Changes the sign of a numeric parameter. In the case of an alphanumeric parame-
ter, inserts a "-" at the cursor position.
●
Unit keys (GHz/-dBm MHz/dBm, kHz/dB and Hz/dB)
These keys add the selected unit to the entered numeric value and complete the
entry.
In the case of level entries (e.g. in dB) or dimensionless values, all units have the
value "1" as mulitplying factor. Thus, they have the same function as an ENTER
key. The same is true for an alphanumeric entry.
●
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 "Cancel" 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.
●
BACKSPACE key
– If an alphanumeric entry has already been started, this key deletes the charac-
ter to the left of the cursor.
– If no input field is currently active, the most recently entered value is undone,
i.e. the previous value is retrieved. Thus, you can toggle between two values
(e.g. spans).
●
ENTER key
– Concludes the entry of dimensionless entries. The new value is accepted.
– With other entries, this key can be used instead of the "Hz/dB" unit key.
– In a dialog box, presses the default or focused button.
– In a dialog box, activates the edit mode for the focused area, if available. For
details on the edit mode refer to Chapter 2.4.3.3, "Navigating in Dialog Boxes",
on page 79.
– In a dialog box, activates or deactivates the selected option of the focused
area, if the edit mode is active.
