ST 111 Detector

ST111 Professional RF detector

The main change in the ST 111 compared to the previous model ST 110 is built into the main unit of the SHF - antenna detector.

ST111 is designed for detecting and locating of radio transmitting bugging devices, such as:

Radio microphones, Including Burst transmitters, and devices with frequency hopping technology

GPS TRACKER

GSM bugs

Wireless video cameras, stethoscopes

Unauthorized used WLAN and DECT devices

Key features

 Separate indication of analog and pulse signals

Displaying of identified signals of GSM (2G), DECT, WLAN (2.4GHz)

Frequency meter

Oscilloscope

Timing diagram

Special software “ST110 ANALYZER”

Firmware update via internet

24/7 monitoring

Log of events

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

ST 110 operates in two main modes: SEARCH and MONITOR.
Additional modes include: LOG VIEWOSCILLOSCOPE and RECORDER.


SEARCH MODE

This mode is intended for search and detection of RD. 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.


1

32-segmental indicator of average power of radio-frequency emission 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 scale
level («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


MONITOR MODE

This mode is designed 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 MONITOR
mode.The classification of the events by time, duration or value of the 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).


ADDITIONAL POSSIBILITIES 

SPECIAL  "ST110 ANALYZER" SOFTWARE

The software is intended to:

  • time graphic display of data and the results of operation of the ST 110
  • the ST 110 remote full control using PC
  • extended settings assignment for MONITOR mode
  • load and display textual and graphical information of the operation of the ST 110 in MONITOR mode (Event Log)
  • firmware updating via internet
