Raymond,
A good starting point for european legislation hunting is
http://europa.eu.int/eur-lex/en/search.html
I recommend you set quite definite search criteria otherwise you will be
swamped.

As much as I'd like to take credit (for all good ideas), it was Scott
Lacey's idea t use the bubble pack. Previously I thought it was only
good for making designers panic when they are testing a new power supply
and you sneak up behind them and pop a few bubbles!

Hi All,
Jim has a good idea here. I have an experiment I use in presentations that
shows the amount of an ESD current that couples onto a probe body (Fischer
F-33-1) varies by about a factor of two depending how the lead is dressed
as it passes through the probe, perpendicular through the center
Brent,
Good idea. I have used making tape to form a thick collar around the cable
insulation. This takes time, but provides very repeatable measurements
(positioning).
I did this with a Fischer F-2000 probe, which has a small diameter hole.

Jim,
I too have played with a sliding probe to find peaks and nulls on cables.
Typically this is for diagnostics purposes only. In order to minimize some
of the uncertainty I will typically place one or two ferrite toroidal cores
on the coaxial cable leaving the current probe as a common mode
Wrapping a strip of bubble pack around the cable a few time is also an easy
way to keep it centered in the clamp.

Jim,
I have experience using current probes on cables carrying differential
digital signals at 500 MHz and above.
I find that standing waves are ALWAYS present on the shield of the cable,
even when the signal circuits are matched (at least as well as practical).
Most of the following experience
David,
I would like to add one remark about some past messages on this discussion
group. EN 61000-3-2 contains limits for professional equipment. This
category applies to medical equipment and any other products used in the
workplace or in manufacturing activities.
I would like to clarify

In my opinion, letting the cable insulation touch the probe body is never a
good idea. I always try to shim the cable and probe in order to center the
cable within the probe opening. The trick is to keep the shims outside of
the probe. A good trick is to make a V block out of wood, with a deeper

Hello everyone.
Does IEC 1000-3-2/EN 61000-3-2 apply to ITE? As I understand it, compliance
to EN 55022 and EN 55024 is sufficient for emissions and immunity for ITE,
and they don't call out EN 61000-3-2. Am I right?
Thank you,
