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 has 2 identical channels of radio frequency paths and allows you to work in synchronous mode (2 channels are synchronously tuned in frequency and IF reports are recorded from one hardware pulse) and in asynchronous mode (each channel works as an independent single-channel radio monitoring complex, regardless of the other channel).

The complex solves the following tasks:

1. Dual-channel synchronous and asynchronous reception of signals in the entire operating frequency range and fixation in computer memory of the main radio technical parameters of detected radio signals in automatic mode;

2. Panoramic spectral analysis;

3. Evaluation of radio signal parameters;

4. Digital analysis and automatic identification of DECT, TETRA, APCO-P25, DMR, Bluetooth, GSM, UMTS (3G), DVB-T2, ZigBee signals;

5. Analysis of WiFi networks;

6. Vector analysis of signals;

7. Demodulation of analog video transmitters in the frequency band 30-21000 MHz;

8. Analysis of the RF component of wired networks;

9. Localization of radio sources in the room;

10. Monitoring of wired networks;

11. Documenting the monitoring result.
