In either case, the title to be edited is always associated with the highest priority
displayed waveform (see register priority chart on page 4–23). This means, for
instance, that to create a title for the B waveform, the C and D registers must be
turned off; or to edit the title of a saved waveform in the C register, all registers
containing a current sweep must be turned off. Although you can edit the title of
a saved waveform for display or plotting, only the originally saved waveform
title is retained. You can circumvent this restriction by saving the waveform and
its new title as part of a stored settings group (see Save and Recall Settings and
Displays on page 6–62); the edited title is then retained as part of the newly
saved settings/waveform, and you can delete the original or not as you choose.
When performing a screen plot, the title being edited is attached to the highest
priority waveform (even if it has a previously saved title). However, if lower
priority saved waveforms exist, their titles are correctly attached to them.
The title can be up to 31 characters on a single line, and you can only title one
display at a time. When the title mode is turned on, the left-hand readouts move
down one row to accommodate the title, even if the title field is blank. Select
item 2 to edit an existing title or to enter a new title. If the display is already
titled, the title appears in the upper left with an underscore cursor beneath the
first letter. If the display is untitled, just the cursor appears.
The characters that can be used in the title are listed below the title in three lines
arranged as follows:
H
Alphabetic characters
H
Numbers
H
Punctuation and special characters
The selected character appears in reverse video in the list and also appears above
the cursor. (In the list, <SP> indicates the space or blank character.)
To enter or edit a title, use the FREQ/MKRS knob to select a character. As you
turn the knob, the selected character moves through the list, wrapping between
the end of one line and the start of the next and between the end of the last line
and the beginning of the first.
Move the cursor left or right to a new character position with the MKR [
a
] and
MKR [
'
] buttons. When done editing, leave the cursor in its last position to
avoid an unwanted character. Delete the character to the left of the cursor by
pressing the BKSP button on the keypad. Delete the entire line by pressing [Y].
As an example, the following procedure creates a new title, TEST123:
3. Press [2] to start the title mode edit.
4. Rotate the FREQ/MKRS knob until the letter T appears.
5. Press MKR [
'
] to move the cursor one place to the right.
