Example: How to assign and activate control signals from a control list
Note: Irrespectively on the way they are created, generated control lists are not auto-
matically used.
We assume, that a control list clist.dm_iqc containing information on marker 2,
burst gate and level attenuation control signals is created and stored in the direc-
tory /var/user/temp/.
The following example shows how to enable the R&S SMW to:
●
Use the control list for a particular marker output, e.g. the "Custom Digital Modula-
tion > Marker 2".
●
Use the Burst Gate and Level Attenuation control signals as defined in a control
list.

How to Create a Data List Using Tag File Format
The R&S SMW provides the following ways to create a data list file:
●
To use the dedicated "Data List Editor" and create a file with extension *.dm_iqd,
see "To create data lists manually" on page 288.
●
To use the tag-oriented format and create a data list file, see "To create a data list
file using tag file format" on page 981.
●
To use SCPI commands and create a file in binary format, see "To create a data
list in binary format" on page 982.
To create a data list file using tag file format
► Use a hex data editor and create the mandatory tags: {TYPE}, {DATA
BITLENGTH} and {DATA LIST}
Consider the tag syntax and rules.
The following is an example of the data list file content. The tags are separated by
line breaks for better reading. The text in brackets is short explanation.
For details, see the tag description:
● TYPE
● {DATA BITLENGTH}
● {DATA LIST-Length}
{TYPE:SMU-DL}{COPYRIGHT:Rohde&Schwarz}
{DATE:201-06-11;15:00:09}
{DATA BITLENGTH: 8}
{DATA LIST-2: #d0d1...d7}
(1 byte containing 8 data bits d0 to d7 in binary format, where d0 is the MSB)
