Local
Oscillator The Local Oscillator (L.O.) control specifies the
frequency of the LNB local oscillator. The
standard L.O. frequencies for “C” and “Ku” bands
are 5150MHz and 10750MHz respectfully
although, some other variants are included. If
the desired L.O. frequency is not listed, select
either C: Manual or Ku: Manual and enter the
L.O. frequency in the Manual L.O. field. C: 5150
KU: 11300
KU: 10750
KU: 10600
KU: 10000
KU: 9750
KU: 9600
C: MANUAL
KU: MANUAL
Manual LO Allows manual entry of the LNB Local Oscillator
frequency provided that either C: Manual or Ku:
Manual is selected from the Local Oscillator
pulldown menu.
Downlink Allows the operator to enter the satellite
downlink frequency. The value for the Downlink
frequency is used with the Local Oscillator
frequency to calculate the L-Band frequency. The
Downlink and Local Oscillator frequencies can be
used to determine if spectrum inversion occurs
using the following rules. If the Downlink
frequency is less than the Local Oscillator
frequency, then spectrum inversion does occur.
If the Downlink frequency is greater than the
Local Oscillator frequency, then spectrum
inversion does not occur.
Range dependent upon LO
configuration
L-Band Allows the operator to enter the L-Band
frequency within the range from 950MHz to
2.15GHz. The value entered in this field is used
with the Local Oscillator frequency to calculate
the Downlink frequency using the following rules.
If Downlink < Local Oscillator, then Downlink -
Local Oscillator = │L-Band│. If Downlink > Local
Oscillator, then Downlink - Local Oscillator = L-
Band
950MHz - 2150MHz
Modulation
Type Allows the selection of the mod type. DVBS
DVBS-2
CCM Mode* When the Constant Coding and Modulation (CCM)
option is selected, the same modulation mode
and FEC is used for all physical layer framing.
The advantage of using DVB-S2 in the CCM
mode is the improved protection that is achieved
by utilizing the new inner and outer codes.
Another advantage is the 30 percent increase in
CCM
AUTO-CCM
