Testing

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.

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.

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.

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.

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

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.

This blog explains CDM ESD testing using the field-induced (FI) method, which is important for semiconductor manufacturers. It covers building a CDM-FI tester, waveform details and verification, and qualification nuances. 

Leakage or touch current tests for electrical shock protection is mandated by safety standards in the process of issuing a safety certification for various electrical products. In this article, electrical shock sensation experiments were conducted for a complex waveform composed of a combination of 60 Hz and a higher frequency sinusoidal signal.

Recalls can create huge problems for manufacturers and product sellers. They can generate new product liability lawsuits that are harder to defend, involve a significant financial cost to implement, and create reputational problems with consumers and retailers. Manufacturers must carefully design a recall or other corrective action that is as effective as possible and adequate under the circumstances. Various government entities are issuing new requirements that can help with these efforts.
