6. Open the second page of the "Trigger" dialog box.

7. Set the trigger delay time. If you set a positive value, the trigger event will become
effective only after the selected period of time. The displayed trace will be shifted to
the left.
In the "Trace & Statistics" display, the physical and the delayed trigger time has
been made visible in the form of small triangles, thus allowing an interactive adap-
tation of the "Delay" parameter to the signal, see chapter 3.6.2, "Special symbols",
on page 58.
8. Enter a "Dropout" value.
The dropout time prevents the trigger system from being activated by signal excur-
sions prior to the trigger event targeted.
9. Scroll to the third page of the "Trigger" dialog box.

10. Set a "Hysteresis" value.
Setting the trigger hysteresis to a value other than 0 dB will prevent triggering from
occurring again until the measurement level has fallen below the trigger threshold
by at least this value.
11. Define a "Holdoff" time.
This parameter allows you to set the period of time during which further trigger
events (measured from the last successful triggering) should be ignored.
