In electronic measuring instruments, oscilloscopes are undoubtedly a favorite among electronic engineers, as they visually display the waveform of electrical signals and generate pulse signals. When using an oscilloscope, various issues may arise, one of which is how to generate positive and negative pulse signals with different widths. How can this be done? 1. Set … Read more
Oscilloscope, as its name implies, is a machine that displays waveforms, and it is also known as the “eye of the electronic engineer.” Its core function is to display the actual waveform of the measured signal on the screen, allowing engineers to locate problems or evaluate system performance, among other tasks. Its development has also … Read more
Search WeChat Automotive Repair Handbook Many automotive repair friends have been asking how to use an oscilloscope, thinking that it is very difficult to use. In fact, once you really understand it, you will find that it is very simple to use. Over the past month (four articles), I will explain some knowledge about oscilloscopes. … Read more
01 What Is the Trigger Mode of an Oscilloscope? The “trigger” of an oscilloscope is to synchronize the oscilloscope’s scanning with the observed signal, thus displaying a stable waveform. Different “trigger modes” are required to meet various observation needs. The basic trigger modes of an oscilloscope are three: The first is “Auto Mode (AUTO)”: In … Read more
In digital circuit experiments, several instruments and meters are needed to observe experimental phenomena and results. Common electronic measuring instruments include multimeters, logic pens, ordinary oscilloscopes, storage oscilloscopes, logic analyzers, etc. The usage of multimeters and logic pens is relatively simple, while logic analyzers and storage oscilloscopes are not yet widely used in digital circuit … Read more
In our vehicle-mounted courses, we use oscilloscopes to check the current-related information of devices. Oscilloscopes are also used in embedded systems. So, what is the role of oscilloscopes in embedded systems? 01 The Role of Oscilloscopes in Embedded Systems In embedded system development, oscilloscopes play a crucial role: Signal Observation and Analysis Observe the waveforms … Read more
