Type of key Description
Sign key Changes the sign of a numeric parameter. In the case of an alphanu-
meric parameter, inserts a "-" at the cursor position.
Unit keys
(G/n dBμV, M/μ μV, k/m mV and
x1 dB(m))
These keys add the selected unit to the entered numeric value and com-
plete the entry.
In the case of level entries (e.g. in dB) or dimensionless values, all units
have the value "1" as multiplying factor. Thus, they have the same func-
tion as an [Enter] key.
3.2.1.6 Navigation controls
The navigation controls include a rotary knob, navigation keys, and the display keys.
They allow you to navigate within the display or within dialog boxes.
Rotary knob
The rotary knob has several functions:
●
Increments (clockwise direction) or decrements (counterclockwise direction) the
instrument parameter at a defined step width in the case of a numeric entry.
●
Moves the selection, e.g. to a function block in the block diagram
●
Shifts the selection bar within focused areas (e.g. lists).
●
Acts like the [Enter] key, when it is pressed.
●
Opens a context-sensitive menu, when it is pressed and held.
editing keys
Editing keys enable you to confirm an entry, delete individual characters, or exit the
current operation.
Table 3-7: Editing keys
Type of key Description
[Esc] key Closes all kinds of dialog boxes, if the edit mode is not active. Quits the
edit mode, if the edit mode is active. In dialog boxes that contain a "Can-
cel" button it activates that button.
For "Edit" dialog boxes the following mechanism is used:
●
If data entry has been started, it retains the original value and
closes the dialog box.
●
If data entry has not been started or has been completed, it closes
the dialog box.
[Enter] key
Has the same effect as pressing the rotary knob
●
Concludes the entry of dimensionless entries. The new value is
accepted.
●
With other entries, this key can be used instead of the default unit
key.
●
In a dialog box, selects the default or focused element.
●
Calls the next dialog level.
●
Confirms and closes open input windows.
[Backspace] key Deletes the character to the left of the cursor in editing mode.
