Setting up Input Information
Setting up Muting Threshold Controls
1 From the user interface of the D9858, choose Input > Muting Thresholds. The
Muting Thresholds page is displayed.
2 Check the Enable Threshold Muting check box to mute the transport stream and
audio in the event of an unstable, poor, or loss of signal condition. The default is
selected.
3 The Transport Mute field for both DVB-S C/N Margin (dB) and DVB-S2 C/N
Margin (dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, below
the transport outputs that will be muted. The unit uses these thresholds to
determine when to mute the transport in the event of a noisy, poor, or loss of
signal condition. The adjustable operating range is from -30.0 to 30.0 dB. This
setting must be below the respective Restore value. The default setting is 0.0.
Note: The Enable Threshold Muting check box must be checked for these
settings to be active.
4 The Transport Restore field for both DVB-S C/N Margin (dB) and DVB-S2 C/N
Margin (dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, above
the transport outputs that will be muted. The unit uses these thresholds to
determine when to restore the transport after it has been muted. The adjustable
operating range is from -30.0 to 30.0 dB. This setting must be above the
respective Mute value. The default setting is 0.1.
Note: The Enable Threshold Muting check box must be checked for these
settings to be active.
