Remote command:
[:SOURce<hw>]:BB:DM:PRAMp:ATTenuation on page 904
In Baseband Only
Restricts power ramping to the baseband signal.
"Off"
Level attenuation is affected via the attenuator stages in the RF sec-
tion; only the remaining part is attenuated in the baseband. The sig-
nal is issued at the RF output with the defined level values.
"On"
Level attenuation is affected in the baseband only.
Note:
This setting is mandatory in the following cases:
●
When only the baseband signal is issued at the I/Q outputs
It is thus ensured that, with power ramping active, this signal is
output with the defined level values.
●
In case of two-path instruments, when one baseband signal is
applied to two RF paths.

4.6.3.7 Data List Editor
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 access the "Data List Editor" dialog:
1. Select "Baseband > Custom Dig Mod > Data Source > Data List"
2. Select "Select Data List"
3. Navigate to the required directory.
Select "New" and enter a filename.
