Hybrid Optical & DOCSIS 3 Analyzer
Hybrid Optical & DOCSIS 3 Analyzer
Doing your measurements right is not enough in today’s challenging and competitive CATV world. Field crews are demanded to understand and fix problems at the first attempt when going out to a service call and there is no question technicians
are therefore put under pressure. Moreover, problems are not always simple to understand or fix and having a proper CATV
analyzer can make a big difference.
PROMAX first CATV analyzer was developed more than two decades ago and since then things have gone a long way.
Modern CATV systems use as much fibre as coaxial cables if not more. Analog has been replaced by digital QAM and
DOCSIS came into play to provide the infrastructure needed to offer internet connectivity. While all this was happening
PROMAX has been honored with valuable customer feedback which we have incorporated in the different CATV analyzer
families we have been offering to the market.
The CABLE RANGER is the latest introduction in our CATV analyzer product range. It is designed to be very easy to use
yet offering all measurements required working with today’s complex hybrid fibre and coaxial networks.

7” Color touch-screen
7” Color touch-screen
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.
Intuitive user friendly graphical menus
One of the main complaints CATV technicians have about
their test & measurement equipment is that it is not technician-friendly. CABLE RANGER operation is easy and it is
based on a graphical menu. A direct access ‘home’ button
helps you return to a main menu page no matter what function you using.

Optical Measurements
OPTICAL MEASUREMENTS
HFC networks use more and more fibre every time.
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.
In this mode optical power measurement is shown together
with the rest of the RF measurements. RFoG (Radiofrequency-over-Glass) is used by CATV operators because it
allows them to benefit from the advantages of fibre optics to
compete with FTTH service providers.

DOCSIS 3.1 RF COMPATIBLE
DOCSIS 3.1
DOCSIS 3.1 systems can use among other things an extended frequency range which goes up to 1500 MHz in the
forward path with a return band up to 200 MHz. The CABLE RANGER RF input covers up to 1700 MHz.
Spectrum analyzer
SPECTRUM ANALYZER
It is one of the essential functions in a field CATV analyzer.
It allows you to have an
overview of the RF content at
the test point or to analyze a
specific channel in detail and
it is very helpful for interference and noise problem
troubleshooting both in the
forward and return bands.
Signal level and C/N are
displayed along with the
spectrum trace. Also the total
input power is displayed, a
measurement of the power
over the complete frequency
band, which is very useful to
detect saturation caused by
fibre links.

SCAN
SCAN
It is probably the fastest way to check if all signals in your network are present. The SCAN function displays
graphically all the analog and digital channels in a selected channel plan along with their signal levels.
Channel power, C/N, frequencies, channel numbers and total RF power are also shown on the screen.
TILT
TILT
TILT measurements are used to identify system
frequency unbalance which must be accurately compensated by field technicians. Up to four pilot frequencies or
analog/digital channels can be configured to be part of
the TILT measurement which is displayed in both
graphical and numerical formats.

MER, BER, constellation
CONSTELLATION
These are probably the most important
measurements technicians can do 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. CABLE RANGER displays
constellation diagram, MER, preBER
and postBER simultaneously with the
spectrum trace.
Built-in Cable Modem
CABLE MODEM
The CABLE RANGER built-in cable
modem can be used to perform
unregistered measurements such as
the visualisation of the ranging
process or the return path attenuation
measurement. It can also be used for
registered measurements such as
PLR, Delay and Jitter, for IPTV and
VoIP system quality evaluation,
sending RTPS and UGS packets. It
monitors all the IP addresses involved
in the communication process as
well.

DOCSIS bonding group
DOCSIS BONDING
As part of the DOCSIS 3.0 standard multiple upstream and downstream channels can be ‘bonded’ to be used
together as one. CABLE RANGER includes a comprehensive channel bonding screen where information about all
of them is combined with other single channel measurements such as the constellation diagram.
Analog and HUM
Analog and HUM
The CABLE RANGER can
measure video carrier signal
level, Video/Audio and C/N
ratio and HUM in analog
mode. This is all shown
alongside the screen together
with the spectrum analyzer
graphic.

Upstream test generator
Upstream Generator
A frequency and amplitude agile return path generator is also available in the CABLE RANGER. It allows generating
a test signal which can be tuned from 5 to 85 MHz and it can be CW or modulated in QAM and QPSK. It can also be
configured to sweep a specific frequency range within that band.
VoIP functionality testing
VoIP
The CABLE RANGER can be
used to analyze network
performance for VoIP applications using UGS QoS (Quality
of Service) parameters in accordance to DOCSIS / EuroDOCSIS 3.0 standards. UGS
stands for Unsolicited Grant
Service. Most important measurements to assessing communication quality include
latency, jitter, lost packets or
MOS and R value.

CABLE RANGER
Datalogger
DATALOGGER
The datalogger function can perform various measurements including signal level and channel power, carrier/noise,
BER and MER for all the channels listed in a given channel table automatically. All this information is saved in the
analyzer and it can be copied to a pendrive or to a PC for further processing at a later stage.

Input voltage
measurement
Taking screenshots is very easy with the CABLE RANGER.
Whatever’s on the screen of the analyzer can be saved to a
graphic file which will become very handy when doing technical
reports.
The measurement of the DC and AC voltages present at
the RF input is displayed together with the total RF power
for convenience.

Web browser and service activation
WEB BROWSER
The built-in web browser can
be used to register a maintenance action directly on the
operator's website, rendering
the use of other devices such
as laptops unnecessary. The
CABLE RANGER can also be
connected to the subscriber’s
cable modem to perform the
service activation procedures.
EXTERNAL CABLE MODEM
The CABLE RANGER can
also be connected to the RF of
the subscriber's cable modem
to verify it is working properly.
CARRYING BAG
A soft carrying bag and a heavy duty transport case are included
as standard accessories.
