5.5.4.2 Pulse Train Generation
In "Pulse Train" mode, the instrument provides the associated parameters for configur-
ing a user-defined pulse train signal.
A pulse train is a sequence of pulses with user-defined on and off times. The "ON
Time / OFF Time" value pairs are defined in a pulse train table and can be stored in a
file. The currently loaded file is displayed in the dialog. You can export an internally
created pulse train list as well as import an externally created one.
In remote control mode, you must first create a data file, before you switch to pulse
train mode. Otherwise you get the error message "No current list" in the "Info" line, see
Example "Generating a pulse train signal" on page 389.
How to configure a pulse train signal
To perform pulse train generation, perform the following steps:
1. In the block diagram, select "Modulation > config... > Pulse Modulation".
2. Select "Source > Pulse Generator".
3. Select "Pulse Mode > Train".
The instrument displays the parameters required for configuring pulse train data.
4. Select "Pulse Train Data... > New List / Select List or File Manager".
5. Navigate to the target directory and select an existing file, or create a new file by
assigning the "File Name".
6. According to your selection, confirm with "Save" or "Select".
The R&S SMB automatically uses the new file for further editing. Pulse train data
files have the fixed file extension *.pulstrn.
