Development of noise visualization system for extraneous electromagnetic waves

These days, in a rapid expansion of international electromagnetic wave regulations, EMC (electromagnetic compatibility) performance, particularly immunity to extraneous electromagnetic waves is extremely important for automotive electronic devices to secure a vehicle´s safe driving. At the same time there is now demand for automotive electronic devices to be more compact, higher-performance, and lower-cost. Therefore, it is necessary to have tools that support the engineers in taking anti-noise measures, so that immunity performance can be rapidly and accurately assured. Accordingly, we have developed a system that simulates the immunity test and visualized the noise invasion routes within the printed-circuit boards of extraneous electromagnetic waves.
