Rapid Trials-and-Errors Approach Based on Time-domain EMI Testing–a New Way to Speed up Product EMC Compliance

Product EMC compliance processing is expensive and time-consuming. Rapid trials-and-errors approach is proposed in this paper to reduce the costs and shorten the time achieving product EMC compliance. The time-domain EMI testing technique can meet the fast-testing requirements of the approach, and a time-domain EMI testing system developed based on a general-purpose oscilloscope and Cloud Computing is presented to further meet the low-cost testing needs of the approach. The application case shows that by applying the proposed low-cost and fast-EMI-test system, engineers in manufacturing companies can reduce the EMI of EUT through frequent and rapid trials-and-errors in short time and low cost without EMC expertise.
