    FIBER-COAXIAL DOCSIS ANALYZER CABLE RANGER 1 INTRODUCTION Description RANGER is the latest introduction in our CATV analyzer product CABLE range. It is an hybrid analyzer (for both fiber optics and coaxial cable) for the installation, configuration and maintenance of interactive video and data services at high speed over TV networks based on the DOCSIS standard.
  • Page 9 In addition, the instrument provides Ethernet, USB and mini-USB port slots to connect to external devices, to download data and to update firmware. Here are some of the most important functions in the CABLE RANGER. Spectrum Analyzer, Scan, TILT and DOCSIS Analyzer functions are performed through coaxial input and are also available for optical fiber thanks to the optical- electric converter (with the exception of Cable Modem emulation).
