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
ITM-20C analyzer is available in 4 modifications: |
