Operation
Attenuation test function is available for all signals.
In
Settings
select the terrestrial or satellite band.
Press the
Tools
key
.
Select the
Attenuation Test
option.
The
Attenuation Test
function for the signal appears on screen.
First, set the parameters before the test, pressing the
Advanced
key: Frequencies of pilot signals (pilot 0, pilot 1 and pilot 2),
maximum attenuation and threshold attenuation (see more details in
the next section).
Then it is necessary to
Set References
. This requires a signal
generator. We recommend to use of one of the PROMAX signal
generators:
RP-050
,
RP-080
,
RP-110
or
RP-250
(depending on the
frequency band).
Connect the generator and the equipment where the origin of the
signal distribution is in the installation (antenna, headend, etc.) or
connect the generator directly to the RF input of the equipment. If
necessary, the equipment can feed the generator using the "Supply
Output” option from the
Settings
menu
.
Active the signal generator and in the equipment, press the
Set
Reference
key
.
Once are set the references for the pilot signals, let the signal
generator connected to the source point of the distribution system and
take measurements in each user access point with the equipment.
In each measurement a message over each pilot signal indicates
whether the measure "Pass" or "Fail" according to the parameters set.
The measurement data from the
Attenuation Test
can be saved
through the
Datalogger
tool. To do this, when creating a new
datalogger, in the option "Include Attenuation Tests", select Terrestrial
and/or Satellite. Then, the user must perform a datalogger from the
test point where he is performing the attenuation test. The data will be
saved and can be checked and transferred to a PC. For more
information, see "Datalogger" section under the "Tools" chapter. Also
measurement data or screen image can be exported by pressing the
Export
key (see more details in section "Export key") and after
that display the images or download the data files (in XML format).
