"Kassandra S6" Portable complex for direction finding and analysis of digital radio signals

Portable complex of amplitude direction finding - analyzer of digital communication standards "Kassandra-C6" is designed to search and localize radio signal sources with the ability to find direction. Continuous, periodic or operational monitoring of the radio environment to detect unauthorized radio emissions with complex algorithms for hiding information, analysis of digital communication standards.

Distinctive feature: existing analogs cannot recognize and separate digital devices operating in the same standard. For example, they will not be able to help the operator in detecting a bugging device operating in the DECT standard, if at the same time dozens of devices in the same standard are operating at the facility.
• "Kassandra-C6" is the first portable search complex for amplitude direction finding of both analog and digital devices with the ability to allocate unique digital identifiers (MAC, LAP, RFPI addresses, etc.).
• "Kassandra-C6 GEO" is the first portable complex of amplitude direction finding with the ability to download maps of any area in real time!

1. Extended frequency range - up to 6000 MHz. The version of the complex for the frequency range from 3 GHz to 21 GHz is produced under the name "Kassandra-C21".
2. Maximum scanning speed - over 2000 MHz/s in the analysis band of 10 kHz, dynamic range - over 110 dB without using an attenuator.
3. Automatic classification of emissions and the ability to analyze digital communication standards. When using the DTest option of the software, the complex allows automatic identification of emissions and can be used as an analyzer of digital communication standards (with demodulation of unique transmitter addresses) DECT, TETRA, GSM, UMTS (3G), Bluetooth, DMR, APCO 25, ZigBee. In real time, the complex demodulates voice traffic of APCO 25, DMR (MOTOTRBO) standards, displays video content of PAL/SECAM/NTSC television signals, and enables digital signal analysis (vector diagram, filtering, decimation, and digital shift of signals in vector form (I/Q)). Classification of emissions is possible both by the standard channel grid and arbitrarily at any frequency, in the entire frequency range - from 25 MHz to 6 GHz.
4. Demodulation of AM and FM signals.
5. Extended version with an electronic compass, GPS/GLONASS receiver, and GEO software option for displaying bearings on an electronic map. The necessary maps are downloaded automatically if there is an Internet connection.
6. Complex software:
• a user interface that can be quickly changed and customized over a wide range;
• formation of a package of tasks for scanning within the operating range with any number of sequentially processed tasks, each with its own parameters;
• panorama of current, maximum, minimum and average values ​​of received signals;
• spectrogram (waterfall) – panorama in time in 2D or 3D representation with no recording time limit;
• marker and cursor measurements;
• saving all work results and the possibility of deferred analysis, activation of a saved task and continuation of recording in the panorama database;
• saving a reference panorama and the possibility of comparing current panoramas with the reference one;
• controlled threshold line, adaptive and dynamic threshold;
• list of signals that have exceeded the threshold (list of detected signals with a statistical viewer);
• formation of a frequency assignment database and means for processing them, including a specialized calculator;
• HF spectrum analyzer for analyzing individual signals in real time; • LF analysis - oscilloscope, low-frequency spectrum analyzer, octave spectrum analyzer, recording of phonograms, including five seconds of information before recording, analysis and editing of saved data;
• additional receiver - audio signal source;
• high-frequency signal analyzer in an instantaneous band of up to 4 MHz;
• real-time analyzer in a band of 4 MHz (without limitation of analysis time);
• recording of I/Q data and demodulated audio signals in a band of up to 4 MHz;
• automatic actions upon detection: automatic classification of emissions, recording of audio signal, performing measurements of radiotechnical parameters of emissions;
• additional analysis of the list of detected signals (numeric and graphic), generation of reports on the studied frequency ranges and detected signals, the ability to export them to Microsoft Word®, Microsoft Excel® formats, to text and graphic files;
