Move Motor

The main purpose of the widget, 7.24, is to align a motor by moving it forth and back while watching a signal. And it is possible to change the slew rate.

The description of the menu bar items:

• File
  • Spectra: start the Spectra CLI
  • Write .fio file
  • Postscript: creates a Postscript file and sendd it to the printer defined by the environment variable PRINTER
  • Postscript A6: created a DINA6 Postscript file and sendd it to the printer defined by the environment variable PRINTER
  • SpectraGraphic to Clipboard: copies the graphics window to the clipboard, from where it can be pasted to other applications.
