ARGAMAK-VM0

ARGAMAK-VM1
Options
- ARC-PS330 Wideband Frequency Down-Converter (2.4 - 30 GHz) to extend the operating frequency range of ARGAMAK-VM0 External Radio Receiving Units
- ARC-ABS External Wi-Fi Analyzer
- ARC-D11 Two-Channel Portable Radio Monitoring System (model 4 or model 5);
- ARC-RP3M Handheld Direction Finder

ARC-ABS
Features:
- Remote control of the System
- Reliable detection of radio emissions of any origin, achieved due:
- Time-referenced receipt of a radio signal by all remote units simultaneously
- High-precision time- and frequency-synchronization of all the units
- Algorithms of multi-channel analysis of signals
- High sensitivity and wide dynamic range, achieved due:
- Operation of ARGAMAK-VM0 and ARGAMAK-VM1 External Units
- Output of signals from remote units in digital form
- High speed of panoramic spectrum analysis, detection of ultrashort signal
- Detection of extraneous emissions within the range of DTV or wideband communication
- High accuracy of localization of radio emission sources, achieved based on:
- Time-synchronization of all remote units of the System based on reference to the unified time scale
- Hybrid localization algorithms, which use evaluation of signal amplitude and time of arriving
- Unified user interface, which provides for control of all the modules, automated processing and visualization of operation results, as well as centralized maintenance of database
- Multi-task and multi-user operation mode
- Scalable architecture, which provides for:
- No limitation for number of remote units
- Significant increasing of System performance due to organizing distributed computations
- Using Ethernet 1G interface for control and transmission of signals (within the distance of up to 100 m) and/or optic cables (at any distances)
- Option of operation as a part of automated spectrum monitoring systems (ARMADA, AREAL etc.)

System provides:
- Revealing of unauthorized radio emissions and localization of their sources inside protected objects and within neighbor area, including:
- Noise-like signals with dynamic frequency-time structure
- Short signal with duration from 1 µs
- Enemy emissions within the range of digital and analogue TV, broadcasting, mobile communication, data link etc.
- Wideband radio signals below natural or "man-made" noise
- 2G/3G/4G/5G subscriber devices
- Recording and technical analysis of radio signals, evaluation of their parameters
- Assessment of hazard degree of revealed radio emission sources
- Analysis of GSM, UMTS, LTE, 5G, CDMA (IS-95, cdma2000, EV-DO), DECT, TETRA, DMR, dPMR, NXDN, APCO P25, Wi-Fi, Bluetooth, Zigbee etc. signal parameters
- Analysis of DVB-T/T2/H, DTMB signals
- Discovery of Wi-Fi, Bluetooth and Zigbee network topology inside monitored premises
- Collecting the information about radio signal parameters in database
- Detection of emissions, which come from monitored objects outdoors (when operated as a part of AREAL-5 System).
- Finding directions to radio-frequency emission sources (when ARC-D11 System with DF antenna systems is available)
- Continuous recording of IQ sampling within the band up to 24 MHz
- Report generation.
