Concept of Logic Analysis The logic analyzer is also a very commonly used instrument, just like the oscilloscope, and is one of the classic instruments for digital design and measurement. When measuring digital circuits, when should an oscilloscope be used? Generally, an oscilloscope can be used when precise parameter information (such as time intervals and … Read more
The logic analyzer has always been shrouded in mystery. While most R&D personnel are very familiar with oscilloscopes, they may still be somewhat unfamiliar with logic analyzers. Perhaps you guessed it is an expensive, large instrument with a bulky chassis. Whether right or wrong, at least that’s what I thought when I was in college. … Read more

RF (Radio Frequency) and Mixed Signal PCB Layout Guidelines RF (Radio Frequency) and Mixed Signal (Analog & Digital Mixed Signals) PCB design requires special attention to issues such as signal integrity, noise control, and electromagnetic interference (EMI). Their layout differs from ordinary digital PCB design because they involve high-speed signals, the coexistence of sensitive analog … Read more
In the process of PCB design and manufacturing, batch chamfering of traces is an important step that helps to enhance the electrical performance and mechanical strength of PCBs, while also facilitating operations during production and assembly.We need to pay attention to some key points of batch chamfering of PCB traces: 01 Purpose of Chamfering • … Read more
What Is Impedance? Isn’t It The Same As Resistance? Regarding impedance (Impedance), I have found that many newcomers to this concept often confuse it with resistance (Resistance). This confusion may arise because both terms contain the character for “resistance” in Chinese, and both units are expressed in Ω. Additionally, impedance and resistance are related to … Read more
Introduction With the growing demand for networking, the issue of gigabit Ethernet speed has garnered significant attention. This article analyzes the low actual speed situation, detailing reasons such as poor wiring, and provides effective methods for improving speed and stability from both hardware aspects like equal-length wiring and impedance matching, as well as software debugging … Read more
As medical wearable devices and personal electronics continue to trend towards miniaturization, the requirements for the electronic components integrated within them are becoming increasingly stringent. In particular, medical-grade wearable devices must not only be smaller, lighter, and thinner in physical dimensions but also meet critical metrics essential for medical applications, including high precision, high reliability, … Read more
PCB Copper Pour refers to the area filled with copper in a PCB layer. This layer can be on the top, bottom, or any internal layer of the PCB, and PCB copper pour can be used for grounding, reference, or to isolate specific components or circuits from the rest of the elements on that layer. … Read more
