A variety of functions of Dingyang Technology oscilloscope can play an important role in digital circuit testing, especially high-bandwidth and high sampling rate products. Even when measuring high-frequency signals, it can ensure the true restoration of signals and capture high-speed transient signals, so as to quickly and accurately find and locate problems. It can capture and analyze abnormal events and specific events, measure multiple digital signals simultaneously, analyze parameters of digital signals and decode serial bus signals, analyze and evaluate the jitter characteristics of signals in digital communication systems, and improve system performance. By reasonably setting the parameters of oscilloscopes and using its advanced functions, the efficiency and accuracy of digital circuit testing can be greatly improved.
