The keypad is used to enter alphanumeric parameters, including the corresponding
units. It contains the following keys:
Table 3-5: Keys on the keypad
Type of key Description
Alphanumeric keys Enter numbers and (special) characters in edit dialog boxes.
Decimal point Inserts a decimal point "." at the cursor position.
Sign key Changes the sign of a numeric parameter. For an alphanumeric parame-
ter, 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.
For level entries (e.g. in dB) or dimensionless values, all units have the
value "1" as multiplying factor. Thus, they have the same function as an
[Enter] key.
[INSERT] key Toggles between insert and overwrite mode
[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.
[Backspace] key If an alphanumeric entry has already been started, this key deletes the
character to the left of the cursor.
[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.
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 for 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).
