Testing

Many individual components in electrical and electronic systems and devices are integrated into systems that are required to function as a whole. Examples of such systems include large electric vehicles, fixed industrial installations, novel scientific products such as quantum computers, and more. There are two EMC-related aspects to consider: intra-system EMC and inter-system EMC. This article focuses on the intra-system EMC aspect while also considering the inter-system aspect.

Whether your organization is seeking ISO/IEC 17025 accreditation for the first time or renewing a current accreditation, there are a few frequently overlooked or misunderstood sections of the standard to pay attention to.

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

Radio signal frequencies are rising to the millimeter-wave (mmWave) range as applications such as 5G networks and automotive radar systems seek more bandwidth at higher frequencies. Testing is an important part of producing new products at mmWave frequencies and coaxial cable assemblies are vital parts in getting signals from a signal generator to a device under test (DUT) and then to an analyzer.

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.

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.
