Is there a reliable, up-to-date web site that lists the ENs that have
been published in the OJ?

Hello Group,
I'm going to be doing some immunity testing for a system that will have
security video cameras attached to it. As we do not make cameras
ourselves I need to get hold of some PAL units that have passed
EN50130-4 (family product spec for security devices. This norm specifies

Here's a problem for you all to think about and hopefully help solve.
I have a room in the corner of my building where I perform EMI pre-scans.
Occasionally throughout the day I have a major interference show up on my
analyzer. It does not come from the EUT. This is
Hello group,
On our OATS, located in a big hall, a burglar alarm from the 80ties
caused broadband noise 20 -150 Mhz Long lines , bad design etc.
This was continuous interference so easy to locate.

== Ce-test,
One way to find out where it comes from is by using a horn antenna
because it is very directional. If you place the horn antenna on a turn
table and connected it to a receiver. You should be able to find out
which direction does the noise come from by turning the table. If the
noise is

Scot,
We had a problem at our lab that sounds very similar to yours. It turned
out to be dirty power line insulators. We were in the midst of a drought
at the time and the rains were not doing a good job cleaning the
insulators. The dirt built up to the point that there was conduction

Hi Scott,

This is broadband, from 30 MHz to
1 GHz, at levels up to 70 or 80 dBuv. It is not like a flat carrier but
rather more like PWM driven motor noise. It lasts from 15 seconds to 1
minute in duration. Then ambient returns to normal.
I've had a very similar problem, 20-30dB

I recommend, for clarity, you state which CE directives you are referring
to. For example a Technical File is
Greetings,
A very good discussion about the use of BeCu gaskets. Thanks
Just a note from the connector technology. This technology uses BeCu for much
the same reason we do but there is the need for very low impedance between two
mating and seperable connectors. In this case the materials and

I have a couple thoughts for you quick as they maybe given
that I am trying to go home! :-)
1) Is the interference line-locked? Try triggering off the
line freq once...
2) Is the building`s electrical supply underground? What
are the ground water conditions like around your plant
Hi, Paul
40 years of IEEE symposia (1955-1995) are available on CD rom from AMC
Applied Microfilm at (617) 893-7863. I don't know, however, if that
includes symposia held outside the US.
