TriggerScan
TriggerScanisadebuggingtoolthathelpsyouquicklyfindrarewaveformglitches
andanomalies.WithTriggerScan,youcanbuildalistoftriggersetupstolookfor
rareeventsandautomaticallysequencethrougheachone.TriggerScancanuseany
typeoftriggersetupavailableincludingedge,width,andqualifyaswellasSmart
Triggers(su
chas,glitchandrunttriggers).TriggerScanautomatestwokey
processesintriggeringrareevents:
1. Trainsthesystembylookingatnormalacquiredwaveforms.Duringthe
training,theoscilloscopeanalyzesthewaveformstodeterminewhat
waveformsnormallylooklike.Usingthisinformation,itgeneratesalistof
smarttriggers
etupstotriggeronabnormalsituations.
2. LoadsthesmarttriggersetupsfromtheTrainerandcyclesthroughthese.
Astriggersoccur,theyareoverlaidonthescreen.Allacquisitionsettings
arepreservedandyoucanuseallthefunctionsoftheoscilloscopetofind
therootca
useoftheseanomaliesincluding,WaveScan,Histograms,and
advancedanalysis.
