This softkey lets you set the leveling mode of the swept signal
generator to continuous leveling at the desired leveling point. In
this mode, the RF OUTPUT is controlled by the automatic level
control (ALC) circuit, otherwise referred to as the leveling loop. The
attenuator works in conjunction with the ALC to achieve the full
range of power levels. At factory preset, ALC normal is the default
state. An asterisk next to the key label indicates that this feature is
active.

ALC
This softkey causes the ALC to switch off once the desired power
level is reached. When this leveling mode is activated, or when
power or frequency is changed, the swept signal generator switches
to CW frequency and closes the ALC system until the desired
power level is reached. The swept signal generator reverts to its
original frequency/modulation state and opens the ALC system.
This mode is similar to ALC off mode and is useful for narrow pulse
applications. An asterisk next to the key label indicates that this
feature is active.
