A careful review of empirical research, multiple ESD standards, and return on investment provides a strong case for evaluating the installation of ESD flooring in server rooms and data centers.
Part 1 of this two-part article explores some basic rules for terminating cable shields. Part 2 of the article will appear in our October 2022 issue and will summarize the results of recent testing conducted by the author on the shielding effectiveness of screened cables up to 2.8 GHz
The 2003 Columbia re-entry accident was caused by a piece of liberated external tank foam that struck and damaged the left leading edge during powered ascent. Computational and experimental electromagnetics were ultimately applied to foster the development of a new NASA Ascent Debris Radar (NDR) for the remaining 22 Shuttle missions. In the process, countless static and dynamic radar signature and EMI/EMC calculations and tests were completed to assure this safety-critical radar system was ready for the return to flight (RTF) missions.
The selection of component values for common mode filters need not be a difficult and confusing process. The use of standard filter alignments can be utilized to achieve a relatively simple and straightforward design process, though such alignments may readily be modified to utilize pre-defined component values.
Bias tees are an important tool for many applications including vector network analysis. As accurate understanding and modeling of power electronic components becomes increasingly important for the study of their electromagnetic emissions, so do broadband measurements with bias tees. This paper describes the composition of such a special bias tee in terms of the necessary geometries and circuitry.
Speed and determinism in design, made possible by time-sensitive networking (TSN) technology, is prompting the development of new TSN profiles for a multitude of applications across industry sectors. The IEEE 802.1™ Working Group of the IEEE Standards Association (IEEE SA) offers numerous TSN profiles for applications, including the automotive, manufacturing, and aviation industries.
Secure facility designs often comingle ICS/ICD-705 and NSA 94-106 performance requirements creating project confusion with significant design and cost implications. This article focuses on bringing some clarity to the differences between ICS/ICD-705 design guidance and NSA 94-106 performance requirements. The related secure facility design and construction process is also reviewed.
Hipot (“high potential”) electrical safety testers produce high voltage to perform dielectric withstand and insulation resistance tests. This article discusses the safety considerations and capabilities of modern hipot testers that utilize electronic source technology to assess compliance with IEC-61010.
Product regulatory compliance is a formal discipline that addresses every aspect of the product lifecycle, helping to ensure global acceptance of new and innovative technologies that are environmentally sound and safe to use.
Low-frequency magnetic fields, a type of electromagnetic disturbance commonly found in electric vehicles, can pose potential health hazards to humans and affect the operation of critical EV components. Here are some design techniques to help mitigate the problem.
