Delayed sweep is an expanded version of main sweep. When Delayed mode is
selected, the display divides in half and the delayed sweep
the middle of the line at the top of the display. The top half displays the main
sweep and the bottom half displays the delayed sweep.
4 Turn the horizontal sweep speed knob and delay time knob and note
how the waveform expands, contracts, and moves on the display.
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 (
To change the sweep speed for the delayed sweep window, turn the sweep speed
knob. As you turn the knob, the sweep speed is highlighted in the status line
above the waveform display area.
The point about which the delayed sweep window is expanded is referenced to
the delay time and is dependent on the time reference setting:
• When Time Ref is set to Left, the delayed sweep expands to the right starting
from the delay time setting (one graticule from the left side of the display
when delay time = 0).
• When Time Ref is set to Center, the delayed sweep expands equally left and
right) from the delay time setting (center of the display when delay time = 0).
• When Time Ref is set to Right, the delayed sweep expands to the left starting
from the delay time setting (one graticule from the right side of the display
when delay time = 0).
To change the sweep speed for the main sweep window, press the Main softkey,
then turn the sweep speed knob.
