What's New

The U.S. National Aeronautics and Space Administration (NASA) reports that the Sun emitted another round of solar flares recently.

The U.S. Federal Communications Commission (FCC) has affirmed a $2.4 million financial penalty against a Florida man for illegal pirate radio broadcasts in North Miami, Florida.

This article summarizes the current state of affairs of standards documents sponsored by the IEEE EMC Society, including areas where there is active development in progress, as well as information on those standards that are currently stable and those that are currently inactive. We’ll also advise readers on how to become more directly involved in the IEEE EMC standards development efforts.

The international standard for electromagnetic emissions from industrial, scientific, and medical equipment has evolved dramatically since 1975. From basic measurements at 100 meters to today's sophisticated testing protocols covering robots and wireless devices, CISPR 11's journey reflects our increasingly complex technological landscape.

The purchase or sale of a company or product line can create big problems in product liability and product safety for both the buyer and the seller. Comprehensive audits should be conducted before an acquisition/sale to identify potential risks in these areas and help to clearly describe the risks assumed by each party in the purchase and sales documents.

This is the second of seven articles devoted to the topic of shielding to prevent electromagnetic wave radiation. This article discusses the normal incidence of a uniform plane wave on a solid conducting shield with no apertures.

Traditional Charged Device Model testing falls short for bare dies in 2.5D/3D devices. With discharge currents reaching 500 mA at just 5V, existing methods can't handle the unique challenges of testing unpackaged components. CCTLP emerges as a promising alternative for reliable low-voltage testing.

This white paper explores the evolution and critical role of advanced hipot testers in ensuring product safety. It details how modern testers perform dielectric withstand, insulation resistance, and ground bond tests, complying with global standards like IEC and UL. The paper emphasizes the necessity of reliable, accurate testing in manufacturing and certification processes.

When working with high-voltage test and measurement equipment, electrical and test engineers strive to achieve precise readings while also maintaining a safe work area. They employ external probes such as high-voltage dividers, but these instruments have drawbacks and are prone to errors. This white paper describes an alternative approach to high voltage calibration.

This resource traces VSWR from telegraph linemen using light bulbs to detect transmission line faults to modern RF measurements. It explains how improper line termination creates reflected signals that combine with forward waves, forming standing wave patterns. The evolution demonstrates how VSWR became a standard parameter for measuring reflected power in RF systems.
