Radiated Immunity

The history and insight into how the EMC specifications and procedures evolved at one automotive original equipment manufacturer (OEM). Other present-day OEM specifications are more similar than different mostly due to the extensive reference to international standards which these OEMs have taken part in developing (e.g., EMC committees). Knowing this history should help today’s EMC practitioners, especially those new to the discipline, gain some insight into the implementation and limitations of test procedures and when to be flexible in analyzing test results.

This is the second of three articles devoted to the design, test, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.

This is the first of three articles devoted to the design, test, and electromagnetic compatibility (EMC) immunity evaluation of multilayer PCBs containing analog circuitry. In this study, there are seven design variants that all contain a similar schematic but implement different PCB layout techniques.

This month’s column is the last of three parts devoted to designing, testing, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.

RF field probes are specialized measuring instruments with unique specifications and performance characteristics. This article details the main factors to consider in selecting a probe appropriate to your testing needs.
