Selecting delay assigns delay as the active function. You can use the delay
knob to change the delay setting at any time, even if you are in a different
menu or when delay is not the active function. However, when delay is the
active function, you can use either the delay knob, keypad, or the entry knob
to change the delay setting.
The trigger event always occurs at time zero. When delay is set to 0, the
trigger point occurs at the delay reference point. Positive delay indicates
time after trigger (posttrigger) and negative delay indicates time before
trigger (pretrigger). For example, a delay setting of 50 ns indicates that the
trigger event occurs 50 ns after the delay reference point. Viewing pretrigger
information is a useful feature because you can see the events that led up to
the trigger event.
