How to De-Embed Cables: A Practical Guide for PCB and Electronics Testing
In modern electronics design and testing, understanding how to de-embed cables is essential for obtaining accurate measurement results. Engineers often use network analyzers, oscilloscopes, and other testing equipment connected through cables. However, these cables can introduce losses, reflections, and distortions that affect the accuracy of the measurements. At BitWise Laboratories, we help clients improve signal integrity testing by applying effective de-embedding techniques. What Is Cable De-Embedding? Cable de-embedding is the process of mathematically removing the electrical effects of a cable from measurement results. Every cable introduces some level of attenuation, delay, and impedance variation. When testing high-speed circuits, these cable characteristics can significantly influence the observed performance. By de-embedding the cable, engineers can isolate the behavior of the device under test (DUT) and obtain a more accurate representation of its actual perform...
