• Power (editable parameter):
Specify the power at which the signal is being transmitted.
• Mod / FEC (eligible parameter):
Introduce the constellation and LDPC FEC value of the transmitted
signal. (Constellation options are: QPSK, 8PSK, 16 APSK and 32 APSK)
(LDPC FEC options are: 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, 8/9,
9/10).
•
Symbol Rate (editable parameter):
In this field the symbol rate of the transmitted signal can be selected.
The valid range is from 2 to 45 Mbaud/s.
•
Bandwidth (reading parameter):
In this field, the bandwidth of the transmitted signal is displayed
according to the Symbol Rate and Roll Off parameters used.
•
TS Bitrate (reading parameter):
In this field it is displayed the bitrate of the transmitted signal according
to the modulation parameters used.
•
Roll Off (eligible parameter):
In this field the value of the roll off factor can be chosen. The available
options are 0.20, 0.25 and 0.35.
• Pilots (eligible parameter):
In this field, selecting the ON option, carrier pilots are transmitted. If
OFF option is selected, then no carrier pilots are transmitted.
• Spectrum (eligible parameter):
Here the spectrum type is configured. Inverted spectrum is just
another method to help preventing signal theft. The spectrum options
are inverted and normal.
•
10 MHz (eligible parameter):
10 MHz reference oscillator mode ON or OFF. This feature provides a
reference signal to the satellite up-converter (BVC) when ON.
