Setting Parameters R&S SMB
1407.0812.62 3.10 E-2
Setting Parameters
The R&S SMB offers several and sometimes alternative possibilities for setting parameters. Operation
is possible from the front panel, with the aid of a mouse and/or from a PC keyboard. Operation of the
R&S SMB with the aid of these control media is shown in the tables below.
Frequency and level are directly set in the header area of the display using the
FREQ and LEVEL keys.
Some of the keys trigger a direct action, e.g. the RF ON/OFF key switches the RF output on and off. An
overview of key functions can be found at the end of this chapter (see section "Legend of Front-Panel
Controls", page 3.25), a detailed description of key functions is given in chapter 4, "Instrument
Functions"
Most of the parameters are set in the menus. Menus can be opened from the function blocks of the
diagram either with the aid of the rotary knob (= Enter) on the front-panel or by a mouse click on the
Config... button.
An exception are the Setup and File menus. In the Setup menu, general settings are made which are
not directly concerned with signal generation, e.g. setting of the IEC/IEEE-bus address. In the File
menu, files and lists are managed. These menus can only be called with the
SETUP and FILE keys.
Specific settings can also be made directly in the block diagram, e.g. activating a function block by
means of the
TOGGLE ON/OFF key. Changes affecting the signal flow are immediately visible in the
graphics display.
Calling a Menu - Setting Parameters
After instrument switch-on, the cursor is always on the first function block of the diagram (default
setting). It can be moved by means of the rotary knob or the arrow keys. Clicking the rotary knob opens
the menu associated with the function block. The
MENU key opens the complete menu tree.
With the aid of the appropriate keys and softkeys, the cursor can also be moved to the header area or
the Winbar.
• The
FREQ and LEVEL keys activate the frequency or level entry fields in the header area.
• The DIAGRAM key moves the cursor to the block diagram.
• The WINBAR key moves the Winbar to the forground. The button that was active last in the Winbar is
highlighted. The associated menu is activated by clicking the rotary knob (= Enter).
• The
MENU key opens the complete menu tree, the FILE and SETUP keys the respective menus.
Menus can be closed with the CLOSE key.
• The cursor can also be moved with the ESC key. However, the function of this key depends on the
current cursor position:

The editing mode is terminated and the previous value is restored (exception: value
variations with the rotary knob cannot be cancelled).
Menu area:
The cursor is set to another menu area.
Menu:
The menu is closed and the cursor changes to the next higher control level.

first function block in the diagram.
