Testing

Even if you are not involved in the practice of the measurement of antennas but have a passing interest and would like to learn more, this is the standard to read. Doing so will quickly get you up to speed, saving you many hours of unnecessary research and much confusion.

This two-part article provides an overview of current automotive EMC standards and the intricacies of chamber testing automotive systems and components.

Product standards, such as IEC 62368‑1 for ITC equipment, struggle to keep up with technology changes, even when they are designed to be adaptable – such as this hazard-based standard. Unexpected consequences can develop with the introduction of disruptive technology that takes advantage of a seeming loophole in a standard and move forward without getting a full evaluation under the standard. Fault managed power systems, such as PoE, push the standard in getting proper evaluation. This paper is a case study including a detailed proposal as to how to address an issue such as this within the standard.

Manufacturers should understand product liability law and consider it pre-sale when they design and manufacture their products and after sale when they deal with potential product safety problems reported to them by consumers. Doing so will result in safer products and, if there is a lawsuit, a better defense.

To provide in-depth coverage of ESD testing methods, in this article, we look at another type of ESD testing based on the “Human Body Model” (HBM) method of ESD testing.

Antennas come in all shapes and sizes and can be used for both radiating and receiving. Selecting a good receiving antenna for emissions testing is not difficult if you take some necessary items into account.

Techniques for accurate power rail testing have to be refined constantly. A new, widely unknown approach combines waveform histograms and free run trigger mode.

This article summarizes the changes in IEC 60601-1-2:2014 Amendment 1:2020 and describes how to conduct proximity magnetic fields immunity testing as required by the standard.

Ethernet solutions have been popular in industrial and computing applications for several decades but were not widely adopted in the automotive area. Automotive ethernet enables fast and robust data communication, with high flexibility in bus topologies for multiple electronic control units (ECUs).

This article addresses China’s latest requirements, including technical details, for 2.4 GHz and 5 GHz equipment.
