The ST 032 Multifunctional Detection Instrument is used to detect and locate various appliances used for furtive acquisition of information (hereinafter called 'Special Technical Means', or 'STM'), to reveal natural and artificial channels of information leakage, and to monitor the level of information security.
With the aid of ST 032, the following monitoring and detection tasks can be solved:
1. Detecting and locating radio-emitting STM.
This category of STM primarily includes the following:
 radio microphones;
 phone re-transmitters;
 radio stethoscopes;
 hidden video cameras that utilise a radio transmission channel;
 components of spread HF irradiation systems that operate in the radio frequency range;
 appliances retransmitting PC screen picture via radio channels;
 radio beacons of appliances used for the tracking of moving objects, e.g. people, vehicles, cargoes, etc.;
 radio stations, mobile phones, and telephones with radio-extensions, when activated without authorisation;
 data processing devices detectable by the side electromagnetic radiation they generate (PC components, facsimile units, photocopying equipment, certain types of telephones, etc.)

2. Detecting and locating STM that emit infrared radiation
These primarily include:
 STM with transmissions in the infrared range of frequencies;
 components of spread HF irradiation systems with emissions in the infrared range of frequencies.
3. Detecting and locating STM that utilise various types of conducting lines to transmit data.
Among such are:
 STM utilising AC power lines for the transmission of intercepted information;
 STM utilising phone lines, fire alarm lines, and security alert lines, for the transmission of intercepted information.
4. Detecting and locating the sources of electromagnetic fields, as well as analysing devices that are potentially capable of converting speech information.
These typically include the following:
 acoustic speakers;
 output transformers of audio amplifiers;
 electric motors in tape recorders and Dictaphones;
5. Revealing vulnerability spots, in terms of potential information leakage due to acoustic vibration, and evaluating protection against such leakage.
6. Revealing vulnerability spots, in terms of potential acoustic leakage of information, and assessing the efficiency of sound insulation in various types of enclosed areas.

HF detector/frequency meter, with the identification of GSM and DECT signals.

The operation principle of this channel is based on a broadband detection of electromagnetic power, received by the device's antenna. Signal magnitudes are displayed on two 32-segment scales.
The difference between the two scales is as follows: the upper scale indicates the amplitude mean of the detected signal, whereas the lower one indicates its peak values. Therefore, in the upper scale, AM- and FM-modulated signals will predominate, whereas the lower scale will be registering pulse-, or pulse-like, signals (e.g. DECT, GSM) If indication takes place in both scales, this means that a mixed type signal (such as TV signal) is being received.
Background subtraction and differential mode are also provided.
In this mode, current values of the incoming frequency are measured, and its persistent value determined (for signals with a constant carrier frequency).
The device will advise you if the detection of a GSM or DECT signal takes place.
When ST 032 is connected to the scanning receiver, the reception frequency of the latter can be set equal to that being received by ST 032.

Conducting Line Analyser

While in this mode, the device ensures the reception and graphic display, of signals in conducting lines of various purposes (power mains, telephone lines, lines of fire alarm and security alert, etc.) whether de-energised or with voltages up to 600 V (DC or AC).
The reception is performed by means of automatic scanning within the 0.05 - 9MHz band. For better visualisation, the band is split into three sub-bands: 0.05-3MHz, 3-6MHz, and 6-9MHz.
Auto scanning can be terminated both automatically and manually.
ST 032 connects to the line under investigation via adapter for the conducting line scanning analyser, with the aid of extensions.
Signals in the wire line can be identified on the basis of sound interpretation.
