5.5.2 Reference Trigger
This trigger mode is suitable for finite point acquisition. In this mode, the
user needs to set up the number of pre-trigger samples and total samples.
And then user can acquire the data before and after trigger as shown in
Figure 33. The default number of pre-trigger samples is 0.
Example
⚫
Total samples: 1000
⚫
Pre-trigger samples: 10
⚫
Number of samples after trigger: 990 (1000-10)

5.5.3 Re-Trigger
PCIe/PXIe-6301 series products support re
-
trigger mode. Show In Figure
34.In the retrigger mode, you can set the number of retriggers and the
length of each acquisition. Assuming that the number of re triggers is n
and the length of each trigger acquisition is m, the length of all acquisition
data is n * m * channelcount.
When the number of re triggers is - 1, it is infinite.
