The complex is designed for long-term round-the-clock, periodic or operational monitoring of radio placement, digital signal processing and analysis, detection of unauthorized radio emissions in the inspected premises, detailed study of radio signals, localization of radiation sources, as well as for creating archives of radio monitoring results.

The complex performs radio monitoring in the operating frequency range, stores panoramas of ranges, spectra of individual signals and the main radio technical parameters of detected radio signals in the computer memory.

The complex solves the following tasks:

1. Reception of signals in the entire operating frequency range, measurement and fixation of radio signal parameters in computer memory in automatic mode: level, estimated frequency value, occupied frequency bands, time to go on the air;


2. Panoramic analysis in the entire operating frequency range or in individual sections, identification of changes in the surrounding radio environment;


3. Accumulation and maintenance of a database of panoramas for the entire time of operation and processing of measurement results;


4. RF and LF analysis of received signals with documentation of the analysis result;


5. Technical analysis of radio signals: digital (quadrature) analysis of signals in real time, filtering, decimation of the original signal to the required frequency band, display of the IQ stream in real time;


6. Recording and playback of demodulated transmissions;


7. Localization of detected transmitters within the premises;

t
8. In the mode of deferred analysis, the amplitude-frequency-time analysis of radiation for the entire observation time;


9. Demodulation of analog video transmitters in the entire operating frequency range;

 

10. Recording of radio signals on a PC hard disk in the form of spectra and quadratures (IQ) for subsequent processing;


11. Automatic identification of digital standards GSM (base stations), UMTS (base stations), DECT, BlueTooth, 802.15.4 (ZigBee), APCO, DMR, TETRA, DVB-T2 with demodulation and analysis of packet headers for networks (allocation of unique identifiers of subscriber devices and base stations) (if the DTest option is available);


12. Analysis of Wi-Fi networks (if RadioInspectorWiFi is available);


13. Demodulation of analog AM and FM and digital transmitters of APCO, DMR, TETRA standards operating in unclosed mode.
