Newtec NTC/2280/XF AZIMUTH SERIES SATELLITE DVB-S2 DEMODULATOR
- Stock: 1
- Code: BS18383
- Model: NTC/2280/XF
Being fully compliant to the second standard for Digital
Video Broadcasting over Satellite (DVB-S2, EN 302307), the Newtec satellite
modulator NTC/2280/xF is one of the first modulators to offer the advantages of
DVB-S2:
1° much better spectral efficiency than DVB-S thanks to the
use of new advanced high-level coding techniques: BCH replaces Reed Solomon and
LDPC replaces Viterbi
2° new modulation schemes: 16 APSK & 32 APSK
3° more roll-off factors (20, 25 & 35 %)
Implementing all these new techniques, DVB-S2 results in a
bandwidth saving of up to 30 % in CCM mode (or 2,5 dB gain margin) and up to
65% in VCM mode compared to DVB-S.
The NTC/2280/xF is also capable of working in DVB-S and DVB- DSNG mode.
