Options Description
Enable or Disable Sets whether to enable or disable the
noise cutoffs functionality.
-5.0 to 20.0 dB This 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 transport 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 mute is the lower limit for the
transport C/N margin setting. The
transport will be muted when the C/N
margin is below the cutoff setting for a
nominal delay of 1 second. The delay is
between the time the condition is first
detected and the time the transport is
muted.
5.0 to 20.0 dB This sets how the receiver reacts when the
signal quality is severely degraded when

This allows you to set the transport 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.
This is the upper limit for the transport
C/N margin setting. The transport will be
un-muted (e.g., restored) when the C/N
margin rises above the Restore setting for
a nominal delay of 8 seconds. The delay
is between the time the condition is first
detected and the time the transport is
restored.
