What is an oscilloscope?
Oscilloscope is used to measure the shape of alternating current or pulse current wave. It is composed of tube amplifier, scanning oscillator and cathode ray tube. It can be used to observe the form of current and measure the frequency , voltage intensity, etc., it can be used for the observation of periodic physical processes that can become electrical effects.
The oscilloscope is a multifunctional measuring instrument that can draw the time and value of the continuously changing signal of the circuit, and is often used as an analysis tool for measuring circuits and signals. It is mainly divided into two categories: analog oscilloscope and digital oscilloscope. The analog oscilloscope uses the electron beam emitted by the electron gun to focus and then reaches the phosphor screen to form an image; the digital oscilloscope realizes it through software, data acquisition and A/D conversion. Digital oscilloscopes can also be divided into different types such as digital storage oscilloscopes, digital phosphor oscilloscopes, and sampling oscilloscopes. Using an oscilloscope for measurement equipment can more effectively analyze signal characteristics in circuits, locate faults, and more.
OSP1102 Digital Oscilloscope
The basic structure of the oscilloscope consists of a display circuit and a control circuit, in which the display circuit It also includes four parts: oscilloscope tube, electron gun, deflection deflection system and fluorescent screen. The oscilloscope tube can continuously convert the changing voltage into a display screen, so as to realize the visual detection of the voltage change.
The principle of digital oscilloscope is to use A/D converter to convert analog signal into digital signal, then use software programming to analyze digital signal, and then convert digital signal into analog signal, It is reflected on the screen to display the waveform diagram, and can also perform various data measurement or analysis.
Digital Oscilloscope: An essential tool for acquisition, triggering, display, and analysis techniques. The emergence of digital oscilloscopes has changed traditional measurement techniques and provided reliable tools for engineers to quickly and accurately solve measurement challenges. The unique advantages of digital oscilloscope make it widely used in front of engineers, but its improper use will cause large measurement errors, which will affect the effectiveness of test task completion.
