video bandwith for DVB-S2X/S2

Jun 25, 2024

DVB-S2

the method for calculating the maximum input bitrate of DVB S2 Modulator is as following:

DVB-S2 Max. Input Bitrate = SymbolRate * (spectral efficency). Spectral efficency can be gotten

by looking up the table from standard document as attached file.

e.g. : 8psk, 9/10. from attached PDF,we can get spectral efficency=2.679207, if symbol rate is

21.6Msps, then the max. input bitrate is 21.6*2.679207=57.8708712Mbps.

Please refer table below:

For DVB-S2X, the method is similar, see table below:
