ARC-NK5I handheld measurement system with measurement antenna and a Smartphone as a control and display unit


  • High-stable external reference generator
  • ARC-KNV4 External Down-Converter for Measuring Equipment with directional antenna system (3-18 GHz)
  • Internal storage built in ARGAMAK-M to save recorded signals
  • Directional antenna set for concealed direction finding
  • Broadband radio monitoring antennae
  • Tripod to mount measuring antennae
  • Shoulder bag to carry the system, when operating in concealed mode
  • Mobile control and display unit (Android OS Smartphone) with SMO-ANDROMEDA Software Package
  • SMO-BS Software Packages for Wireless Data Communication System Analysis: BS 3GPP(GSM, UMTS, LTE), BS CDMA (IS-95, cdma2000, EV-DO), BS TETRA, BS DECT, BS TRUNK (DMR, APCO P25), BS Wi-Fi, BS WiMAX
  • SMO-CT Software Package for Digital TV Signal Analysis

The antennae of ARC-A3A can be used both in active and passive mode. The design of the handle and antenna elements enables detection of RF emitters with vertical and horizontal polarization. The handle is optimized for operation in the field conditions. The weight of the handle with the antenna is 800 gram max., the center of gravity is located below the palm level thus enabling to work longer without getting tired.

System Provides:

  • Measuring of electromagnetic field strength and radio signal parameters (when measuring antennae are available) according to certified measuring procedures
  • Panoramic spectrum and technical analysis in real-time and postprocessing mode
  • Automated radio channel monitoring
  • Recording RF signals, demodulated signals, service parameters to PC hard drive
  • Playback of demodulated broadcasts and service parameters
  • Decoding of service parameters of communication systems and digital TV (GSM, UMTS, LTE, IS-95, cdma2000, EV-DO, TETRA, DECT, DMR, APCO P25, Wi-Fi, WiMAX, DVB-T/T2/H).
