Online Help
All the information from the operating manual can be shown on the display of the
R&S
DDF205 after pressing the HELP key (or F1 for users of an external GUI).
This key is used to open the online help system. The "Help Assis-
tant" dialog supplies context-sensitive help, i.e. information related
to the context within which the HELP key is pressed (e.g. if HELP is
pressed while scanning, then scan-related help-pages will appear; if HELP is
pressed while conducting ITU measurements, then ITU-related help-pages will
appear).
