4.6.3.3 Trigger delay
The trigger delay field allows the user the set the amount of pre- or post-trigger
data that should be used when positioning the data acquisition window with
respect to the trigger moment.
POST-TRIGGER DELAY
A positive trigger delay value means the acquisition window is delayed by the
amount of time specified. In this case, the actual trigger moment itself is no
longer present in the acquisition buffer. This situation is shown in Figure 4-41
where a 20 ms trigger delay is used after triggering on phase A = 180°. The
fundamental frequency of the output is 50 Hz. The dashed line indicates the
trigger point. It occurs on the first 180-degree point that occurs after the user
presses the ENTER key while on the START field. Once the trigger occurs, the
acquisition holds off the specified 20 ms at which point the data requested is
captured. Using a positive trigger delay value always yields post trigger data.
Figure 4-41: Positive Trigger Delay (Post Trigger Data)
Positive trigger delay values may be set from 0.0 ms to 1000.0 ms (1 second)
in 0.1 ms increments. The value may be entered directly from the keyboard or
using the knob.
