Multipurpose knobs.
You can change cursor position using the position controls
in the Cursor setup window, dragging the cursor into position using the touch
screen or mouse, or by turning the front-panel multipurpose knobs.
The multipurpose knobs also work with other controls. If a setup window item
has an adjustable value, you can adjust it with the multipurpose knob or keypad
after touching the setup control.
NOTE
. To make small changes with the multipurpose knobs, push the FINE
button before turning the knob. When a FINE button is illuminated, its multipur-
pose knob makes smaller adjustments.
You must target the cursors to the source they are to measure. (See Cursors Treat
Sources Independently on page 3--163). To do so, use the procedure that follows.
