7.8.2 Operation
Attenuation test function is available for all signals.
In Settings select the terrestrial or satellite band.
Access the MEASURES or SPECTRUM mode.
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.
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).
