Pre and Post Trigger Data Capture
You can define one set of patterns for capture prior to the occurrence of a trigger and
another set of patterns for capture after the occurrence of a trigger. The selection and
setup procedure is the same for both Pre‐Trigger capture and Post‐Trigger capture.
Check Define different patterns for pre‐trigger and post‐trigger data capture to enable
the Pre‐Trigger Capture and Post‐Trigger Capture tabs (instead of only the Capture tab).
