b. Numeric-Entry Edit.
Key Pad: Typing any character on the numeric keypad
will set up a 'box' beneath a smaller version of
the selected numeric value, and place the typed
character in the box. The right side key labels
change to give a choice of units.
Units: After the new value has been typed on the
keypad, the required units can be chosen from
the right side soft keys. Pressing one of these
keys will cause the display to revert to the 'Digit
Edit' format, with the same numeric value
remaining selected by the two triangles.
'Enter': The keypad 'Enter' (ø) key can be used instead
of one of the units keys to revert to 'Digit Edit'
format. In this case the 9500B firmware will
always impose the basic units (not multiples or
sub-multiples).
Further Use: Either Digit Edit or Numeric-Entry Edit can be
used for all selectable variables on the screen.

3. Scope Mode
This mode differs from Direct Mode only in that adjustment of
many screen variables is constrained to a series of 'Stepped Values',
which run in a sequence of 1 : 2 : 5 factor steps (The 'Pref' facility,
described overleaf, can be used to change the factor sequence to
match certain oscilloscopes with 1 : 2 : 2.5 : 4 : 5 steps). Selecting
one of these variables places a 'barred' cursor above and below the
whole numeric value (shown in Fig 3.2.1), and only one method of
value adjustment is available:
Cursor keys:
These forms of editing are also described in greater detail, with
illustrations, in Section 4, sub-section 4.4.
