Cutoff/Restore
Sets how the receiver reacts when
the signal quality is severely
degraded when using DVB-S or
DVB-S2 modulation. This allows you
to set the C/N margin values for the
receiver. The receiver uses these
noise values/settings as limits
during normal operation to
determine whether to mute the
transport in the event of a noisy
signal, poor signal or no signal
condition.

the transport Cutoff and Restore
C/N margin values (limits).
Cutoff - This is the upper limit for
the C/N margin setting. The
transport will be muted when the
C/N margin is above the Cutoff
setting, and un-muted (e.g., restored)
when the C/N margin falls below
the Restore setting for a preset
period of time. The adjustable
operating range is from -2.0 to +20.0
dB. The default setting for Transport
Cutoff is 0.0 dB.
