Reference
Use the delay feature when you want to acquire waveform detail that is
separated from the trigger even t by a significant interval of time. For
example, you can trigger
on a sync pulse that occurs once every 10 m s
and then look at high-speed signal characteristics that occur 6 ms after
the syn c pulse.
In the next screen example, the trigger markers show that the trigger
point is before the acquired waveform. The delay time, shown in the
readout, is the time fr
om the trigger point to the expansion point (center
screen).

The interaction between delay and other functions is summarized in
the n ext table.
