Parameter Settings
RF Downlink frequency
In the section General the RF Downlink frequency is shown.
Write it down as it is going to be used for the selection of
LNB LO.
Further down on the page you find the BUC and LNB LO
frequencies.
LNB LO
Depending on the RF Downlink frequency select an
appropriate LNB LO of 9.75, 10.25, 10.75 or 11.25 GHz
which will result in an L-band frequency between 950 and
1650 MHz which is the operating frequency band of the
SkyEdge II Access modem.
BUC LO
Select the BUC to be 12.8 GHz as this is the BUC LO of the
SAILOR 900 VSAT. Remember to inform the hub operator
about this when doing line up and commissioning.
BUC 10MHz
Reference Signal
The BUC 10MHz Reference Signal must be configured to
ON, otherwise the SAILOR 900 VSAT will never allow TX.
Scroll further down to enable GPS for the Location
Coordinates. This enables the serial protocol of the modem
so it can communicate with the ACU.
