PCL SPECTRUM ANALYSER
PROPOWER-5
1 GENERAL
1.1 Description
The PROPOWER-5 is six functions in one instrument, Level Meter, Datalogger,
Scan, Tilt, Spectrum Analyser and Transient Detector which makes it an excellent
tool for the installation and maintenance of Power Line Communications (PLC)
systems working in the 1 to 50 MHz range.
As a Level Meter, the PROPOWER-5 enables the following measurements:
Digital PLC channels:
 Channel power measurement by integration
 Carrier / Noise ratio measurement (C/N)
 Level measurement in a frequency
The Datalogger function allows up to 55 loggers or measurements to be taken
and stored, each with C/N ratios and channel power of up to 140 channels. The
measurements obtained may be checked, transferred to a PC or printed at any time.
In Scan operating mode, the PROPOWER-5 indicates the level of all channels
present on the band in a bar-graph display. The span and reference level are user
definable. A moving marker shows the exact level of each specific channel.
In Tilt operating mode, the screen shows, both graphically and numerically, the
difference in levels between any four previously defined pilot frequency channels, in
order to obtain a qualitative measurement on band equalisation.
As a Spectrum Analyser it provides the analysis of the entire band, with a span
defined by the user from 1 to 50 MHz. Furthermore, it is possible to alter the reference
level, and to detect and maintain the maximum and minimum values for INGRESS
measurements.
The Transient Detector mode, permits to count the number of impulsive
interferences and with a level higher than a threshold defined by the user. The
maximum frequency range is from 1 to 50 MHz.
In designing the PROPOWER-5, special attention was given to building a
multi-purpose, accurate, yet easy-to-use instrument. A simple keyboard gives direct
access to the various operating modes and, once in them, any measurement parameter
can be easily changed using the rotary selector/button.
In addition, it has an RS-232C terminal for connecting to a printer or computer for
producing reports on the measurements obtained.

USER’S MANUAL. PROPOWER-5
Page 2 02/2007
The instrument is powered by means of an internal rechargeable battery.
All these functions have been brought together in one instrument weighing only
half a kilo. The ergonomic, sturdy design makes the PROPOWER-5 a working tool
without parallel.

3 INSTALLATION
3.1 Power supply
The PROPOWER-5 is a portable instrument powered by a built-in 7.2 V NiMh
rechargable battery. Before taking any measurement, the user should make sure that
the battery is fully charged (use the mains adapter supplied with the instrument).
3.1.1 Battery charge
The instrument has a 230 V / 50-60 Hz, mains adapter, for use in EUROPE and
other countries, to power or to charge the instrument. (See accessories to request other
types of adapters).
There are two different situations on battery charge:
1) With the instrument stopped, on having connected the external power adapter,
begins a cycle of fast load which duration will depend on the battery state.
For an empty battery this time will be of 3.5 h. approximately.
The charging battery indicator on the frontal panel will remain lit in amber colour
during this period of time.
When the battery charging is completed the indicator will be lit in green colour, to
state that now a maintenance charging process begins.
2) When the instrument is operating and connects the adapter, this one powers the
equipment and provides a battery maintenance charge while the charging indicator
remains lit in green colour.
ATTENTION
When stopping the instrument is reinitiated a
charge process.
It is for that reason recommendable to discharge
the battery using instrument without external
power adapter to make complete the charge /
discharge process.
ATTENTION
The charge system of PROPOWER-5 incorporates
a security system that does not allow the process
charge from certain temperature limit, begining the
maintenance charge instead charge mode when
the indicator flashes in green/amber until the
temperature downs to the required value.
CAUTION
Before using the power adapter, make sure that the
adapter is suitable for the mains voltage.

3.1.2 Recommendations for using the battery
In case of anticipating a long period of inactivity for the equipment it is
recommended to store it with the battery discharged.
When the equipment starts the operation after a long period of inactivity to follow
next steps:
• Put to charge the instrument with the external adapter.
• If it starts with the indicator flashing, wait until pass to the charging mode (indicator
lighting continuously).
• When starting up the instrument make sure that the AUTO POWER OFF function is
OFF, in this case the indicator will be lit in green colour, and then keep it for
approximately 10 to 14 hours.
Use the equipment in normal way, reason why after one to three whole cycles of
charge/discharge, depending on the time and temperature of inactivity, the battery will
have been reconditioned.
3.2 Installation and start-up.
The PROPOWER-5 has been designed for use as portable equipment.
A fully charged battery can power the equipment for more than three hours. When
the low battery indicator appears on the display ( ), the battery must be recharged.
When a fully discharged battery is installed, it is possible that, due to residual
charges, the PROPOWER-5 may start up. In this case, the instrument will automatically
disconnect before the low battery indicator appears on the display.
3.2.1 Contrast adjustment
When turning on the PROPOWER-5, if the on/off key [16] is held pushed, on the
display will appear the message 'CONTRAST ADJUSTMENT - Turn the rotary
selector', then turning the rotary selector [9] it is possible to adjust the display contrast
to get the best viewing according to working conditions. The new contrast value is held
when the unit is turned off and when battery is removed.

