If SDT is enabled in Setup, the SDT tab will display time measurements of detected errors/alarms specified by the user in SDT
setup.
SDT Measurement ends after the Gate time is elapsed, to allow the capture of multiple smaller events.
The total time from the beginning of the first event to the end of the last event (within the Gate Time) is the reported SD time. If
the total SDT is greater than the Limit Time, the test is considered a Fail.
The measurement process is immediately restarted in search for the next trigger. Results are presented in tabular form (Events
log) indicating SD start time (1 ms resolution or better), disruption time, and Pass/Fail evaluation. This table gets populated as
new disruptions are detected and measured.
Last SDT
: The duration of the last service disruption detected
Min/Max
: Shortest and longest service disruption duration
Result
: Waiting for trigger or Measure
Waiting for trigger: Testing is in progress and the unit is waiting to detect an error/alarm
Measure: Error/alarm is in progress
