testing

This article is the third in a series commemorating 70 years since the advent of modern EMI testing. But this last article is itself divided into multiple parts, due to the topic’s complexity.

The first in a multi-part series of articles exploring the background of modern electromagnetic interference (EMI) requirements and test methods covers general topics.

The trend of progressively migrating both ESD and EMC immunity from the system/board to the component level is creating unprecedented challenges for the component ESD designer.

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.

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.

One of the world’s most prolific developers of innovative technology products for consumers and...

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.

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.
