7.2 Performing Satellite measurements
Selecting SAT from the Home page, or pressing the SAT button on the keyboard will
activate the satellite measurement interface. The first time the user enters this function
is requested to select a satellite plan among the canalizations stored in the meter:
Once the plan selected, position the selector over the
MEAS icon to start the measurements.
The satellite measurement interface is composed by two different screens; in the first one, the
basic signal parameters are displayed; in the second one, constellation diagrams as well as the
Transponder parameters are displayed.
Here is the first measurement screen, with its 6 sections:
1. Satellite tuning parameters: here the user can find the frequency, the modulation and the
polarization parameters for the received satellite signal as well as the chosen satellite plan
and transponder number. Once the signal is locked, the modulation type (DVB-S, DVB-S2
Single/Multi-stream, DSS) and Symbol Rate are automatically detected. If the signal is
Multi-stream and the correct PLS has been applied (see paragraph 5.3 for details), by
default
the first ISI is locked and demodulated.
2. Basic signal measurements: RF level, MER, Noise Margin, bBER and aBER (DVB-S)/PER
(DVB-S2) are displayed. Along with aBER/PER, the meter provides also the parameter
ERR. This parameter stores the overall number of errors detected during demodulation so
that if the meter is left for a long time on the same signal it is possible to detect temporary
signal degradations.
