Mexico question

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

Emitters Within a CO

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 2

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

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

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

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

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. -k
