Determine how different design modifications affect the total EMI emission in seconds
EMxpert quickly identifies emission sources from internal circuit boards, interconnecting cables, or connectors. Following a design modification, the design teams can visually document and measure reductions in the level of undesirable emissions in the design.
The spatial scan provides a detailed map of emission sources and current loops in real-time. The design team can test using either a single frequency or multiple frequencies by using the composite spatial display function. After implementing one or more design modifications, a subsequent scan provides a measurable and visually compelling comparison (as shown below).
The test measures noise without and then with a capacitor added (location in red circle)
