Configuration and operation of list mode signals
The parameters configuring the RF signal are defined in a list (table) and stored in a
file.
Creating and handling lists
List files can be created in the following ways:
●
Internally
Use the build-in table editor with columns for the frequency-level values pairs and
the dwell time.
Define the values manually (row by row) or automatically, based on value range
and step size.
(See
Lists are saved as files with user-definable filename and the predefined file exten-
sion
*.lsw
. To load a saved file, use the "File Manager".
Chapter 10.8, "Using the file manager"
●
Lists can be exported, too. For example, to exchange configuration between instru-
ments or to modify the file content with an external program and reload them again.
●
Externally
Create a list file as a CSV file with Microsoft Excel, with a Notepad or a similar tool
and save it with the predefined extension. Transfer the file to and load it into the
instrument.
Dwell time mode
You can choose whether you want to use different dwell times or a fixed value for all
steps in the list mode:
●
"From List"
This mode uses the values from the data table.
See
●
"Global"
This mode processes the list with a fixed time interval you can set with
.
List processing mode
The R&S
SMM100A generates signals from list files in two modes, "Live" and "Learned
(Frozen RF Settings)". These modes differ in terms of signal quality, signal processing
and switching time.
