The Physics of Electromagnetic Compatibility Measurements
In a radiated electromagnetic emissions measurement, does it make a difference whether the excess cable is bundled neatly or coiled on the floor? Does it matter where an ESD simulator is grounded? Why do products that fail to meet EMC requirements in Laboratory A tend to do much better in Laboratory B? This course reviews the equipment, test set-ups and primary coupling mechanisms associated with each of the major electromagnetic compatibility tests. The goal of the course is to provide a basic understanding of the physics involved in order to make better, more meaningful and more repeatable measurements.
For each EMC test, the course reviews the test equipment, test settings and set-up parameters that affect the measurement results. Basic models of the measurements are presented that help test engineers and technicians understand exactly what is being measured. These models illustrate how sometimes seemingly minor decisions related to the test set-up can significantly affect the results of a measurement.
People who might benefit from taking this course include engineers and technicians that are new to the field of EMC and want to become familiar with EMC test procedures; as well people who have been conducting EMC tests for many years that want to develop a better understanding of the physics involved. The course can also benefit product engineers who are responsible for negotiating EMC test plans and/or ultimately ensuring that their designs will comply with EMC requirements. Course Outline
Electronic Systems Design for EMC Compliance
This course reviews the fundamental grounding, filtering and shielding concepts that all engineers can utilize to ensure the safety and reliability of their products at the lowest possible cost. Today's rapid development cycles require products to meet their EMC requirements the first time they come into the lab for testing. Board layout changes and other EMC "fixes" can significantly add to the cost of a product and/or delay its development schedule. First-pass compliance with EMC requirements starts with the circuit board layout. Printed circuit board layout is often the single most important factor affecting the electromagnetic compatibility of electronic systems. Boards that are auto-routed or laid out according to a list of “design rules” do not usually meet electromagnetic compatibility requirements on the first pass; and the products using these boards are more likely to require expensive fixes such as ferrites on cables or shielded enclosures. Taking the time to ensure that components are properly placed, transition times are not left to chance, and traces are optimally routed will generally result in products that meet all electromagnetic compatibility and signal integrity requirements on time and on budget.
This course stresses the fundamental concepts and tools that electronics engineers can employ to avoid electromagnetic compatibility and signal integrity problems. Students completing the course will be able to make good decisions regarding board layout and system design for EMC. They will also be introduced to tools and techniques for quickly reviewing designs in order to flag potential problems well before the first hardware is built and tested. Course Outline
Computer Modeling Tools for Electromagnetic Compatibility
Computer modeling has become an important part of the design process for electronic systems. This one-day training session reviews the latest computer modeling tools and techniques available to help engineers design products that comply with electromagnetic compatibility requirements. The course covers electromagnetic modeling codes, circuit solvers, rule checkers, analytical modeling tools, web-based calculators and apps. Plenty of examples demonstrating the application of various modeling tools to real-world EMC design problems are provided. Students completing the course will be aware of the tools available to them and able to make good decisions regarding the tools that are appropriate for their needs. Course Outline
