The Attenuation Test function allows the user to easily check the response of the
telecommunications installations before antennas and headers are working. It
allows the user to evaluate the response along the complete range of
frequencies by measuring the losses (attenuation) in the distribution of TV
signals, comparing reference levels at headend output and at each house
antenna plugs.
Attenuation test function is available for all signals.
1 In Settings select the terrestrial or satellite band.
2 Press the Tools key .
3 Select the Attenuation Test option.
4 The Attenuation Test function for the signal appears on screen.
5 First, set the parameters before the test, pressing the Advanced key.
Parameters to set are: Frequencies of pilot signals (pilot 0, pilot 1 and pilot
2), maximum attenuation and threshold attenuation (for more details refer
to next section).
6 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).
7 Connect the generator and the meter 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 meter. If necessary, the meter can
feed the generator using the Supply Output option from the Settings menu
.
8 Active the signal generator and in the equipment, press the Set Reference
key .
9 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.
10 In each measurement a message over each pilot signal indicates whether
the measure "Pass" or "Fail" according to the parameters set.
