The most common characterization of ground rods actually differs from what is observed in the case of lightning. This article discusses what is observed and how that affects ground rod performance.
Firmware is integral to the operation of most devices, and may represent an easier and less expensive pathway for addressing EMC issues. This article presents different approaches to modifying firmware as well as case studies illustrating the potential effectiveness of this approach.
CDM discharges exhibit a fast initial current step when the stray capacitance of the pogo pin is charged. It is demonstrated that the high slew rate can damage sensitive gate oxides. The miscorrelation of CDM and CC-TLP methodologies is addressed by applying pulses with 20 ps rise time.
Cable discharge events occur more frequently than we think, but they often go unrecognized or undiagnosed for root causes, resulting in unnecessary device failures. This article discusses the origins of three types of cable discharge events.
The goal of this paper is to investigate fundamental mathematical and statistical algorithms for the spatiospectral analysis of electromagnetic coupling in large, complex electronic systems. A novel stochastic Green’s function and a statistical representation formula are proposed, which statistically replicates the multipath wave-chaotic dynamics inside cavity environments. The work achieves a physics-based modeling and simulation capability that predicts the probabilistic behavior of high power radio-frequency induced current and voltages in complex electronic systems.
Answering the needs of managing EMI in actual use, this article provides hands-on guidance to specialists at the factories and elsewhere on measuring conducted EMI where it matters – in their environment. Anyone who knows how to use an oscilloscope can perform such measurements.
OEMs are moving toward the digitalization of the design and integration of electrical and electronic systems in aerospace applications. This approach to design development may help aerospace OEMs avoid possible calamities in the future.
Without much effort and expense, it is possible to perform pre-compliance testing in a manner that saves considerable time and money without commercial or financial risks associated with purchasing a full-compliance test facility.
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.
