With long control lists, it is helpful to display only a part of the control list. In such
cases, set the "Visible/Bits Visible" to determine the number of symbols/bits to be dis-
played and select "Zoom" to focus the displayed area around the current "Cursor Posi-
tion".
Ramps outside the displayed area are not lost by zooming.

3.5.4.1 How to Create and Assign a Control List
The R&S SMBV100B provides the following ways to create a file containing control sig-
nals:
●
To use the dedicated Control and Marker Lists Editor and create a file in ASCII for-
mat and with extension *.dm_iqc, see "To create a control list in ASCII format
manually" on page 134
●
To use the tag-oriented format and create a control list file, see "To create a control
list using tag file format" on page 173.
●
To use SCPI commands and create a file in binary format, see "To create a control
list in binary format" on page 174.
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.
If a new file has been created, the control list is empty.
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.
b) Tap at a position which requires a ramp. The number or ramps per marker is
unlimited.
