δF = Frequency offset from carrier
Rs = Symbol-rate (Msymbol/s)
DVB-S2 Phase noise
tolerance5
-25 dBc/Hz at δF = 100 Hz
-50 dBc/Hz at δF = 1 kHz
-73 dBc/Hz at δF = 10 kHz
-93 dBc/Hz at δF = 100 kHz
-103 dBc/Hz at δF = 1 MHz
-114 dBc/Hz at δF > 10 MHz
LNB power and control See Table B.13
Table B.11 shows the Eb/No requirements for DVB-S and Table B.12 for DVB-S2
Es/No requirements to ensure error-free demodulation for all supported FEC rates.
3
Enabling this feature disables output transport stream and renders the receiver unable to decode a service. Operational for DVB-S2 modes
only.
4
These specifications apply in the presence of thermal noise at the threshold Eb/N
0
ratio given in Table B.11
5
These specifications apply in the presence of thermal noise at the threshold Es/No ratio given in Table B.12 and assume a degradation to
the thermal noise performance of 0.3 dB.
