ITM-20C, ITM-20T2 TV Remote Service Analyzer

ITM-20T2 and ITM-20C TV Remote Service Analyzers

ITM-20 TV Remote Service Analyzers are designed for measurement of TV channel parameters and transmission of measurement results to remote PC via TCP/IP local area network. The Analyzers are used in the cable TV networks for the purposes of continuous automatic monitoring of signal parameters. There are two versions of the device: for CATV (ITM-20C) and for broadcast TV networks (ITM-20T2).

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 RSA program and through SNMPv1
  • Firmware updating & device settings via WEB interface
  • Powered by and external adapter or via Ethernet network (PoE option)
  • DIN Rail Mounting
