From open fields to shielded enclosures, radiated emissions testing demands precision at every step — this technical deep dive compares OATS and ALSE measurement methods, antenna configurations, and FCC and CISPR compliance limits across a broad frequency spectrum.

Learn how to calculate RC snubber values to eliminate parasitic ringing in power electronics circuits. This step-by-step guide covers measuring ringing frequency, estimating stray inductance and capacitance, and selecting Rs and Cs values to damp resonance and reduce EMI.

Verification of electrical safety testing equipment is a procedure that is often overlooked by manufacturers. Running test verification is crucial to ensuring that a safety device will properly detect product failures. While the task of setting up a test verification can seem daunting, it’s a simple matter of having the necessary equipment and procedures in place so that the process is easy to follow.

ESD qualification requirements for systems rely heavily on discharge models such as IEC61000-4-2.

The FCC updated its equipment authorization procedures and rules in a number of significant ways.

How is automated handling equipment treated under an S20.20 compliant ESD program?
