My first response on EMC-PSTC was a bit misleading! For ITE and other portable
devices with cigarette lighter power adapters, 95/54/EC testing is required.
However, 95/54/EC should not be listed as a directive on the Declaration of
Conformity. It should be listed as a technical standard under
As an EMC/safety third party test agency, I have performed both CE-Mark

I have read, with great interest, the first two responses to this
question and am not in complete agreement with them. I guess that this
shows that there are multiple approaches to any compliance issue and
arguments can be made for any of them. With that said, I'll give my
opinion on the most app
Environmental ambients are also a problem on OATS testing. Getting to
know the environmental ambient profile helps. If you have a receiver
with A-B trace capability, you can do a rough check by scanning with and
without the UUT powered, and subtracting the scans, theoretically

EMC testing of a power supply may give you a warm and fuzzy feeling, but
unfortunately it is no guarantee of EMC compliance when configured with
your portable computer. I recommend the computer/power supply
combination be evaluated to the following EMC standards for usage in
environments ran
Use a low-noise preamplifier or preselector with integral low noise
preamp. Companies such as ASI or chesapeake microwave can help you out.
You may want to start with the EMI receiver manufacturer.

Several years ago we combined panels from two enclosures to build a 24'
x 16' x 10' high shielded enclosure. Working with Ray Proof we
converted this enclosure into a fully compliant 1000-4-3 test chamber.
Field uniformity is good with several frequencies having only 12 of the

1000w mono and can be configured for output impedances of 16, 8, 4, 2 or

extra power is often helpful. Even though the amp is rated onl
Competent Bodies have differing opinions. I believe if you contacted
several, they would not all give the same answer on your ESD question.
Clearly, the trend is to test to IEC 801-2:1991 or EN 61000-4-2, which
call out the same ESD discharge network. Contact discharge is the
preferred method and
