0 – 9 . Digit and decimal point buttons are used for numeric input.
+/– The +/– button toggles the sign of a number from positive to negative or from negative to
positive.
Enter The Enter button completes entry of a value.
Cancel This cancels a pending action.
BKSP The backspace button is active during entry of a number. When pressed, it deletes the
currently selected digit.
A waveform has multiple numeric parameters that define its characteristics. If a parameter is selected
via a bezel button, the value becomes highlighted on the LCD screen. At that point, pushing any keypad
button will activate the numeric input mode. A cursor indicates the currently selected digit.
In numeric input mode, the bezel menus show units that are appropriate for the value. By pressing one
of the bezel buttons, the unit becomes attached to the number, and numeric input is completed.

► Knob and Arrow Keys
When entering or editing a numeric value, the left and right arrow keys move an underline cursor to
select a specific digit within the number. The rotary knob can then be used to either increment or
decrement the value of the selected digit.
Note: Using the knob and arrow keys is optional. Numbers can be entered directly with the keypad.
