Course Description
Because time-to-market and budget factors often drive many of today’s high-tech designs, electromagnetic compatibility (EMC) issues often surface at the last moment in the design cycle, potentially delaying product introductions. Very often, simple pre-compliance measurements and techniques can identify issues early when the cost of implementation is substantially lower and design improvements may be made with less impact on schedules. This seminar covers the basics of EMC theory & design, plus simple bench top troubleshooting and measurement methods. It includes a number of simple techniques and tools useful in characterizing designs at various stages of development and will better prepare products for EMC qualification.

Find out how to use hands-on techniques to measure and troubleshoot EMI problems before shipping your product (and design staff) to the EMI test laboratory. We’ll review our list of “Top 10 EMC Problems” that we have seen in electronic products and discuss how to select, purchase and/or build your own near-field probes and will describe many other low-cost troubleshooting tools.

Analog, RF, Mechanical and Digital hardware design engineers will benefit from this course. A basic engineering background (BSEE or equivalent) is highly suggested.

Learning Objectives
Upon completing the course, the participant will be able to:

• Analyze, measure, troubleshoot and solve an EMC problem
• Understand the basic theory and causes of the top EMC issues: radiated emissions and electrostatic discharge
• Make or purchase simple low-cost bench top troubleshooting tools

• Perform simple evaluation and pre-qualification tests to ensure likeliness of compliance
