The Spectrum Analyzer function provides an analysis of the full band and
allows changing the reference level and the span among others.
The Scan function shows the level of all active channels in the channel plan
through a bar chart.
The TILT function measures the tilt in dB obtained from the difference in level
between four carriers. It is useful for equalizing the line.
The DOCSIS Analyzer measures downstream, upstream and constellation. It
also can emulate the Cable Modem using the internal Cable Modem. The internal
cable modem functions are Ranging, Registering and IP access.
The External Cable Modem function connects the equipment to an external
cable modem. It extracts a sample of the Upstream signal displaying its
spectrums on screen.
The Upstream test function creates a test signal that allows you to analyze and
equalize the transmission band (fix mode or sweep mode).
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.
In short, implementation of all these functions into an light instrument,
ergonomic design and robust, makes the
CABLE RANGER
into a productive
and efficient fieldwork tool for the installer.
