    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 fibre 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 7 The main difference between CABLE RANGER CABLE RANGER is that the 3.1 model has an OFDM demodulator that allows you to demodulate DOCSIS 3.1 channels. These channels are made of thousands of narrow bandwidth subcarriers. Figure 1. The Spectrum Analyzer function provides an analysis of the full band and allows changing the reference level and the span among others.
  • Page 8 The Voltage Input function automatically identifies the type of voltage (continuous or alternating) at the input, the voltage and displays the output current. The Optical Power Meter function measures the optical power and other RFoG (Radiofrequency-over-Glass) measurements. In addition, it includes other tools such as datalogger, screenshot, channel plan editor, etc.
