Modulation format: BPSK as per ETSI TR 101 198
QPSK as per EN 300 421 (DVB-S)
8PSK and 16QAM as per EN 301 210 (DVB-DSNG) (HOM option)
FEC rate: 1/2, 2/3, 3/4, 5/6 and 7/8 with QPSK
2/3, 5/6 and 8/9 with 8PSK
3/4, and 7/8 with 16QAM
Symbol rate range: 1 to 48 Msymbol/s (Standard)
0.2 to 66 Msymbol/s (Extended symbol rate option)
NOTE…
For certain combinations of modulation format, FEC code rate
and input packet size, the maximum symbol rate may be limited to
lower values than indicated above due to an input bit-rate
limitation of 213 Mbit/s imposed by the ASI input interface.
