Delayed mode
Delayed sweep is an expanded version of main sweep. When Delayed mode is
selected, the display divides in half and the delayed sweep icon displays in
the middle of the line at the top of the display. The top half of the display has
the main sweep and the bottom half has the delayed sweep.
The area of the main display that is expanded is intensified and marked on each
end with a vertical marker. These markers show what portion of the main sweep
is expanded in the lower half. The Horizontal knobs control the size and position
of the delayed sweep. The delay value is momentarily displayed in the
upper-right portion of the display when the delay time ( ) knob is turned.
