Detector production is discontinued and is replaced by ST-111. Press a link below to continue to ST-111description.

Continue to ST-111 specification.

PURPOSE

ST 110 is designed for detecton and localization of radio-wave radiation devices (RD) which are designed or used for unauthorized data transfer via radio channel.

These facilities include the following:

Principle of operation of ST 110 is based on broadband detection of electrical field

ST 110 operates in two main modes: SEARCH and MONITORING.
Additional modes include: LOG VIEW, OSCILLOSCOPE and RECORDER.


SEARCH MODE

This mode is intended for search and detection of RD location. Usage of this mode is based on visual estimation of signal level on 32-segmental scale. Additionally separate indication of continuous and pulse signals,  identification signals of GSM, DECT, BLUETOOTH, WLAN standarts and stable signal frequency are used.

The possibility of acoustic control by means of headphones is provided.

ST 110 RF Detector Search Mode
  1. 32-segmental indicator of average power of radio-frequency radiation source (is pointed on continuous output radio transmitters).
     
  2. 32-segmental indicator of impulse component level of radio signal (is pointed on impulse radio transmitters, such as GSM, DECT etc.).
     
  3. Sensitivity of the indication scales («L» – low, «M» – medium, «H» – high).
     
  4. Frequency bands («B1», «B2») LOW PASS FILTER "LPF" ("F") /short-period indication of set zero scalelevel («ZERO»);
     
  5. Current value of impulse/constant component level, comparing with zero level, dB;
     
  6. Value of periodic signal frequency, MHz
     
  7. Identified data transfer standards (GSM, DECT, DECT BASE, BLUETOOTH or WLAN
     
  8. Change in time of signal level with dominant constant component
     
  9. Change in time of signal level with dominant impulse component
     
  10. Current value zero level of impulse/constant component, dB

MONITORING MODE

This mode is desined for independent operation of ST110 on preset conditions. The information about detected signals is saved by means of non-volatile memory of the device (9 banks, each for 999 events).

Scheduled work operation is also provided.

  1. Indicators of RF transmitter signal level
     
  2. Graphic labels of alarm threshold levels
     
  3. Sign of no permission for recording in EVENT LOG
     
  4. 5-second interval countdown
     
  5. Current value of impulse/constant signal component level, comparing with absolute level, dB
     
  6. Value of the alarm threshold levels of impulse/constant signal, dB

LOG VIEW MODE

This mode is intended for viewing the log of events taking place in the result of the unit running in MONITORING mode.The classification of the events by time, duration or signal level is provided.

  1. Number of viewed bank /Number of banks in action
     
  2. Number of viewed event/Number of events in bank
     
  3. Frequency range, in which the alarm happened (B1: 50-2500 MHz, B2: 2500-7000 MHz)
     
  4. Signal properties in the moment of alarm threshold excess

OSCILLOSCOPE MODE

  1. Type of configuration:
    A - automatic
    M - manual
    and relative value of vertical trace(from 1 to 7)
     
  2. Oscillogram
     
  3. Value of horizontal trace in conversion to full-screen values (1, 2, 4, 8, 16 and 32 ms)
