7.3.3.1.7 Edit-Tx-Carrier Menu
This menu has the following options:
•
Enable.
This controls the carrier (on/off).
•
Power.
This option controls the IF output power level.
•
Frequency.
This sets the IF frequency used to transmit to the satellite.
•
Inversion.
This controls whether the I and Q channel outputs are swapped, to give
Spectrum Inversion.
•
Roll-off
. This controls the slope (gradient) of the carrier at its edges and therefore
controls the occupied bandwidth.

. This submenu provides AUPC (Automatic Up-link Power Control), BUC
Type selection and BUC control menus. AUPC attempts to maintain the remote Eb/No
at a specified target level by varying the local modem transmit power level. Note that
when AUPC is active then the ESC overhead channel is not available for user data.
