M&C-FSK
If an FSK-capable BUC is employed, this menu provides

and use it for control and monitor.
DC-Power
If a BUC supply is installed this menu permits the user to
turn DC power ON or OFF.
10MHz
This menu permits the user to turn the 10MHz frequency
reference for the BUC ON or OFF.
Alarm
This menu permits the user to define the upper and lower
limits for a current ‘window’. If the measured BUC current
falls outside this window, an alarm is generated.

This menu permits the user to define the LO frequency used
in the BUC. This is then used in the display of RF frequency
in the CONFIG Tx, Tx Frequency menu.
