To create a control list in ASCII format manually
Use the intuitive build in Control and Marker Lists Editor dialog:
1. To open the "Control Data Editor":
a) Select "Baseband > Custom Digital Mod > Data Source > Select Control List".
b) Select an existing file or select "New".
If the selected file is an existing one, the dialog shows the used settings.

2. Adjust the control signals as required.
a) In the graphic editor "Select Ramp to Edit", select the color-coded trace of the
required signal.

unlimited.
c) To remove a ramp, place the cursor at the desired ramp position.
Press the [Backspace] key.
d) For faster marker and control signal definition, use the predefined ramp func-
tions ("Preset Type"). Apply them with "Preset".
e) If necessary, readjust the ramps with the help of the "Edit Table" function.
f) Define the "Total List Lenght".
g) To display only a part of the control list, set the "Visible/Bits Visible" to deter-
mine the number of displayed symbols/bits.
Select "Zoom" to focus the displayed area around the current "Cursor Position".
Ramps outside the displayed area are not lost.
