CDM-600L Satellite Modem
BUC FSK Communications
Turning both BUC FSK and output power leveling ON inhibits capability to
manually change the modem transmit output carrier level since the leveling loop
has control of the modem output. When leveling is turned ON, (ADJ) appears in
the front panel display after the transmit power level in the CONFIGURATION-
TX-POWER menu. Each time this menu is entered, the displayed transmit output
power level is updated with the current value set by the leveling loop.
BUC FSK related parameters, including leveling ON/OFF state and target tracking
level, are stored in nonvolatile memory like all other modem parameters that
determine the set up state. If FSK is turned ON, the modem M&C will set up FSK
in the ON state if modem power is cycled OFF/ON. Likewise, if leveling is ON
and operating, the modem will reestablish the leveling operation using the same
target tracking level after a power cycle or after cycling the FSK state OFF and
then back ON.
