Edit-Tx-Carrier-Advanced-AUPC-Power-Negative Offset Screen
Units:
dBm
Minimum value:
0
Maximum value:
25
Step size:
0.1
Factory default:
1
Description:
This is the maximum decrease in Tx power level that AUPC is allowed to
make to maintain distant Eb/No.
Edit-Tx-Carrier-Advanced-BUC Control Menu
The following BUC screens are available only on L-band modems.
This menu contains the following options:
•
Power offset
. This allows the user to set the system gain or loss after the modem,
so the modem can display the transmit carrier level in terms of either the transmit
power or EIRP, measured in dBm or dBW.
•
BUC type
. Allows the type of BUC to be selected from a list of supported BUCs,
with the option of either open loop control (Independent mode) or closed loop
control (Terminal mode). In closed loop mode, the modem attempts to maintain a
constant BUC output power by adjusting the modem output power and BUC
attenuation level.
•
PSU
. If the modem is fitted with an internal DC power supply option then this screen
allows the user to turn on or off the DC power supply to the BUC.
•
Reference.
This controls whether the modem provides a 10MHz reference signal to
the BUC.
•
Output.
Turns the BUC RF output on or off.
•
Attenuation.
This allows the user to vary the BUC attenuator level.
