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, with linearly interpolated
values, calculated 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 9.8, "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.
●
"Global"
This mode processes the list using a fixed time interval.
With "Global" dwell time you, however, still need to enter the dwell time values in
the data list.
The reason is that the instrument stores only completed rows and ignores incom-
plete entries. In addition, the data list must be filled completely, in case you want to
change the dwell time mode to "From List".

5.4 Significant Parameters and Functions
This section provides some basic parameters, settings and functions that affect the
operating modes CW, list and sweep, that means at all frequency and level transitions
of the RF signal.
Dwell time
Dwell time is the length of time that elapses from the beginning until the end of a step.
It applies to "Auto", "Single" and "Extern Single" modes, that are triggered either con-
tinuously or manually.
