Hello Tin,
This is a difficult point but I think on strictly legal terms of
the UK implementation of the EMC directive my old friend and
colleague Chris Dupres is right, although I would strongly caution
against trying it unless you are very sure your equipment does not
cause interference.
It must
Thankyou to all those who responded to my probing question. My initial
response to the engineer was to try and characterise the board using near
field probes however he is intent on looking directly at the 3v power rail.
Given this, my primary concern is with protecting the analyser. Since his

Hi Ron,
That is exactly correct. There is a definite distinction in the U.S.

Hello-
I am reviewing CE documentation for a product of ours that, until recently,
was manufactured in France. I have been able to find the effective dates
and dates of withdrawal for all standards listed in the support
documentation I have, but I ran across something that has me totally
stumped.
Chris,
I am interested in knowing the basis of your response to items 1 and 2, as it
is contrary to my understanding of the EMC Directive.
Specifically, it was my understanding that unless the manufacturer is following
ALL of the requirements specified in Standard(s), that they must follow the

Not only will the LISN have poor performance above 100 MHz, but the
CISPR voltage probe or a "down and dirty" series capacitance will have
trouble at these frequencies, although they will all work well at lower
frequencies. Many of the other suggestions from members on this subject can
CENELEC prA14 passed amending EN61000-3-2 Class D to include only PC's,

you need not comply with Class D after the doa of the amendment.
Nevertheless, if your product is Class D, the Class D limits are the same
as those

Doug,
Since you have LPS and a fire enclosure is not required, your foam is not
within a fire enclosure and so the requirement does not apply. If test
