Description
This softkey lets you open the ALC loop. Direct and separate control
of the linear modulator circuit (LVL DAC) and attenuator (ATN)
is possible (see Figure A-l). The power level must be set using an
external indicator (power meter/sensor). If the power level is set
when the synthesizer is in CW mode and then pulse modulation is
activated, the peak pulse level equals the CW level. The attenuator
value is set via the Set
atten
softkey
in the POWER menu.
An asterisk next to the key label indicates that this feature is active.
