●
Sign key
Changes the sign of a numeric parameter. In the case of an alphanumeric
parameter, 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 dia-
log box.
●
BACKSPACE key
– If an alphanumeric entry has already been started, this key deletes the
character to the left of the cursor.
