Gary,
The house symbol means indoor use only.

Hi Gary,
For the symbol with the arrow pointing into the house, I would say that the
wall wart is intended to
be used indoors, not outdoors. As to the symbols origin, I have no idea. But,
you might want to
check out ISO7000. There's many, many symbols in my 1989 copy (many I'm sure
that you'd

Long live the listserver!
Fast on the heels of the EMC RTTE updates (see Helge's posting in
December), yet another Xmas present from the the Enterprise

Sam,
It is specified in ANSI C63.4 and CISPR 22 to perform initial emissions
testing to determine worst-case configuration and then to perform final
emissions testing. The differences in setup can include cable arrangement,
EUT/peripheral arrangement and modes of operation.
Reducing the
Not having had a product with this variability, I can't offer much from
experience. However,
I would think that not all tests have to be performed at all frequencies.

Hi Luke:
This won't work. If you want to look at how badly online forums work,
look at the IEE website.
Unfortunately, this requires a membership and a
login.
I really would like to know more about the
success of web-based forums.
Best regards,

Thank you for all the comments on the listserver-
based service versus the web-based service.
The IEEE listserver WILL continue.
I apologize for not being clear on this point.
We started with listserver service. However, the
listserver does not satisfy all of the needs of

Hi Jim:
Thanks for your message.
The EMC Laboratory that I work for (Acme Testing Company in Acme,
Washington) has the quietest open-field Emissions Sites (OATS) within a
1000
mile radius. We planned it that way. The village of Acme has a total
population of under 100 people.

Happy Holidays. Thank you for your responses to my last post concerning AC
Power sources. I got a lot of good information.
Next question:
Client has a product that he is offering with various CPU types and speeds(5
to be exact) and is pursuing CE compliance. That is the only

Is there a formal definition for End User, as found in the proposal for the
new EMC Directive ( 2002/0306(COD) )?
Would a component power supply be considered an apparatus under this
proposal?
thanks much.

Maybe one of the group can set up a list server elsewhere if the IEEE is sure
it wants to stop the service.

I shall be sorry to lose access to the daily interchange among the EMC
professionals who've made this list worth subscribing to. Provision of a
link in e-mails is not even a poor substitute for those of us who wish to
use off-line readers. This is reminiscent, in its own inexorable way, to

I would have to agree with the last few posts.
My business partner and I are adding forums on our new site as more of a
courtesy for those that are interested. When we were deciding on this, we
thought about approaching the IEEE and ask them to have us host their
forums/listserv. Of course this
Without the list server, you will lose a massive following. This includes
myself.
