In this first part of a two-part article, we’ll discuss the use of radio modules to enable wireless connectivity of electronic and consumer products, and how to approach radio, EMC and safety regulatory approvals in North America for radio modules and equipment which contain radio modules.
Understanding radio compliance and electromagnetic compatibility (EMC) issues to help ensure that products meet regulatory testing requirements and customer expectations.
Basic Parameters of the Normalized Site Attenuation (NSA) Method for Open Area Test Sites (OATS) and Semi Anechoic Chambers (SAC) in CISPR 16‑1‑4
This article discusses the requirements for the qualification of an Open Area Test Site or Semi Anechoic Chamber for measuring radiated disturbances from 30 MHz to 1 GHz.
The voltage based CDM classification has practically no meaning for IP qualification. In this article, we propose an alternative CDM qualification, which is based on a peak current criterion.
This article presents the results of experiments to measure the effectiveness of lossy material in reducing RF emissions from perforated air vents such as those commonly used on computer enclosures. The results show good performance compared to those with conventional metal vents.
Standardization for EV testing continues to evolve. Tim Horacek, Product Manager of AMETEK CTS discusses trends, challenges and development of testing standards for electric vehicles.
The growth of connected products and the Internet of Things (IoT) presents many challenges and risks to manufacturers and developers.
There are many benefits to semi or fully automated electromagnetic compatibility (EMC) emissions and immunity tests. Product developers and test facilities alike are always looking for ways to improve their dat... Read More...
The usual experience when working with a NRTL is that projects are, more often than not, late, costs are overrun, and certification reports often inaccurate. This is not always the fault of the NRTL.
This article describes a proposed addition to the IEC 61000-4-3 standard. This addition would allow detailed testing of a product while coordinating and documenting the frequency changes of the test.
