The delay time reference point changes:
•
For a time reference setting of Left, the delay time is measured from
the trigger to the left-hand edge of the delay window (the marker
location).
•
For a time reference setting of Center, the delay time is measured from
the trigger to the center edge of the delay window.
•
For a time reference setting of Right, the delay time is measured from
the trigger to the right-hand edge of the delay window.
Figure 21 shows the time reference position set to Center, with horizontal
mode set to Main and a delay setting of 15
µ
s. Thus, the trigger position is
just slightly before the middle of acquisition memory.
