Common Mistakes in Choosing Oscilloscope Probes In oscilloscope measurements, the choice of probe directly affects the accuracy of the results. The probe acts as a “bridge” between the oscilloscope and the device under test (DUT), and its performance directly determines the accuracy, completeness, and reliability of the oscilloscope measurement results. However, many engineers tend to … Read more
Core Conclusion: At b=1000, liver lesions appear as high signals on both DWI and ADC images, which may seem contradictory theoretically, but can actually occur. This usually indicates that the signal attenuation behavior of the lesion at this specific value of b=1000 does not conform to a simple mono-exponential model, and its “high signal” nature … Read more
Introduction Hello everyone, I am MAI Mai Zao The reason is that a high-concurrency collection service went live, and the 100m upstream bandwidth was quickly saturated. Since this is a dedicated line and only this service is using it, it can be confirmed that it is the cause. However! This request is just a GET … Read more
MRI is a noninvasive medical imaging test that uses magnets and radio waves to create detailed images of almost every internal structure in the body. The core components of MRI include: Main Magnetic Field, in the most common cylindrical (closed) MRI devices, the direction of B₀ is parallel to the long axis of the examination … Read more
Scientifically selecting bandwidth allows your oscilloscope to “see clearly” and “measure accurately”. Have you encountered these issues? The signal source outputs perfectly, but the waveform displayed on the oscilloscope is distorted, with unclear edges and inaccurate amplitude? The problem often lies in the choice of bandwidth. In the field of electronic measurement, the oscilloscope is … Read more
In enterprise network construction, switches act as “traffic hubs,” connecting computers, servers, printers, and other devices, with their performance directly impacting office efficiency and data security. As a leading brand in the networking equipment field, Cisco switches are the preferred choice for many enterprises due to their stable performance and rich features. However, with numerous … Read more
In the process of hardware development and testing,oscilloscopes are indispensable powerful tools, but many people overlook their good partner —oscilloscopeprobes. If the probe is not selected correctly, the measured signal may be distorted, deformed, or even mislead the debugging party! Even more exaggerated, some high-end probes can sell for hundreds or even thousands of dollars. … Read more
