Electromagnetic Simulation Applied to Automotive EMC Testing

The process of designing and testing vehicles for EMC compliance can be long and expensive. Electromagnetic simulation allows potential compliance issues to be identified early in the development process, before the construction of prototypes. However, it is desirable that the simulation is able to model the test setup accurately. In this article we look at the set-up of a virtual EMC test chamber using a commercially available software and compare the simulated results to measurements from a General Motors automotive EMC test.

Shielded vs. Unshielded Square Magnetic Field Loops for EMI/ESD Design and Troubleshooting

In this article, square unshielded wire loops are compared to shielded solutions including simple techniques to build them in your lab. Some examples are included to show that unshielded loops often work as well as shielded loops in some applications, especially for injecting signals into circuits.

Prepping for EMI Testing

1408 F3 cover Like it or not, most electronic designs today are subject to formal EMI testing. So even if you are new to EMI/EMC (electromagnetic interference/compatibility), you need to understand what is involved and how to best prepare for a trip to the EMI test lab.

Lessons Learned Through Pre-certification Testing

1407 F1 cover Reading EMI test results from a test lab is very much like a radiologist reading a CT scan or MRI results. To the novice, it may seem very hard to decipher what is what, but to the trained eye, the test results provide a road map to not only the frequencies of the outages, but also an indication of what or where the outages more than likely are emanating from.
