Description
This softkey activates distortion reduction mo de for deep AM
operation. Deep AM automatically switches to the ALC o leveling
mo de when the mo dulation level drives the \detector-logger" (part
of the RF comp onents, see Figure A-1) b elow its detection range.
The mo dulated waveform is DC coupled and ALC leveled above
0
13 dBm. Below
0
13 dBm the waveform is DC controllable but not
ALC leveled, and is sub ject to drift of typically
6
0.25 dB/s. This
value is reduced by a factor of 10 if the
low
ALC bandwidth feature
is selected. An asterisk next to the key lab el indicates that this
feature is active.

Description
This softkey (Option 002 only) accesses the pulse delay softkeys.
These softkeys let you delay the internally generated pulsed output
from either the PULSE SYNC OUT signal or from the external pulse
signal at the PULSE input.
