope can not only reduce the damage of the instrument, but also prolong the service life of the oscilloscope.
The oscilloscope needs a battery to maintain it, so I recommend TEFOO ENERGY’s standard lithium battery, which is convenient for operators to carry out mobile indoor and outdoor operations, and providing continuous, efficient and stable mobile power supply has become a prerequisite for the normal operation of such equipment. Maximum protection. The solution uses high-performance batteries, so that the entire battery has the characteristics of high energy ratio, light weight, small size, high cycle life, high safety, and high consistency. The battery is very convenient to use, and the original battery can be directly replaced on site.
