Enabling this feature disables output transport stream and renders the receiver unable to decode a service. Operational for DVB-S2 modes
only.

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.
