7. CHANNEL#5. PARAMETRIC DETECTOR
PARAMETER DETECTOR is designed to detect working electronic devices, including those that
do not transmit information during a search.
These devices include:
eavesdropping devices using digital channels for transmitting information;
cell phones;
digital TV cameras;
tracking GPS devices.
Search functions are implemented by the ST 100P module
. It is a transceiver
device that records the modulation of the reflected HF signal caused by low-frequency processes
in working electronic devices.
The analysis of the detected signals is carried out on the basis of the acoustic information
heard in the headphones. The directional antenna allows you to locate the source of the reflected
signal. The distance to it is determined by the change in the signal volume level (the closer to the
source, the louder the signal). The detection range of working digital devices is from 30 to 100
cm.
Composition of the ST 100P module:
transmitter forming a high-frequency probing signal;
a receiver that receives and detects the reflected modulated signal;
directional transmitting and receiving antenna.
The module components are located in a radio-transparent plastic case. The detector is
on the top panel of the main unit using a cable with a
connector. The appearance of the ST 100P parametric detector is shown in
