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 dB
μ
V, M/
μ
μ
V, 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.

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.
Editing Keys
Editing keys enable you to confirm an entry, delete individual characters, or exit the
current operation.

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-

closes the dialog box.
●
If data entry has not been started or has been completed, it closes
the dialog box.

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.
