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.
