1 INTRODUCTION
The CABLE RANGER is the latest introduction in our CATV analyzer product
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. It also
allows the qualification of VoIP and IPTV services.
The CABLE RANGER includes an optical measurement input allowing field
technicians not only to perform optical power measurements but also to do all
the RFoG related RF measurements thanks to the built-in optical to RF converter.
The CABLE RANGER incorporates the most advanced functions in accordance
with the updates to the latest version of the DOCSIS 3.0 protocol, including
channel bonding technology, which are the latest technology implemented by
operators in the cable data networks.
The CABLE RANGER has all the functions necessary for an easy installation of
any service offered by cable. In addition, its intuitive menu, its adjusted weight
and strength, makes it ideal for fieldwork. The CABLE RANGER features a 7”
professional grade resistive type touch-screen with excellent brightness and
superior image sharpness that can also be used wearing gloves. The instrument
is powered by an internal rechargeable battery.
In the design of the CABLE RANGER it has dedicated particular attention o n
making a practical and precise instrument, as easy to use. The touch interface
allows direct access to different modes of operation and once there, it is easy to
modify any parameter of the measurement.
All this makes the CABLE RANGER in a magnificent tool for installing and
maintaining HFC (Hybrid Fibber Cable) / CATV, analog and digital systems.
Being also very useful for testing DOCSIS data transmission systems.
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). .
1.1 Description
Page 7
April 2018 2 Chapter 1: INTRODUCTION
Figure 1.
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 tes t 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.

►Description
The TILT function is a test to measure tilt in order to equalize the line. TILT is
the difference in amplitudes between the minimum and maximum frequency
that the system can compensate.
The TILT function displays on-screen, graphically and numerically, the
difference in level between any four frequencies previously defined as pilots.
This function works for upstream and downstream band.
Typically, CATV networks transmit two pilot signals at the beginning and at the
end of the band. These two pilots and two more are the ones that can be tuned
simultaneously on the screen. By this way you can evaluate the losses slope and
therefore readjust equalizers of the amplifiers in order to compensate these
losses and ensure a flat response along the band.

Demodulator provides the most important measurements technicians need to
assess digital QAM channel quality. Constellation diagram is a simple and
graphical way to identify signal impairments which impact MER and ultimately
BER. An ideal QAM channel for example will be represented by a set
(constellation) of very sharp dots. These dots will become small dot clouds to
indicate the presence of noise or other signal degradation sources. In addition
to constellation diagram it also measures MER, preBER and postBER
simultaneously with the spectrum trace.

6 MAINTENANCE
Instruments returned for repair or calibration, either within or out of the
warranty period, should be sent with the following information: Name of the
Company, name of the contact person, address, telephone number, receipt (in
the case of coverage under warranty) and a description of the problem or the
service required.
This paragraph offers key considerations regarding the use of the colour screen,
taken from the specifications of the manufacturer.
In the TFT screen, the user may find pixels that do not light up or pixels that are
permanently lit. This should not be regarded as a defect in the TFT. In
accordance with the manufacturer quality standard, 9 pixels with these
characteristics are considered admissible.
Pixels which are not detected when the distance from the surface of the TFT
screen to the human eye is greater than 35 cm, with a viewing angle of 90°
between the eye and the screen should not be considered manufacturing defects
either.
It is advisable a viewing angle of 15° in the 6.00 o’clock direction in order to
obtain the optimum visualization of the screen.
The equipment consists of a plastic case and a TFT screen. Each element has its
specific cleaning treatment.
►Cleaning the TFT Screen
The TFT screen surface is VERY DELICATE. It has to be cleaned with a soft fabric
cloth (cotton or silk), always making the same move from left to right and from
top to bottom, without putting pressure on the screen.
The TFT screen has to be dry-cleaned or with a product specifically designed for
TFT screens, by slightly dampening the cloth. NEVER use tap or mineral water,
alcohol or conventional cleaning products, because they contain components
that can damage the screen.
Turn off the equipment to locate dirt on the screen. After cleaning, wait a few
seconds before turning on.

6.2 Considerations about the TFT Screen
6.3 Cleaning Recommendations

Chapter 6: MAINTENANCE 67 April 2018
►Cleaning the Plastic Case
The equipment has to be disconnected before cleaning the case.
The case must be cleaned with a solution of neutral soap and water, using a soft
cloth dampened with this solution.
Before use, the equipment has to be completely dry.
Never clean with abrasive soaps, chlorinated solvents or aromatic hydrocarbons.
These products may degrade the case.
