I would like to know more about oscilloscopes, can you tell us about it?

An oscilloscope is an electronic measuring instrument that uses the characteristics of an electronic oscilloscope to convert an alternating electrical signal that cannot be directly observed by the human eye into an image and display it on a phosphor screen for measurement.

It is an indispensable instrument for observing the experimental phenomena of digital circuits, analyzing the problems in the experiment, and measuring the experimental results. The oscilloscope consists of an oscilloscope tube and power supply system, a synchronization system, an X-axis deflection system, a Y-axis deflection system, a delay scanning system, and a standard signal source.

The use of a digital oscilloscope requires an understanding of what the oscilloscope does.

The oscilloscope is the eye of the electronics engineer.

An oscilloscope is an instrument that measures signals and voltages!

The oscilloscope can directly measure the electrical signal, but as long as there is a corresponding sensor, after transformation, it can measure a variety of physical quantities, and the change curve of the instantaneous value of the measured signal can be depicted on the screen. The oscilloscope can be used to observe the waveform curves of various signal amplitudes with time, and it can also be used to test a variety of different quantities, such as voltage, current, frequency, phase difference, amplitude modulation, etc.

An oscilloscope is a very versatile electronic measuring instrument. It can transform the invisible electrical signal into a visible image, which is convenient for people to study the change process of various electrical phenomena. An oscilloscope uses a narrow, high-speed electron beam to create tiny spots of light when it hits a screen coated with a fluorescent substance.

An oscilloscope is a very versatile electronic measuring instrument. He can transform electrical signals that are invisible to the naked eye into visible images.

It is convenient for people to study the change process of various electrical phenomena. So the core function of an oscilloscope, as its name suggests, is to display the actual waveform of the signal under test on the screen for engineers to find and locate problems or evaluate system performance, etc.

And the application of oscilloscopes is not limited to the electronic field. When the appropriate sensors are installed, oscilloscopes can measure a wide range of phenomena. Sensors such as sound, mechanical pressure, pressure, light or heat.

For example, in the pressure test of the exhaust tailpipe and cylinder in the car, a special pressure sensor can be used to convert the pressure into an electrical signal and transmit it to the oscilloscope for waveform observation. Medical personnel can also use an oscilloscope to measure brain waves. Therefore, it is not an exaggeration to say that an oscilloscope is a very versatile electronic measuring instrument.

Oscilloscopes are mainly used for:

Observe the waveform change of the electrical signal

Chemical. Now it is generally used as a digital oscilloscope, which is more convenient than an analog oscilloscope, if you don't know how to use it at the beginning of the DAO, you can directly press the above 'Auto Setup' button, and you can display the waveform of the signal received from the oscilloscope. However, it is recommended to read the manufacturer's instruction manual, which can be adjusted according to your own needs.

Now the oscilloscopes on the market are not expensive, 1, 2,000 yuan of machines are a lot, but everyone recommends that even if it is a door-level oscilloscope, don't buy too rubbish, otherwise it will be really urgent to use. Tek, these are too expensive, so I won't recommend them to you. You can consider domestic production, I feel that Dingyang's SDS1102X-C is not bad, I bought it, and it can also be upgraded to 200M.

1. It can be used to measure DC.

The amplitude of the voltage of the signal and the AC signal.

2. DAO can be measured

The internal period of the AC signal, and the frequency of the AC signal is converted from this capacity.

3. The waveform of the AC signal can be displayed.

4. Two channels can be used to measure the signal separately.

5. The waveform of two signals can be displayed on the screen at the same time, that is, the double trace measurement function. This function measures the phase difference between two signals, and the difference in shape between waveforms.

The general definition is to turn an invisible electrical signal into a visible image signal, for example, to look at the waveform pull of the mains

But in fact, with various sensors, the oscilloscope can also look at some pressure signals, temperature signals, and so on.
