ITM-20C Remote Service TV Analyzer

ITM-20C Remote Service TV Analyzer

ITM-20С analyzer is designed for remote control of analog and digital СATV signal parameters. It should be placed in telecommunication nodes for continuous and automatic control of signal parameters

 

Features:

  • Level, C/N ratio measurements for channels with analog modulation
  • Level, MER & BER measurement for channel with digital modulation
  • Input RF and optical signal parameters measurements (optical receiver option)
  • Optical signal power measurements (optical receiver option)
  • Channel plan and single channel mode
  • Operating monitoring systems via ViewRSA software & SNMPv1 protocol
  • Security loop connection capability with the transmission of the reported violation into ViewRSA software and through SNMPv1 protocol
  • Firmware updating & device settings via WEB interface
  • Powered by an external DC source or via Ethernet network (PoE option)
  • DIN-rail mounting
