CISPR

Antennas used for EMC testing possess several characteristics which make them ideal for use in a fast-paced, production-like EMC test environment. This article will briefly describe what these characteristics are, starting with the most important parameter – antenna factor.

You’re an expert at EMC testing but, when it comes to installing, tearing down, and moving an EMC chamber, you may not have a clear understanding of all of the non-engineering tasks that go along with such an important event.

This article presents the EMC design techniques for electric vehicle powertrain modules. High voltage EMC regulations for powertrain modules are reviewed first to help understand associated design challenges. The design techniques are then demonstrated in detail to help engineers design a module that will pass the EMC requirements in the test chamber.

If you’re performing commercial radiated and conducted emissions measurements strictly by the book, you will want to utilize a measurement receiver or spectrum analyzer that fully complies with CISPR 16-1-1.

In this article, we establish design guidelines of a spread spectrum modulation circuit as it relates to CISPR 25.
