Enable the instrument to use the control list, e.g. for the marker and/or other con-
trol signals.
Enabled control signals are indicated as active in the "Configure Control Signal"
section.
How to assign and activate control signals from a control list
Irrespectively on the way they are created, generated control lists are not automatically
used.
To use a marker/control signal from a control list and to output this signal at the suppor-
ted connector, perform the following:
1. Enable the R&S SMW to use the control list for marker output 2.
Output this signal at the T/M2 connector:
a) Select "Baseband > Custom Digital Modulation > Marker > Marker 2 Mode >
CList".
b) Select "Baseband > Custom Digital Modulation > Marker > Local Connector
Setting".
Select "T/M 2 > Direction = Output", "T/M 2 > Signal = Baseband A Marker 2".
2. To enable the R&S SMW to use the "Burst Gate" and "Level Attenuation" control
signals as defined in a control list and output one of them at the T/M3 connector:
a) Select "Baseband > Custom Digital Modulation > Power Ramp Control >
Source > Internal"
b) Select "Baseband > Custom Digital Modulation > Marker > Local Connector
Setting".
Select "T/M 3 > Direction = Output", "T/M 3 > Signal = Lev Att A".
5.6.4.2 How to Create and Assign a Data List
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 287
●
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 326.
●
To use SCPI commands and create a file in binary format, see "To create a data list
in binary format" on page 326.
To create data lists manually
Use the intuitive build in Data List Editor dialog:
1. To access the "Data List Editor":
a) Select "Baseband > Custom Digital Mod > Data Source > Data List"
b) Select "Select Data List"
