Today, with the rapid development of technology, various electronic and electronic peripheral related products can be seen everywhere, such as mobile phones, TVs and other electronic devices that we use most frequently. It can be said that electronic equipment has completely become a part of our life and is closely related to our life. Moreover, due to the high competition of electronic products, the speed of update and iteration is very fast, and new products emerge in an endless stream. For example, a mobile phone. Maybe the latest phone you bought will no longer be the latest in a few months. Despite this, many people do not know that the electronic products we use are developed and designed by engineers through various instruments and equipment, and one of the core members of these research and development equipment is the oscilloscope. If you are not engaged in design and development, or if we are related to the industry who know " oscilloscope ", many people may have never heard of the word "oscilloscope". Then, what is an oscilloscope for? What are its main functions and uses?
The oscilloscope , as its name suggests, literally means that it is a machine that displays waveforms, and the oscilloscope is also known as the "eye of an electronic engineer" , which is no exaggeration. The core function of the oscilloscope is to display the actual waveform of the signal under test on the screen for engineers and product development and other related test and measurement personnel to locate problems or evaluate system performance.
The oscilloscope first appeared in the 1940s. After more than 70 years of development, the types and functions of oscilloscopes have also changed a lot. The types of oscilloscopes have become diversified, with more brands and more and more functions. the stronger.
In terms of type, the common ones are: digital oscilloscope, mixed-signal oscilloscope, mixed-domain oscilloscope , etc.; there are many brands of oscilloscopes imported from abroad : Tektronix oscilloscopes , Keysight oscilloscopes (formerly Agilent oscilloscopes ) ), Rohde & Schwarz oscilloscopes , etc.; domestic ones include: Puyuan oscilloscope, Dingyang oscilloscope, Zhiyuan oscilloscope, etc. The functions and uses of oscilloscopes are also becoming more and more powerful.
oscilloscopes mainly have 5 major purposes.
1. the oscilloscope can be used to measure the voltage amplitude of DC signals and AC signals;
2., it can measure the period of AC signals and convert them accordingly.
3. signalcan be displayed with the help of an oscilloscope ;
4. If it is an oscilloscope with two channels or more, the two channels can be used for signal measurement respectively;
5. Two channels can be displayed on the screen at the same time The waveform of the signal, that is, the double trace measurement function. This function can measure the phase difference between two signals , and the difference in shape between the waveforms. These five functions and uses almost cover the needs of the test and measurement work necessary for the development and design of all our electronic products.
Therefore, it is really no exaggeration to say that the oscilloscope is called "the eyes of electronic engineers". At this point, everyone should have a basic understanding of the oscilloscope, right?
Small summary: what about the oscilloscope? What are its main functions and uses? The relevant content, Xiao Ling will first introduce it to you here, I hope it can help you.
