8.1.2. SEARCH IN THE PANORAMA MODE AND IN THE DIFFERENTIAL MODE
PANORAMA mode and DIFFERENTIAL mode are used to search for eavesdropping devices in a
difficult electromagnetic environment in the search area.
1.
In the tested room turn on the
player of the test sound (PTS) and adjust the volume level.
2.
Outside the tested room, connect the required antenna (when searching in the 6 GHz - 12
GHz range, you do not need to connect the antenna) and headphones to the main unit.
Turn on the device.
3.
Turn on the receiver in PANORAMA mode.
4.
When searching in the 20 MHz - 6 GHz range, set the optimal gain without overscaling
(gain adjustment is not possible in the 6 GHz - 12 GHz range). Get a difference panorama.
5.
Observing the difference panorama, enter the room. Fix the appearance of new signals or
an increase in the level of previously detected signals.
6.
When new signals are detected, set the marker to the mark of the strongest signal.
7.
Turn on SIGNAL ANALYSIS AT A FIXED FREQUENCY function.
8.
Analyze this signal:
listen to the signal with headphones at different values of the bandwidth;
analyze the signal on an oscilloscope;
fine-tune the frequency, if necessary.
Signs of "DANGEROUS" signals:
the test sound is heard at the frequency of the detected signal;
the test sound is not audible, the oscillogram of the demodulated signal changes when the
test sound changes;
the level of the detected signal increases when entering the tested room.
8.
Analyze other signals in the same way.
8.1.3. SIGNAL SOURCE LOCALIZATION
Acoustic method or Energy method is used to localize the source of the uncoded signal.
Only the Energy method is used to localize the source of the encoded signal.
When using the Acoustic method, the user turns on the PTS, moves it around the tested room
(listening to the demodulated signal in headphones) and looks for a place where the signal is
heard best.
For a more accurate localization, it is recommended to lightly knock on interior items located
near this place. The knocking will be heard well enough through the headphones.
The SIGNAL ANALYSIS AT A FIXED FREQUENCY function is used to implement the Acoustic
The energy method is to determine the place in the room where the signal level will be
maximum.
The search is performed using the signal level indicator, in the SIGNAL ANALYSIS AT A FIXED
