Measuring Radio Receiver (Protected Design)


ARGAMAK-RS Measuring Radio Receiver (Protected Design) is intended for search, detection, identification, recording, demodulation, spectrum and technical analysis of radio signals within HF, VHF, UHF and SHF ranges, measurement of field strength and signals parameters, being a part of fixed, transportable and manpack systems, as well as for localization of radio emission sources when joint operation of several systems, including operation as a part of automated spectrum monitoring systems (ARMADA, AREAL etc.).

ARGAMAK-RS Measuring Radio Receiver

Typical Configuration:

  • ARGAMAK-RS Measuring Radio Receiver (Protected Design)
  • EFSU External Field Sensor Unit (omni-directional measuring antenna)
  • Navigation and timing equipment GLONASS/GPS for location finding and synchronization of the radio receivers when joint operating.


  • Power supply unit with back-up battery and controller
  • Mounting kit to mount the system on a rod or to a wall
  • Shockproof case for storage and transportation
  • Alarm censors
  • Built-in 2G/3G/4G router
  • SMO-BS Analyzers of Base Stations of Communication Systems: BS 3GPP (GSM, UMTS, LTE), BS CDMA (IS-95, cdma2000, EV-DO), BS Wi-Fi (IEEE 802.11 a/b/g/n), BS DECT, BS TETRA, BS TRUNK (DMR, APCO P25)
  • SMO-CT Analyzers of DVB-T/T2/H standards
  • Software Development Kit.


  • Option of operation as a part of automated spectrum monitoring systems (ARMADA, AREAL etc.)
  • To increase measuring accuracy in complicated electromagnetic environment, additional built-in analogue path with 500 kHz bandwidth can be used
  • Protected design (IP67) providing for outdoor operation in complicated weather conditions.

  • Continuous IQ recording within the band up to 22 MHz
  • On-line radiomonitoring mode (real time operation)
  • Automated (scheduled) radiomonitoring mode with control web-interface (flexible task scheduler)
  • Saving and loading of tasks and their templates
  • Collecting data on frequency range loading
  • Search for radio emission sources based on reference spectrum data (mask) or combination of preset conditions
  • Flexible editing of reference spectrum data (group masks)
  • Creating radio monitoring and technical events (changing in radio monitoring equipment or communication channel status)
  • Saving of the event information to database, option to notify about events by e-mail or SMS
  • Display of frequency assignments with detailed information on radio emission sources from database on the spectrum
  • Monitoring of parameters of radio emission sources based on spectrum mask
  • Demodulation, playback and recording of radio signals
  • Saving of radio monitoring results to database (including spectrogram and time sample, for each measurement its date, time and coordinates are recorded) automatically or on operator's command
  • Option of printing or export to storage of radio monitoring results
  • Analysis of operation results in postprocessing mode
  • Creating reports in MS Word, MS Excel, PDF, HTML, XML, and OpenOffice formats, which presents the results in text, table or graphic forms
  • Editing report templates
  • Multiuser operation mode, including differentiation of user rights by access and data editing features
  • Display of the structure and status of system nodes, frequency assignments, relocation of mobile nodes, and operation results on an electronic map
  • Open control protocol, option of integration with external information systems
  • Localization of radio emission sources indoor and outdoor with amplitude method, as well as TDOA and combined methods.
