Clear settings with the aid of independent subdialogs
A separate window is opened for each dialog and subdialog. The dialogs can be oper-
ated independently of each other, i.e. none of the dialogs requires that settings in other
dialogs be completed before it can be closed. This ensures flexible operation at all
times.
Keys with assigned simple functions
Most keys on the front panel of the R&S SMB directly perform a simple function.
Since a great number of settings can thus be made by a keystroke, operation is easy.
For instance, the CLOSE (ESC) key closes the active menu; with the RF ON/OFF
(CTRL+R) key the RF output signal can be switched on or off.
An exception are keys that call a menu such as the MENU (CTRL+M) key which opens
the complete menu tree of the instrument, the SETUP (CTRL+E) key which opens the
menus for general instrument settings or the FILE (CTRL+S) key which opens the
menu for file management.
Help functions for user support
Numerous help functions support the user in signal configuration.
●
Value ranges
The valid setting range is displayed for each numeric parameter. This requires a
short wait after activation of the entry field. The range is then displayed automati-
cally after a few seconds.
If the entered value is outside the permissible range, the next permissible value is
automatically set and a message is output.
●
Context-sensitive help
Context-sensitive help for each parameter can be called with the HELP or F1 key.

Comprehensive online help
Each help page is part of a comprehensive online help function which can be
called by means of an index, a content tree or the "Previous/Next" buttons.
Info line with messages for indication of the current instrument state

ings or information are displayed in the header field of the screen. With the aid of the
INFO (CTRL+I) key, help pages can be called for most of the messages. They provide
