Understanding Oscilloscope Bandwidth

Recently, during interviews, I found that many hardware test engineers are completely unaware of the concept of oscilloscope bandwidth, and some with over three years of experience do not understand the concept of bandwidth. Some candidates can roughly state the conclusion: the recommended bandwidth for an oscilloscope should be 3-5 times the signal frequency. However, … Read more

How to Capture High-Speed Signals? Testing Signals That Probes Cannot Detect on Circuit Boards

With the significant improvement in the processing capabilities of communication devices, whether designing computer systems, next-generation semiconductor products, or communication systems, RF engineers must cope with increasingly higher signal rates. To enable high-speed devices to process data more efficiently, they have tirelessly invented technologies that can increase external bus bandwidth, allowing for the transmission of … Read more
