Note that you have to create a pulse train file first.
●
Externally
Create a pulse train sequence as a CSV file with Microsoft Excel, with a Notepad
or a similar tool, save it with the predefined extension. Transfer the file to and load
it into the instrument.
Pulse train ASCII file format
Files describing pulse trains are simple files in text or comma-separated value (CSV)
file format. The filename is user-definable; the file extension is *.csv or *.txt.
The file contains a list of pulse definition values, one row per pulse; a new line indicator
separates the pulses. Pulses are defined with their pulse on time, pulse off time given
in us and number of repetitions.
Example: Pulse train file content (*.txt file)
0.0001,0.0005,2
0.00025,0.0005,1
0.0001,0.0003,3
For file handling, use the standard functions in the "File Manager", see Chapter 11.8,
"Using the file manager", on page 324.
