ST 034

The ST 034 Multifunctional Detection device 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. 

The STM with transfer of information by radio channel. Such devices include first of all:

  • Radio microphones.
  • Telephone radio broadcasting devices.
  • Radio stethoscopes.
  • Wireless Video cameras.
  • Mobile telephones and modems of CDMA, GSM, UMTS, DECT standards used without authorization
  • The devices using digital channels of data transmission of WLAN and BLUETOOTH standards.
  • Radio beacons for object movement tracking.

The STM that use AC power, telephone, security and fire alarm lines for information transfer.

The STM characterized by information transmission in infrared range

ADAPTER OF WIRE LINES (AWL)

In the AWL two transformers are united:

  • The step-down transformer of voltage intended for operation in the channel of the analyzer of wire lines with a range of frequencies from 0.05-15MHz
  • Differential low frequency amplifier intended for operation in the channel LOW FREQUENCY AMPLIFIER with a range of frequencies from 0.3-12KHz.

    AWL saves serviceability at presence on input connectors of voltage (AC or DC) no more 250V.

    DETECTION CHANNELS

    ST 034 has seven detection channels:

    1. UHF detector - frequency meter
    2. SHF detector
    3. Wire line analyser
    4. IR detector
    5. Differencial amplifier
    6. Magnetic field detector
    7. Acoustic probe

    UHF DETECTOR /FREQUENCY METER CHANNEL

    The operation principle of this channel is based on a broadband detection of electromagnetic power. 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 average 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.

    In this mode, current values of the incoming frequency are measured (signals with a constant carrier frequency).
    The device will advise you if the detection of a GSM, DECT, WLAN or BLUETOOTH signal takes place.

    SHF DETECTOR CHANNEL

    Principle of operation of this channel is based on broad band detection of electrical field in frequency range 2.5 - 10GHz using ST03.SHF.


    WIRE LINE ANALYZER CHANNEL

    The receiving part of the channel represents the double superheterodyne with a PLL frequency synthesizer

    Reception of signals is carried out by automatic or manual scanning in frequency range from 0.015 to 15 МHz.

    At a scanning stop acoustical control of the signal, with choice АМ or FM demodulator is provided.
    ST 034 connects to the line under investigation via AWL.
