Since version 2.9 of vna/J a command-line version of the vna/J GUI is available (I call this version also headless).

This command-line version can be used to execute automated scans, when no GUI is needed or graph-ical screen output is available.

Details can be found in the user guide for the headless application.


You can buy the author a beer to support the further development of vna/J.
