Basics
You should know that there are three different kinds of cell
towers (in Germany): GSM900, GSM1800 and UMTS.
8.3.
Measurement
As GSM900 has the highest availability, it is measurable almost
everywhere and thus optimally suited for explaining usage of
Spectran:
Now, simply press the 7 key for setting up optimal parameters
for measurement of GSM900 cell towers. The Status display
should now show “GSM900”. Now, you only need to choose
the correct operation mode:
8.4.
Operation mode „Spectrum analysis“
Now press the Enter key until the Display Mode status field
reads „Spectrum“. Should you have “good reception” and a
properly aligned antenna (this is important), you should now
have results similar to those shown in the image on the left.
However, should the large Main display show “---“, or “-150”, no
signal is being received and you need to change your location
or align the antenna differently. During every measurement, a
little dot moves from left to right in the Graphics display. Only
when this dot reaches the right border, the current
measurement is finished an all readings are updated.
(Depending on the settings possibly the dot is too fast for the
human eye)
The Main display always shows the level of the strongest
signal, „-45“ in our example. The higher this figure is (the closer
it gets to “0” or a positive value), the stronger the received
