demodulators. AUTO is only available in DVB-S.
Pilot
DVB-S2 allows the option of inserting bursts of
pilot tones that are very robust and prevents the
carrier recovery system from failing prematurely.
However, when pilots are enabled, the total data
rate throughput is reduced by approximately
3.0%.
note: Pilot is not applicable in DVB-S or
AUTO-CCM modes.
FEC Frame
When operating in DVB-S2, the Frame Type
Type*
options are either Normal or Short. The Normal
64,800-bit FEC frame provides better protection
but introduces more latency compared to the
Short 16,200-bit FEC frame. Therefore, the
Short FEC frame type should be selected in
applications where latency is critical and the
longer frame type should be used to optimize
protection.
note: FEC Frame type is not applicable in DVB-S
or AUTO-CCM modes.
LNB Menu
LNB State
This configuration will enable or disable power on
the input connector to power the LNB. If on, the
user selected voltage and tone will be placed on
the connector via the Polarity and Tone
configurations.
LNB Polarity
This control is primarily used in "Universal" LNB
applications. The LNB Polarity control allows for
LNB polarization selection; the 13VDC source will
select the Vertical polarity and the 18VDC source
will select the horizontal polarity. For typical "C"
and "Ku" band applications, the 18 VDC option is
recommended.
LNB Tone
This control is used only for Universal LNB
applications. A universal LNB can route the high
or low band from either polarity to the IRD. The
high band is selected by enabling the 22 kHz
tone and the low band is selected when the 0 Hz
tone is enabled.
