FUNCTIONS AND FEATURES
✦
SEARCH MODES
In the “All signals” mode the system analyzes the spectrum in the full frequency range and detects signals of all types. In addition to mobile and wireless signals, bugging surveillance devices are successfully detected on other frequencies, such as VHF / UHF radio microphones, 900/1200 MHz wireless cameras, and all other RF transmitters up to 6 GHz.
In the "Mobile/GPS trackers" mode the system detects mobile devices of all standards, including GPS beacons (trackers) that are installed on vehicles and transmit coordinates via mobile networks. Quickly and reliably detects embedded devices (hidden cameras and microphones) that transmit information via mobile GSM, 3G, 4G / LTE and 5G networks (up to 6 GHz)
In the "Wireless/ISM" mode the Delta S quickly detects Wi-Fi, Bluetooth, ZigBee, DECT, LoRa and other radio frequency devices operating on the ISM bands, such as remote controls, smart home components, wireless sensors, etc
In the "Downlinks/Navigation" mode the system scans the downlink bands of mobile networks and bands of Global Navigation Satellite System. With the active “Detect RF jamming” feature the interferences and anomalies created by RF signal jammers will be detected and displayed on the bargraph. Additionally, a special warning sound will be produced
✦
BANDS
Information about the RF environment is displayed on the bargraphs, each responsible for a separate frequency band
The table of bands can be easily adjusted to the frequency allocation of the country of use
It is possible to edit and add new bands Each band has an individual threshold
For each band the following information is displayed: name, frequency, current dB level, peak dB level, maximum dB level, threshold, number of dangerous signals and frequency of the most dangerous signal
The band's bargraph changes color to red when the threshold is exceeded
The alarm history for each of the bands is stored in the log and displayed on the graph
The user can inspect separate bands
✦
SIGNALS
Signals are automatically recognized in spectral traces, added to the signal list, and then automatically updated
The frequency, band, channel, current, peak, and maximum recorded level are displayed for each signal
The alarm history for each signal is stored in the log and can be displayed on the alarms graph
The user can proceed to the inspection of a single signal
✦
MASKING OF BACKGROUND
The "Mask Background" procedure allows the operator to collect and mask external signals, such as TV signals, radio signals, mobile base stations, etc. and thus, focus on identifying only those transmitters that are located in the target area
The duration of measurement can be selected
Background masking can be performed at several points around the target zone
Offset of spectral mask (sensitivity) is set by a threshold
✦
ANALYSIS OF Wi-Fi AND BLUETOOTH
Level of each active Wi-Fi channel is displayed separately when the bands 2.4 GHz and 5 GHz are inspected. Each channel can be studied individually
Levels of Bluetooth, Bluetooth LE and Bluetooth LE Advertising are displayed separately. Each type can be inspected separately
A list of Wi-Fi access points with their attributes and levels can be displayed in the Devices list and on the spectrum
✦
THRESHOLD AND WARNING ABOUT ALARM
Each band has an individual threshold which can be defined by user
The color of the bargraph changes to red when the threshold level is exceeded
The "Audio alarm" feature warns the operator when the threshold is exceeded. The intensity of the alarm increases as the level rises
✦
SPECTRUM
Traces "Live" and "Peak"
Persistence mode
Dangerous signals are marked on the spectrum (ThreatMarks feature)
Waterfall function
Convenient scrolling and zooming
Compatibility with touch screens
Able to zoom in on any part of the spectrum while continuing to search in the entire range
✦
DETECTING OF RF SIGNAL JAMMERS
The system can scan bands where the RF signal jammers operate - mobile downlinks and bands of Global Navigation Satellite System (GNSS)

Special audio alarm warns about jamming
“Noise level” bargraph displays the level of interference and helps to find the source
