Testing

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.

This article provides an overview of current standards applicable to rechargeable lithium and lithium-ion batteries.

Part II of this two-article series focuses on log-periodic and biconical antenna impedance, VSWR, and radiated emissions measurements.

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.

This two-article series is devoted to a dipole family of antennas used in EMC testing: half-wave dipole, quarter-wave monopole, log-periodic, and biconical antenna.

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.
