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 10.8,
"Using the File Manager", on page 298.
