Hi,
Yes I attended that presentation.
In ANSI C63.4 Methods for SA there is a "fudge factor" for taking out
the mutual coupling between antennas for 3M SA measurements. Doesn't
this take care of the problem?

ESD simulator that ACCURATELY reflected the Human Body pulse was Andy

OK Here is the latest information I have received from CENELEC.
Last week's Technical Board (BT) meeting confirmed that the
dow of EN 61000-3-2 and 61000-3-3 is 2001-01-01 for all
products.
BT also decided to launch a 2month vote on the withdrawal of
EN 61000-3-2/A12 (that set the dow for 61000-3
I agree with your comment vis-à-vis field strength etc.. As long as the
reading is accurate, the equipment type is moot.
However the attainment of this desired goal is not straight forward.
I am a conservative type and have concerns with dSAs in two areas.
First, dSAs (at least the one I use )

Greetings All,
My company manufactures ITE equipment tested and verified to EN55022 and
EN50082-1 the generic
light immunity standard. With impending release of CISPR24 some
questions come to mind.
1. Does the new ITE immunity standard apply to equipment in a warehouse
(i.e. NOT put into service?
The latest I have from CENELEC is:
EN 50082-1:199X was ratified. Implementation dates:
doa: 1997-06-01, dop: 1997-12-01, dow: 2001-01-01

Greetings group!
I would like to take a survey of the ESD testing practices prevalent in
manufacturers of electronic equipment. The purpose of this information
is to get a better understanding of the alignment of my company with

The answer to question is the same..
I also came from a major PC vendor and shared some of the experiences of my

The three vendors I gave you (Seagate, Maxtor & Quantum) all put significant

test their drives at a component level. They all strive to meet the
