Members,
IEC 1000-4-11 is for equipment 16 amps per phase or less. We are looking to
purchase an AC power source that will perform this test as well as the IEC
1000-4-13, 4-14, and 4-28. I don't have copies of these standards.
Do these other standard have a current limit of 16 amps like the 4-1

They have some surface mount chip ferrite beads that are 3A and typically
1300 Ohms at 60MHz and are 1.3 mm high (IM-HH-1M4532-132). They also make
6A parts.

Hi,
Every EMC engineer has to deal with OATS for Radiated Emission test. The
most important parameter of an OATS is NSA (Normalized Site Attenuation) to
characterize how far the site is different from an ideal site. There is an
interesting discussion about NSA data listed in C63.4 in IEEE EMC
6 years ago in a product that was failing our radiated emissions limits I
tried a ferrite sheet that was placed under the cpu clock oscillator with
holes for the leads to run through. The material was about 2mm thick.
Unfortunately I am unable to find the manufacturers part number at this
time. W
