Radiated Susceptibility

The Japanese National Institute of Technology and Evaluation has announced that they have confirmed that some of the household electrical heaters available in Japan malfunction when subjected to electrical disturbances.

CISPR Publications 24 and 35 allow radiated and conducted immunity tests to be performed using I% or 4% steps. This article looks at measured radiated immunity test data to determine the typical shapes of radiated susceptibilities for multimedia equipment. The authors consider what those shapes tell us about the validity of the 4% step method.

The shielding performance of bayonet vs. threaded connectors is measured and some possibly surprising conclusions are drawn. Bayonet connectors – more useful than you might think.

In this article, we detail the key changes between MIL-STD-464C and MIL-STD-464D, the recently-released update to the standard.

This is the fourth and final article in our series commemorating 70 years since the advent of modern EMC testing.
