TRANSIENT RECORDER
CHAPTER 10: DIGITAL FAULT RECORDER
When set to “Trigger/Re-Trigger” or “Re-Trigger Only”, the transient recorder will be re-
triggered if the signal is still asserted at the end of the trigger period. The resulting record
will contain fault data only. A re-trigger is re-generated at the end of a transient record if
the signal is still asserted and if the number of re-triggers is less than the value specified
by the
Maximum Re-Triggers
setting.
