The Noise Cutoffs menu allows you to set the muting thresholds for both audio and
video in the event of a noisy signal. This menu has the following structure:
NOISE CUTOFF
Trnsprt (DVBS Marg)/Trnsprt (DVBS2 Marg)
Description: 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.
Parameters: Cutoff - This 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, and un-muted (e.g., restored) when the C/N margin
rises above 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.
