testing

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.

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.

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).

Solar Electronics founder Al Parker used to say about EMI testing, “There’s more than one way to skin a cat.” Here are a couple more.

This is Part 2 of an article describing the difference between the electrostatic discharge (ESD) qualification requirements for automotive and standard commercial integrated circuits.

Integrated circuits intended for automotive applications have higher electrostatic discharge (ESD) qualification requirements than those intended for commercial and consumer electronics.
