SPECTRAN at the airport

Now then, finaly back my report for the airport-measurements:

WOW! If you EVER want to know whats going on in RF go to a airport!
I fond allmost ALL signals that are avaiable from all kinds of
cellphones (GSM900, GSM1800 GSM1900, UMTS!), all handhold phones
(DECT, CT1+ etc.), radar and all types of WLAN (2,4GHz, WIFI and
5,8GHz! LANs) and lots of hotspots (YES the 5,8GHz units do exist and
dont ask me on which SUPER HIGH levels!). Its a real MESS!

But most important was the radar: I found the strongest radar at about
5GHz (its a signal with quite wide frequencyrange) and coud measure it
as expected. With the ultrafast!!! new BETA22 software of SPECTRAN
(see http://www.elektrosmog.de/SPECTRAN-Betriebssoftware.htm )
i could even measure or better "see" the rotationspeed of the radar
itself! The highest signal i got was about 2000µW/m² but i cant tell
how far the radartower itself was because i coudnt see the tower, what
a pitty. Aniway it worked as expected.

P.S. Its quite a problem to travel with those SPETRAN units: Bacause
of the pistolholder and the extraordinary spacy design i allways had
to wait 10-15 minutes on checkin until the total package was checked
for explosives and other unexpected materials. But after that check
all those guys wanted to have a measurement at there workingplace ;-)
Propably thats a new businessidea ?  

Thank you for your report on Spectran regarding radars!
Looks great! Gotta see it (buy it) to believe it! :-)
Let me ask you another question, if you are in a mood for more chatting...

I have done measurements for concerned people like yours at the airport, but
their constant question "So, how dangerous is it?" made me crazy. Because I
can tell them the percentage according to different standards, but there is
no way to say what are the consequences... Also, electrosensitives DON'T
react proportionally to standards.
Anyway, you might be able to tell us is what makes a spectrum analizer more
usefull for such home / office measurements and possibly estimations of
impact?! Although standards are different for different frequency ranges,
that doesn't make much difference for rough estimations which can be made
also with a broadband meter?! I mean - be it a GSM or a radar, what is much
use from separating the signals from the total MW power density at the site
(except for it really looks interesting and fancy)!?

In fact what do you do with your Spectran? We still don't know much about
you!

Hello Drasco,

now THATS one of the mayore advantages of SPECTRAN: That unit can
calculate even quite complexe formulas as the ICNIRP-limit while you
do the measurement. On the ICNIRP limit you MUST know ALL the
frequencys all the time so only a spectrumanalyser can calculate that
complex formula. That feature is quite unique, only the much more
expensive NARDA meters can do that too. My unit (SPECTRAN HF-6080) has
the following exposurelimits "onboard":
ICNIRP (quite complex formula. Its the most popular offical limit)
SALZBURGER VORSORGEWERT 1 (old version)
SALZBURGER VORSORGEWERT 2 (new version for outdors)
SALZBURGER VORSORGEWERT 3 (new version for bedrooms)
There will be a software too, to make own limits on SPECTRAN, says
Aaronia.
Now if you take a measurement you can even switch between that limits
and get a percentage-reading and graphical bar too without disturbing
the main measurement/recording. The measurement is still running while
you have a look on that limitgraphs (ADVANCE HOLD funktion). Its realy
a cool funktion. Very nice to realy "show" people whats going on
instead of saying: You have value "x" and nobody knows how to deal
with that. Very helpfull.

I personaly use the SPECTRAN as a fast (since BETA22, thank good!) and
easy to use handhold for my work. I do a lot of limitmeasurents at
"industrial" customers. As soon as i see that its getting "critical"
(to high values) i use more advanced units (big colordisplay is
allways better), but thats not very often because SPECTRAN helps a lot
and is very accurate too. Its nice to have it because carying the
bigger units is not very funny if you go up the stairs to the towers ;-(((
