TV CABLE / DATA ANALYSER
PROMAX-27
1 GENERAL
1.1 Description
The PROMAX-27 is a portable analyser for the configuration, installation and
maintenance of interactive video services and high-speed data networks over TV
coaxial networks based on DOCSIS 2.0 and EuroDOCSIS standard. On the other
hand, can also analyse services based on IP protocol transmitted by these same
networks, such as Voice IP, IPTV or the Internet.
The PROMAX-27 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 instrument is powered by an internal rechargeable
battery.
In the design of the PROMAX-27 it has dedicated particular attention on making a
practical and precise instrument, as easy to use. A simple alphanumeric keypad that
incorporates soft-keys allowing direct access to different modes of operation and once
there, through the ambidextrous navigation and selection keys it's easy to modify any
parameter of the measure.
All this makes the PROMAX-27 in a magnificent tool for installing and maintaining
HFC (Hybrid Fibber Cable) / CATV, analog and digital systems. Being also very useful
for testing DOCSIS / EuroDOCSIS data transmission systems.
In addition, the instrument provides a serial output for connecting to a printer or
computer and thus obtains reports of the taken measures or access the PROMAX
server for updating.
Here are some of the most important functions the PROMAX-27 integrates.
The Power meter function, across the frequency band, is very useful in
assessing the possible saturation of inputs of CATV amplifiers.
The Meter Level function will take measures both analog channels (C / N ratio,
level of carrier, V / A ratio) and digital (Power, VER, MER, Constellation ...).
The Register function allows you to take and store up to 100 measurements
acquisitions in memory, each one of them can get to store up to 140 channels, with all
the measurements taken in the analysis of data transmission. The acquired measures
can be reviewed, transferred to a PC or printed anytime.

USER’S MANUAL. PROMAX-27
Page 2 07/2008
The Frequency Scan function shows the level of all active channels in the
channel plan through a bar chart.
By the Generator Function, it is possible to create a test signal that allows you to
equalize properly the transmission band (upstream).
As Spectrum Analyser function provides an analysis of the whole band, allowing
change the reference level and the span among others.
As Analyser Data Systems for DOCSIS / EuroDOCSIS, the PROMAX-27 allows
you to measure downstream, upstream and the constellation.
The VoIP function performs a network analysis based on quality service
parameters established by the operation mode UGS (Unsolicited Grant Service) for data
packets transmission,which is based on DOCSIS / EuroDOCSIS standard. Therefore,
those will ensure the best call quality.
PROMAX-27, as IPTV services analyser, performs a comprehensive analysis of
the network based on the quality of service (QoS) named rtPS (real time Polling
Service), which is one of the quality services defined by DOCSIS / EuroDOCSIS
standard. That will ensure the best quality of TV over cable.
The PING function performs an analysis of standard Internet traffic, such as
browsing websites, emails or instant messaging. To check the quality of service, it uses
the quality of service defined as BE (Best Effort) based on the standard DOCSIS /
EuroDOCSIS.
In short, implementation of all these functions into an light instrument of one kilo
and a half weight, ergonomic design and robust, makes PROMAX-27 into an
unparalleled tool at fieldwork.

3 INSTALLATION
3.1 Power Supply
The PROMAX-27 is a portable instrument supplied by a built-in Li-Ion battery.
Before taking any measurement, we must ensure that the battery is charged.
3.1.1 Charging the battery
The instrument is supplied with a mains adapter in order to power or charge the
instrument.
There are two situations that can arise in the battery charging process:
1) Stopped Instrument: When connecting the external power it will start a rapid
charging cycle, whose duration will depend on the battery status. It will take three
hours for a discharged battery. The charging indicator on the front panel [10] will
remain lit in amber colour during this period. At the end of charging and in full
charge, the indicator will be green.
2) Instrument in operation: When connecting the charger, it will start a charging
process in a lower regime and therefore longer. At the end of charging and in full
charge, the indicator will change from amber to green colour.
Figure 1.- PROMAX-27 and mains adapter.
PRECAUTION
Before using the power adapter, make sure that the adapter is
suitable for the mains voltage.

3.1.2 Recommendations using the battery
If anticipating a long period of inactivity of the instrument, it is advisable to store it
with battery fully charged and at temperatures below 25 °C.
It is advisable in these cases doing every 3 months a cycle of charging /
discharging and a subsequent half charge (i.e. 50 %).
3.2 Installation and putting in operation
The PROMAX-27 has been designed for using as portable equipment.
A fully charged battery can power the instrument for over three hours. When
displaying the low battery indicator on the screen ( ), the battery must be recharged.
When starting up with a very low level battery, may be the PROMAX-27 could
start up, because of residual energy remaining at the battery, but the equipment will be
disconnected automatically BEFORE displaying on the screen the low level battery
indicator.
3.2.1 Adjusting contrast
LCD Adjustment contrast is done via the dial (see Figure 2.- [5]) located at the
right side panel of the instrument.
By turning the dial is possible to adjust the screen contrast to get the best display
in any environmental condition. By turning counter-clockwise, the contrast decreases.
By turning clockwise, it increases. The new value of contrast is kept when the
instrument turns off.

4.2 Operation Instructions
The five main functions of PROMAX-27 are accessible from the initial menu,
pressing the key [13]:
1. MODEM MODE: This option allows you to check the response of a data
transmission system DOCSIS / EuroDOCSIS. It works on
both uplink and downlink. It can store and display the
measures obtained from the constellation in QAM modulation.
It also performs tests on applications using IP protocol over
cable (for details see 4.2.3 and 4.2.4).
2. TV MODE: This option has three submenus: Analog TV, Digital TV and
SLM(Signal Level Meter). In these modes we can make the
analysis of analog carrier and digital video carrier, as well as
the demodulation of the audio carrier (for details see 4.2.5).
3. GENERATOR MODE: This option allows you to generate a signal test to check the
upstream traffic (for details see 4.2.6).
4. CONFIG MODE: In this menu you can set basic parameters of the analyser (for
details see 4.2.2).
5. SETUP MODE: This menu allows you to introduce basic data concerning the
system such as time, date and language among others (for
details see 4.2.1).
To access any of these menus, press [13] to access the start menu and
then press the corresponding key ([F1],[F2],[F3],[F4], [F5]) that are found in the lower
frame selection [12].
Pressing the hotkey [13] the instrument will always lead to the start menu,
regardless submenu in which we are.
