The design, development, and troubleshooting process of producing an EMC compliant device is complex and potentially expensive. In addition, the equipment for EMC pre-compliance and knowledge regarding how to implement the insights derived from that equipment pose challenges. Fortunately, real-time spectrum analyzers equipped with EMC pre-compliance software tools can provide a significant edge in pre-compliance testing that can limit costly redesigns and speed up time to market. This tech brief provides insight into this process.
