Keypad
The keypad is used to enter alphanumeric parameters. It contains the
following keys:
●
Alphanumeric keys
Enters numbers and (special) characters in edit dialog boxes. For
details refer to
Chapter 3.4.3.1, "Entering Numeric Parameters"
Chapter 3.4.3.2, "Entering Alphanumeric
●
Decimal point
Inserts a decimal point "." at the cursor position.
●
Sign key
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 3.4.3.3, "Navigating in Dialog Boxes"
