WebThe DVB-S2X standard for a wideband transponder supports channel bandwidths from 200 to 500 MHz. The symbol rate is calculated as B/ (1+R), where B is the channel bandwidth, and R is the transmit filter roll-off factor. This table defines the phase noise mask (dBc/Hz) used to generate the phase noise that is applied to the transmitted signal. DVB-S2 is 30% more efficient than DVB-S. It allows a wider range of applications combining DVB-S features (for household tasks), and DVB-DSNG (for professional tasks). DVB-S2 can adapt codification to maximize satellites resources value. It is compatible with last generation. The main disadvantage, there are many millions of devices deployed using DVB-S over the world which has to be upgraded.
