3. With Delay set to On, the trigger point is disconnected from the expansion
point. Turn the Horizontal Position knob to move the trigger point away
from the expansion point (center graticule). The amount of delay is shown in
the Horizontal Status area at the bottom-center of the graticule, referenced to
0 s (center graticule).
The trigger point can move off the screen; when this happens, the trigger
marker changes to show the direction of the trigger point.
4. Once you are displaying a waveform area of interest at the center of the
screen, adjust the Horizontal Scale knob to acquire more points for the area
of interest, and use the controls to view more detail.
5. Push the Set Horizontal Position to 0s side-menu button to return the trigger
point to the center of the waveform record (setting delay to 0). Pushing this
button does not turn off the delay mode.
You can also push the front-panel Horizontal Position knob to return the
trigger point to the center of the waveform record.
Trigger Delay is different than Trigger Holdoff. See Holdoff trigger mode on
page 46.
