ESD simulators a.k.a. “ESD Guns” play an important role in product development and their proper selection and use are considered essential to any EMC test laboratory. The focus of this paper is on ESD simulators that perform testing of complete apparatus in accordance with IEC 61000-4-2 and other system level test standards.
This article describes how the principles of laboratory testing of electrical noise impairment can be followed in the automotive sector to dramatically reduce the manufacturer’s development time and effort.
Automobiles present a very harsh environment for the electrical and electronic devices incorporated into them. Two well-established industry standards that define a wide range of electrical disturbance tests are ISO-7637-2 and ISO-16750-2.
The market for automotive vehicles is growing rapidly in China, especially the market for passenger vehicles. This article provides an overview of the general regulations and new rules that will come into effect.
This article discusses the crosstalk reduction between PCB traces by utilizing a guard trace between the traces and investigating the effect of the guard trace grounding.
Clock signals from 1 to 100MHz are usually responsible for radiated EMC problems in HF/VHF range. Harmonics are the culprits, but think in current, not in voltage.
Often (very) fast transients have been proven to trigger latch-up. This kind of latch-up is called transient induced latch-up, commonly known as “transient latch-up” (TLU).
We regularly receive requests from readers to publish stories about real EMI/EMC problems faced by real engineers.
