Features

High update rate, 2000-3000 MHz per second
Frequency range 40 kHz – 6000 MHz
Reaction time: 2-3 seconds
Instantly detects digital signals with short bursts
Can detect and locate the transmitter simultaneously
Quickly and reliably detects all kinds of RF listening devices, including analog, digital, constantly existing and intermittent, sending audio or video, with or without encryption
Finds hidden surveillance devices employing the digital standards GSM, 3G, 4G/LTE, Bluetooth, Wi-Fi, DECT, etc.
Detects illegal information transmission in AC, telephone, Ethernet, alarm and other wires as well as in the infrared range with the help of the supplied Multifunction Probe
Can work in instant detection mode, guarding mode, locating mode and car tracker detection
Has a 20-50 times higher sensitivity and detection distance compared to conventional RF detectors and near-field receivers
Can monitor the RF environment 24 hours a day with data logging
Capable of detecting covert bugging devices with an accumulation function and transmitters hidden within the spectrums of other signals
Supports storage of an unlimited quantity of signals. Full information is stored in the log and can be reviewed during the detection, or at a later time. Multiple logs are supported.
Demodulation of audio in FM, AM, USB, LSB, CW (adjustable BW 3…240 kHz)
Alarm relay output can activate external devices when a dangerous signal is detected (turn on a CCTV system, for example)
Comes in a protected case that allows you to place a 13-14” laptop inside (not included in the supplied set)
Powered from the laptop’s USB

Advantages

✦	What it is: a portable system controlled by a laptop computer
	The high capacity of a laptop’s hard drive enables full data logging during the detection (24/7 possible) Wider screen is more convenient for analysis Compatible with touch screen laptops The handheld use of antennas is more convenient for locating transmitters in hard to access places

✦	Handling of the mobile and wireless bands GSM, CDMA, 3G, 4G/LTE, DECT, Wi-Fi, Bluetooth, etc.
	Mobile and wireless signals are detected simultaneously with analog transmissions Mobile/wireless signals are detected with the use of individual thresholds and are displayed separately from other signals Activities within each band are stored as one signal with a certain danger level to avoid excessive records in the Signals table and to locate the sources with a hopping frequency Additional sweepings on the "short-burst" bands are performed to increase the probability of interception of such signals as GSM, 3G, 4G, DECT, Wi-Fi, Bluetooth, etc. External interference from neighboring mobile phones and Wi-Fi routers can be rejected with the help of the thresholds The supplied data files allow the operator to adjust the system to the mobile/wireless bands employed in the country of use

✦	Sensitivity and detection distance
	The built-in spectrum analyzer has 20-50 times higher sensitivity and detection distance compared to conventional RF detectors and near-field receivers Resistant to interference - sensitivity remains high regardless of the proximity to wireless routers, cordless phones, mobile phones, TV towers, radio broadcasting and mobile communications

✦	Support of the "Known signals" table
	The operator can easily distinguish between safe and dangerous signals The TV frequencies employed in the country of use can be quickly imported from the supplied data files The FM, VHF/UHF police and municipal channels can be collected and stored for further us

✦	Advanced signal recognition method
	The signals are automatically recognized in the spectrum traces and inserted or updated in the Signals table Both analogue and digital signals are captured with an assigning of a corresponding Danger level

✦	Unique algorithm of measuring the signal's Danger level
	Uses a combination of the reference trace and individual thresholds for mobile/wireless bands Takes into consideration both the signal's strength and bandwidth Works for both analogue and digital signals including transmissions with a changing frequency Is used during the locating procedure and provides more reliable results compared to the traditional "signal strength" method.

✦	Low demands on the operator's level of knowledge
	The system can be prepared for detection with the help of the "Update Masks" procedure within a few minutes Manual handing of spectrum traces is not necessary Everything is done automatically after the detection starts The operator is warned by an audio alarm when a dangerous signal is detected

✦	Data logging
	All the spectrum traces and alarms are logged during detection The situation at any given time can be reviewed and studied 24 hours a day logging provides detection of periodically working/remotely controlled bugging devices

✦	Tracking of the signal's activity
	The full history of each separate signal, or of all signals simultaneously, is displayed on the Alarms graph The events at any given time can be reviewed by simply clicking on the graph The operator can see the duration of an activity and as such distinguish between any interference and real danger

✦	The Waterfall and Persistence graphs
	Both the present and previous measurements at any given time can be displayed The displayed time interval (density) is selectable in the range of 2 minutes to 6 hours

✦	Car Tracker Detector mode
	The monitoring of mobile bands can detect signals from GPS trackers hidden within a vehicle

Functions of the software

Rich visual representation: Spectrogram/Persistence, Waterfall, Alarms graph
The Known Signals table allows the system to reject TV, FM and other "friendly" signals while maintaining high sensitivity to unknown signals.
The Detector and Locator allow the operator to perform location of a bugging device with both visual and audio notification
The Alarm Threshold decreases the false alarm rate
The Hold Max Danger feature selects and shows the strongest signals for their location as the system is moved during detection
The Update Mask procedure allows the operator to quickly adjust the system to the local RF environment in order to reject safe signals
Sorting and filtering is supported in the Signals table
The Report function allows the operator to export all obtained information about the desired signals
Is easily localizable to any language

Working modes

Stop/View Log
Review of the detection results stored in the log. The Signals table, Spectrogram, Waterfall and Alarms graph give full information about the detected signals and alarm events
Update masks
Quick preparation for detection – the system automatically accumulates the broadcasting and other safe signals existing in the area in order to pass over them during the subsequent detection
RF Sweep
The main detection mode. Provides maximum reaction time and the highest sensitivity. The operator can move the system or its antenna during the detection.
Guard 24/7
Rejection of short transmissions and usage of two antennas reduces false alarms in this mode. Suitable for 24 hour detection without unwanted false alarms
Car Tracker Detector
Detection of vehicle mounted GPS trackers transmitting the coordinates via mobile networks
Probe
Checking of AC, Ethernet, Telephone and Alarm wires and the infrared/low frequency for the presence of unwanted bugging signals
Signal Analyzer
Analysis, demodulation and physical locating of detected signals
