Digital CATV Signal Analyzer (1702 1720)

Digital CATV Signal Analyzer (1702 1720) Description

Feature

• The Model No. 1702 & 1720 enable speedy and accurate measurement of VHF/UHF TV and CATV signals.
  
• These level meters can measure levels of digital broadcast signals as well as conventional analogue broadcast signals.
  
• These compact & lightweight level meters are ideal for VHF/UHF antenna and CATV installations. The 1702/1720 are an alternative expensive, bulky spectrum analyzers. Since they display actual signal level, there is no need to calculate resolution bandwidth corrections. No. 1702 displays C/N snd No. 1720 displays C/N as well as MER & BER measurement on DVB;COFDM, QAM, QPSK signals. The BER test detects problems that remain hidden when viewed on the analyzer screen. The BER measurement provides the installer with a high level of confidence by quantifying system margin or weather resistance.
