1. Definition X1 setting means the signal enters the oscilloscope without attenuation; X10 setting means the signal is attenuated by a factor of 10 before entering the oscilloscope. -v211021 2. Probe Principle The following diagram shows the equivalent circuit of the oscilloscope probe Rprobe is the input resistance of the probe, and the higher the … Read more
In the field of electronic engineering, oscilloscopes are important tools for analyzing signal characteristics. When it is necessary to observe and stabilize the waveforms from two different signal sources simultaneously, how can electronic engineers achieve this? Below are the specific steps to efficiently stabilize the display of both signals on the oscilloscope. 1. Check Signal … Read more
The oscilloscope is the most commonly used electronic measurement tool by engineers, and both verification and debugging are crucial. Verification ensures that the design meets standards, while debugging helps quickly locate and resolve faults. However, did you know that these two steps require attention to different parameters? 1. Debugging ① Waveform Capture Rate This is … Read more
Comparison of FFT Performance in Mainstream Oscilloscopes FFT, as a simple frequency spectrum testing tool, has become a standard feature in oscilloscopes. EEVBlog conducted a comparison of the FFT capabilities of mainstream oscilloscopes, selecting several common models to show their performance. Of course, the evaluation method is somewhat subjective, primarily relying on visual observation. We … Read more
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

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
