Softkeys are assigned to the nine keys located both at the left and at the right edge of the screen. To simplify the display, only the softkeys which are actually assigned in a menu are indicated.

The CMU provides selectable and non-selectable softkeys.
A softkey is selected by pressing the associated key.
A selected softkey is highlighted by a blue frame. Softkey selection establishes a connection to settings and functions related to the softkey. These related functions can be initiated via keys (e.g. ON/OFF, CONT/HALT), or via the selected softkey itself (e.g. calling up popup menus by pressing a selected softkey again). After the function has been terminated, or after another softkey is selected, the softkey returns to its initial state. |
| Softkey types and their function: | |
 |
Softkeys perform definite tasks within the corresponding
menus. Different types of softkeys are provided:
Pressing the softkey (i.e. the associated key) causes an immediate response on the screen. An example is the non-selectable softkey Connect. Control which is used to call up a popup menu. |
 |
Pressing the softkey activates a dialog box, e.g. an input field. |
 |
The softkey is a measurement control softkey (main softkey)
indicating the measurement state (RUN, OFF, HLT). A yellow triangle
indicates that a popup menu providing configurations can be opened with
the softkey (press once for selection, a second time for opening the popup).
A measurement can be started and aborted with the ON/OFF key (i.e. the ON/OFF key switches between the measurement states RUN and OFF). It can be stopped while preserving the valid results with the CONT/HALT key (i.e. the CONT/HALT key switches between the measurement states RUN and HLT; starting a measurement from the OFF state by means of the CONT/HALT key is not possible). In the HLT state, the instrument resources are not released; the application is still available. The formal aspects of measurement control are explained in section Outline - Remote Control. |
 |
The softkey indicates the generator status (ON, OFF).
A yellow triangle indicates that a popup menu providing configurations
can be opened with the softkey (press once for selection, a second time
for opening the popup).
A generator can be started and aborted with the ON/OFF key. The formal aspects of generator control are explained in section Outline - Remote Control, section Measurement Control. |
 |
The softkey toggles between two hotkey bars (corresponding to two groups of settings). The current group is indicated in large typeface in the first line of the softkey; the alternative group appears in smaller typeface next to a double triangle. |
