5.6.2 Selecting Delay mode (OD-411/OD-415)
When delay time is ON, the displayed output is delayed for a defined
amount of time from the trigger point. Using the delay function is useful for
observing an area of the waveform that occurs some time after the trigger
point. Delay time is only supported with the
OD-411/OD-415 .
With Delay On the expansion point and trigger point become separated
by the amount of delay time. As the delay time is increased the trigger point
moves left from the expansion point. When the horizontal scale is adjusted,
the waveform expands from the expansion point, not the trigger point.
Figure 17.-
With Delay Off the expansion point and trigger point are always in the
same position. Thus when the horizontal scale is adjusted, the waveform
expands from the trigger point.
