Save System Analyzer Contents

Save Button Save the contents of the System Analyzer window using the save button in the toolbar or by right-clicking on any group or signal. The following dialog opens:

Save window

Using the Save button in the toolbar, you can select the signals that you want to save (see above). Using the context menu item, you can only save the current context.

In the Save dialog:

  • set the export file type: Comma Separated Value (CSV) or Tabulator Separated (TAB)
  • specify a file name and path. As default, the project path is used and the file name "SystemAnalyzer_Export.csv".
  • limit the number of lines per file when exporting the data, using Lines per file: (for example File1.csv, File2.csv, ...)

Click OK to save the data.


  • While saving, use the Cancel button to stop the export and close the file:

Data format of the exported file

The columns in the exported file carry the following format:

Item Unit Description
Time Seconds Shows the current program time
Core Clock Hz Measured core clock in Hertz
Current A Measured current in Ampere
Voltage V Measured voltage in Volts
Data Watch Group N/A Value of the given variable
Exceptions Group Seconds Duration of the exception in seconds
Event Recorder Hexadecimal number Event record number
RTX5 RTOS Group Seconds Duration of the thread event in seconds


Consider the following example:
