The on-screen keyboard contains two sets of characters plus the following additional
controls:
●
"Shift" changes between the two character sets containing lower case letters/num-
bers and upper case letters/special characters, respectively.
●
"<= BS" deletes the current string in the alphanumeric input field.
●
"OK" applies the current selection and closes the keyboard. The current string is
written into the input field of the calling dialog. See also chapter 3.2.3.1, "Immediate
vs. Confirmed Settings", on page 63.
●
"Cancel" discards the current selection and closes the keyboard. The input field of
the calling dialog is left unchanged.
The on-screen keyboard allows you to enter characters, in particular letters, without an
external keyboard. To enter numbers and units, you can also use the DATA ENTRY keys
on the front panel of the instrument.
3.2.3.3 Step Size
A step symbol next to a numeric input field opens the "Step Size" dialog to define an
increment for data variation using the "Cursor Up/Down" buttons in the dialogs or the
rotary knob.
The input value for the step size takes effect immediately; see chapter 3.2.3.1, "Imme-
diate vs. Confirmed Settings", on page 63. "Auto" activates the default step size for the
current input parameter.
