220.127.116.11.1. Post-fill Count
In a custom state-based triggering flow with the segment_trigger and trigger buffer control actions, you can use the post-fill_count argument to specify a custom trigger position.
- If you do not use the post-fill_count argument, the trigger position for the affected buffer defaults to the trigger position you specified in the Setup tab.
- In the trigger buffer control action (for non-segmented buffers), post-fill_count specifies the number of samples to capture before stopping data acquisition.
- In the segment_trigger buffer control action (for segmented buffer), post-fill_count specifies a data segment.
When the Signal Tap data window displays the captured data, the trigger position appears as the number of post-count samples from the end of the acquisition segment or buffer.
Sample Number of Trigger Position = (N – Post-Fill Count)
In this case, N is the sample depth of either the acquisition segment or non-segmented buffer.
