3.3. AUTOMATED MODE
The AUTOMATED mode is used to register signals whose amplitudes exceed the adaptive
detection threshold. It is activated from the DIFFERENTIAL or "PANORAMA" mode by pressing "F2".
Search for signals is performed within set frequency limits, based on the data obtained in the
DIFFERENTIAL mode (if the AUTOMATED mode has been activated from the DIFFERENTIAL mode).
Each detected signal is assigned one of the three categories, "NON-THREAT", "THREAT", or
"UNKNOWN".
By default, those are:
"NON-THREAT" – signals of base stations of mobile telecommunication networks
"THREAT" – signals of mobile digital communication devices
"UNKNOWN" – all the remaining signals.
With the help of ST 500
, bands can be assigned "THREAT" or "NON-
THREAT" status, so that the received signals will be accordingly marked with color, depending on
the frequency band they are in. Upon mode activation, the screen will look as shown in fig.14.
Fig.14
In fig.14:
1 - active channel
2 - number of the detected signals
3 - data sorting type (by level or frequency)
4 - signal level at the current cursor position
5 - current table row
6 - frequency values of the detected signals
7 - levels of the detected signals
In fig.14 frequency values of the detected signals are marked with different colors:
"THREAT" signals - red
"NON-THREAT" signals - green
"UNKNOWN" signals - white
