Hello folks -
Can anyone tell me if an ITE device that does not connect to AC Mains must
be NOM certified in order to market the device in Mexico?
One internet link says all ITE, another says AC Mains connected equipment -
I'm confused. Does anyone have a link to or a list of regulated
Okay, here's what I'd like to have ...
Translucent material which is color responsive to emi.
Similar to the material on the side of batteries which
responds to voltage levels.
A pane of translucent material which can be put on the
end of a stick much like a pane of glass or a pane of

A few days ago, I got a little involved in a Usenet discussion about a
contractor using his cell phone within a Telco CO while working on equipment
repairs / upgrades. My position was that I didn't think this was a good
idea, since I know that a cell phone will create about 5 to 10 V/M at about

I mini-evaluated an EMSCAN about 4 years ago. Cute tool!
At the time, this little gem utilized a planar array of 1,024 microantennae,
coupled to an RF processor and pc.
The radiation display is a user-variable-interpolation color map (spectral
or spatial), but a bit imprecise in X-Y location, and
An ETSI representative told me that he thought that most all EU labs have
upgraded their chambers and equipment and are now ready to test. That same
person asked if the US labs were also ready?
Let's hear from both sides of the Atlantic. Are you prepared?

I have two questions and would appreciate any direction:
1) Does anyone know who the Taiwan authority is for GSM phones?
2) Does anyone know of a laboratory that tests GSM phones to their
functional requirements (not EMC and not RF requirements)?
Thanks,

The only way you can get directionality is by looking at which dipoles/loops
get the strongest signals. The dipoles or loops themselves have
essentially no directivity. And the phase relationship won't work like a
phased array radar, because those dipoles and delay lines are tuned for that
Regarding the change in the standard, has anyone started to look into an
upgrade to their compact chambers for stre-e-e-etching the frequency to 2
GHz? If so, what upgrades did you find most cost effective for

No John, I'm not referring to you. (or anyone else in particular) I dont
know you well enough -yet..lol
I'm just spaking on how we do the job of ensuring that our products meet the
standards.
We take this work very seriously and I agree with you that the CE mark is
not a quality mark, but in our
Hi all,
I know this is all hypothetical, but...
I think what's missing from the suggestions is a way to detect
directivity of the emissions. So far what has been suggested is an
array of detectors each linked to pixels. This would be very efficient
at telling you which detectors have been hit

Looking through this link I was fascinated by some of the early issues
regarding electronic devices power with tubes. Additionally there was an
article that
The final draft of the proposed revision of ETSI EN 301 489-1 is in the
voting stage. This standard sets the emissions and immunity requirements for
most all transmitters. A major change has been made to the radiated immunity
requirements by adding the frequencies between 1400 MHz and 2000 MHz. I

of nostalgia.)
First, I have to second any and all comments about the smell of vacuum tube
sets, of any type! Good stuff.
As an FYI to all of you former vacuum tube types who REALLY dig this stuff,
may I suggest
True, but if the display range and bandwidth was tunable, and shown in 3-D
chroma (similar to thermal imagers) rather than time domain -the emissions
would make sense to the wearer. After all, even modern spectrum analyzers
cannot show full bandwidth without compromising adjustments.

Doug has touched on what I think would be a great tool for the
EMI hunter...but rather than a 'sniffer', a 'goggle' similar
to what Geordi wears that facilitates the direct viewing of EM radiation.
Ideally, the device would allow adjustable band 'viewing' of the radiation
