Testing to UNECE Regulation 100 Requirements for Electric Vehicle Batteries

This article discusses Revision 3 of UNECE Regulation No. 100, which introduces new safety requirements for rechargeable energy storage systems in electric vehicles, including updated tests and standards for battery packs and thermal propagation protection.

Evaluation of Automotive Electronics Product Development Process and Implementation of In-House EMC Development Testing Facility

This article discusses improving automotive electronics development processes, emphasizing early testing and in-house EMC capabilities. It highlights current limitations, suggests efficiency enhancements, and provides practical advice for implementing cost-effective EMC testing setups, drawing on the author's extensive industry experience.

Advanced CDM Simulation Methodology for High-Speed Interface Design

A Charged Device Model (CDM) simulation method has been demonstrated to predict CDM fail current of receiving circuits with gate oxide connected to pad. This method involves inclusion of 20ps rise time edge into the stimulus. It was shown previously that this fast rise time component of the pulse can cause the gate oxide damage. The simulation method is intended as a schematic-level tool during pre-silicon design phase to deliver CDM ESD protection. Simulation results are verified by silicon results with qualification CDM test on package and Transmission-Line-Pulse (TLP) measurements on wafer-level.

Understanding the New Capabilities and Regulatory Compliance Testing Requirements for Wi‑Fi 6E & 7

Each new version of Wi-Fi standards offers more capabilities but also more complicated regulatory testing requirements. Deciding which capabilities to include and planning for pre-compliance testing can save multiple trips to the test labs and reduce time to market.

Vulnerabilities of LTE and LTE‑Advanced Communications

LTE and LTE-Advanced technologies are vulnerable to interference as well as jamming. However, strategies and techniques exist to address interference and guarantee coexistence with other services, especially in critical situations. Robust device design and thorough testing are essential for maintaining stable and efficient communication in high-interference environments.

Do Measurements Validate Simulations?

It is common for people doing simulations to make a measurement of a similar set up to validate the simulation. The real issue is whether the tool user understands the problem well enough to capture the important features, and whether the user understands the tool well enough to use it correctly.

The Importance of ANSI C63.27 in Wireless Coexistence Testing for Connected Medical Devices

Integrating a radio into a medical device can have many benefits but also introduces new challenges in compliance. Ensuring coexistence with other radios can be critical to the essential performance of medical equipment.

Increasing Correlation of Testing of Battery and Fuel Cell Powered Systems with Their Real-World Applications

Using established circuit analysis techniques and new capabilities in modeling/simulation tools can improve the understanding of battery and fuel cell powered system performance.

Complying With the EU’s EMC Directive Without 3rd Party Testing

Many manufacturers believe that third-party testing is required to meet the requirements of the EU’s EMC Directive. But there are other, legally acceptable paths to demonstrate compliance with the EMC Directive that do not require the use of a third party.