4.2 Operating instructions
The PROPOWER-5 has 6 independent operating modes:
The CHANNEL-FREQUENCY operating mode measures the signal level for
a tuned frequency as well as the channel power and the Carrier/Noise ratio
(C/N) for digital PLC channels. Press this key to change between channel
tuning mode and frequency tuning mode.
The DATALOGGER operating mode enables multiple measurements to be
performed and memorised for subsequent checking, transfer to PC or
printing. It can perform and store up to 55 obtained measurements or loggers
in the memory. Each logger carries out, C/N and channel power
measurements on the channels activated in the channel plan (up to a
maximum of 140 channels).
The SCAN operating mode shows the signal level of all channels present on
the chosen frequency band in a bar-graph display. The span and the
reference level may be selected through the rotary selector. In addition, a
moving marker shows the numeric level of any specific channel. This mode
also permits to define the pilot channels, used for the TILT measurement.
This key permits to accede to 2 operating modes:
The SPECTRUM ANALYSER mode provides a spectrum analysis over the
entire band. The span is user definable between 1 and 50 MHz. In addition, it
is possible to change the reference level, and maximum and minimum
levels may be detected and held for INGRESS measurements.
In the TRANSIENT DETECTOR mode, the PROPOWER-5 operates as a
transitory counter in the return path. The level detection threshold and the
frequency margin are user definable.
The TILT operating mode shows on the display, both graphically and
numerically, the level difference between any four channels, previously
defined as pilot channels, in order to obtain information about band
equalisation.

The first page of the global configuration menu permits to modify the following
parameters:
a) CHANNEL PLAN
It allows you to choose the active channel plan between the 10 channel plans that
unit can store (IBER, etc.).
b) EDIT CHANNEL PLAN.
When selecting this field and pressing the rotary selector, the unit accedes to the
active CHANNEL PLAN.
The attached figure shows an example of
channel plan. The first line shows the name of the
channel plan (IBER in the figure), the units of
measurement (dBm). Next line shows the head of the
columns that constitute the channel plan: the first
column (CHAN) shows the name of each channel
(UL12, DL13,…) and the second one (FREQ) the
associated frequency, in MHz. The third column
(BW) defines channel bandwidth, in MHz. The fourth column (ON) activates or
deactivates the channel.
The maximum number of channels in a channel plan is of 140.
The activation (ON) / deactivation (OFF) of the channels affects to the following
operation modes: CH-FR, SCAN and DATALOGGER. When a channel has been
deactivated, this one will not be able to be tuned nor to be measured. This property
allows to make agile the operation of the PROPOWER-5, because it allows to activate
only those channels in which we are interested.
The Edit Channel Plan function allows to automatically activate all the channels
defined in the channel plan by means of the ALL field on the third line. When to the
right of ALL we select ON, all the channels of the plan will be activated, otherwise, if we
select OFF all channels will be deactivated. In order to activate / deactivate a particular
channel, turn the rotary selector [9] until this one appears shaded and then press it, the
cursor will jump to the ON column, then turning the selector it will be possible to activate
it (it appears a cross) or to deactivate it (it does not appear a cross).
Below it appears ∆FCH set to 0,00 MHz. In a range from -2,00 MHz to +2,00
MHz. i.e. the displacement of the channel tuning frequency for those channels that
present a central frequency displaced respect to the one of the corresponding standard
system.
Also this parameter (∆FCH) can be edit in the channel configuration by means of
CONFIG CH-FR option.
In order to quit the Channel Edit press the key associated to the operation mode
which you wish to accede.
To modify the rest of characteristics of the channel plans it is necessary to have

To modify the tuned channel, press the rotary
selector [9] again, the channel field will be activited and
then turning the rotary selector you will be able to
change it.
The attached figure shows an horizontal line at
-15 dBm. This line allows to establish judgements of
channel level acceptance easily. To activate and
define this reference line see the Scan
configuration menu (section 4.2.2.1).
In the case of having activated the broadband
power detection function (POWER MEAS -> ∑PWR)
in the configuration menu of SCAN mode (See
section 4.2.2.1), on the display of PROPOWER-5 will
appear the total power level on the instrument input.
This parameter indicates the total power that is
being transmitted by the connected cable to the
equipment in the band from 1 to 50 MHz.
The SCAN operating mode also allows channels to be programmed for use as
pilots in TILT operating mode, in the forward band (see section 4.2.5 TILT operating
mode).
IMPORTANT
In order to achieve the maximum accuracy, the digital PLC channels power must
be measured always from the CHANNEL-FREQUENCY operating mode.
