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.

Adding a guard trace between PCB traces sounds like a simple crosstalk fix — but grounding it wrong can actually make interference worse, not better. See how capacitive and inductive coupling respond differently to grounding placement, and why one counterintuitive result changes the design approach.

A 140 MHz radiated emissions failure led straight back to a 10 MHz clock — but not the way anyone expected. Near-field probing revealed the real culprit was current, not voltage, doubling the frequency where it mattered most. A practical reminder to measure both when chasing down EMI.

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.

As more automotive manufacturers integrate mobile platforms and applications into their vehicles, they’ll only get smarter. Or will they?

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.

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).
