Purpose: The ST 107 RF Detector (BUG Detector) is designed to detect and locate the sources of electromagnetic radiation from surveillance devices (eavesdropping devices), such as: radio microphones (Bugs); telephone transmitters; radio-stethoscopes; hidden wireless video cameras; radio beacons; tracking devices; unauthorized use of GSM and DECT cellular phones; unauthorized use of Bluetooth and 802.11 (WLAN, WiFi) devices. ST 107 Detector of a field differs from ST 007 additional opportunities: The Additional frequency range of 2.5-7 GHz (together with the SHF antenna) Threshold level and accuracy of measurement of a frequency meter is raised. Identification BLUETOOTH is improved. Identification of a signal 802.1g and base DECT is added. USB port. Built in Li-Pol accumulator.

The ST 107 utilizes the principles of wideband detection of electric fields. The ST 107 operates in three main modes:
- Search;
- Monitoring;
- Log view.

Search Mode

This mode is intended for detecting sources of electromagnetic radiation.

In this mode, the ST 107 receives radio signals, detects them, and outputs them to the built-in display and as an audio signal to the earphones and the built-in speaker. The level of the signal is indicated on two 32-segment level meters on the display.

Adjacent segments light up to indicate the average value of the level of the detected signal, while a single lit up segment shows its peak value.

The ST 107 can measure current frequency values of the radio signal and determine its most stable value (for signals with a constant carrier frequency).

The ST 107 also displays the detection of GSM, DECT, Bluetooth, and 802.11g (WLAN, WiFi) signals.

	1	The number of displayed Bands /temporary indication of zero level of gauges
	2	indicates the high-pass filter is on
	3	32-segment meter indicating the level of 1 Band
	4	32-segment meter indicating the level of 2 Band
	5	current absolute value of the zero level of Band 1 dB	radio signal frequency
	6	current absolute value of the zero level of Band 2 dB
	7	indicator the level of pulse power
	8	type of detected signals
	9	Indicator the level of integrated power
	10	current range of level gauges

 

Monitoring Mode

The Monitoring mode is intended for detecting sources of electromagnetic radiation and storing data in NVRAM. The maximum number of events that can be stored in NVRAM is 4,096. The events can be viewed when the detector is in the Log View mode.

The Monitoring mode has an extended range of alarm signals, which can be triggered if the signal passes a certain level or frequency threshold, or if a certain type of signal is detected (GSM, DECT, Bluetooth, 802.11). It is possible for the user to schedule the ST 107 to turn on and off.

This mode has two basic operations:

User controlled operation

The ST 107 is placed so that it is visible to the user. This is useful for detecting devices for the unauthorized obtaining of information among the visitors of an office, for example. Autonomous operation

The ST 107 is placed in an area where the use of eavesdropping devices is suspected, and the electromagnetic environment will be monitored during a pre-programmed period without user interference.

	1,3	indicators the level of integrated power in the first and in the second frequency range.
	2,4	threshold level markers of integrated power: when the level exceeds the set threshold level, the event is logged in the protocol (set via the menu)
	5	type of detected signal: DECT, GSM. Bluetooth, and 802.11 and signal frequency in the XXXX.XX MHz format
	6,7	indicators the level of pulse power in the first and in the second frequency range.
	8,9	threshold level markers of pulse power: when the level exceeds the set threshold level, the event is logged in the protocol (set via the menu).
	10	current number of logged events in a monitoring session

Protocol View mode

The Protocol View mode is intended for viewing the log of events stored in the ST 107's NVRAM during Monitoring.
Events can be sorted by:
- time;
- duration;
- signal level;
- frequency value.

	1	memory bank number (1-9).
	2	current event number (001-999)
	3	total number of events in the bank (001-999)
	4	event duration (hours:minutes, max, 99:59)
	5	event beginning time (hours:minutes)
	6	date of the event (day and month)
	7	threshold level markers
	8	signal type (DECT, GSM, Bluetooth, 802.11)
	9	signal levels of the event.

"ST 107 PC DATA" Software intended to:

• display real-time data and the resuts of operation of the ST 107;
• load and display textual and graphical information of the operation of the device in Monitoring Mode (Event Log);
• operate the device remotely from the PC.

For software upgrades (new versions, additional features), connect ST 107 via USB Port to your PC, and visit the manufacturer's site; the instrument will be reprogrammed automatically.
