The selected number of symbols/bits around the current cursor position are dis-

6. Use the "Save"/"Save As..." function to save the edited control/marker list under its
current name or under a new name.
Enter the file name in the "Create File" dialog and select the directory (see
Chap-
ter 4.7.1, "File Select Dialog" , on page 116).
Handling of Ramps
1. Set a new ramp
Use the arrow keys or use the parameter "Cursor Position" to move the cursor to
the position where the ramp is to be inserted. Press the ENTER key.
The ramp transition of the newly set ramp depends on the current status (high or
low) of the control signal. If the signal is low, a ramp with low-high transition is gen-
erated; if the signal is high, a ramp with high-low transition is generated.
When ramps are set between existing ramps, the transition of the new ramp is also
defined by the status of the signal before the new ramp. For this reason, a ramp
that has already been set can be assigned low-low or high-high transition (as in the
example), i.e. it will have no effect on the control signal in this configuration. How-
ever, the ramp remains saved, and its position is indicated by a dashed line.
If another change produces effective transition, this ramp will be regenerated.
2. Shift a ramp
An existing ramp can be shifted to any positions. The transitions are adjusted
accordingly.
Use the arrow keys to move the cursor to the ramp position; the cursor changes
colour.
Press the ENTER key. The cursor again changes colour. The ramp will now be
shifted by means of the cursor. Press the ENTER key. The ramp will be set at the
current position.
The ramp transition depends on the status (high or low) of the control/marker sig-
nal before the ramp.
3. Delete a ramp
