SMARTTriggers
SMARTTriggersaredefinedasfollows:
Glitch

GlitchtriggerisasimplerformofWidthtrigger.UseGlitchtrigger
whenyouwanttodefineafixedpulse‐widthtimeortimerange
only.Glitchtriggermakesnoprovisionforvoltagelevelsor
ranges.
Interval

WhileGlitchtriggerperformsoverthewidthofapulse,Interval
triggerperformsoverthewidthofaninterval:thesignalduration
(theperiod)separatingtwoconsecutiveedgesofthesame
polarity(positivetopositiveornegativetonegative).Useinterval
triggertocaptureintervalsthatfallshortof,orexceed,agiven
timelimit.Ina
ddition,youcandefineawidthrangetocapture
anyintervalthatisitselfinsideoroutsidethespecifiedrange,i.e.
itcanbeusedasanExclusiontriggerbyinterval.
Dropout

Usedprimarilyinsingle‐shotapplications,andusuallywithapre‐
triggerdelay,Dropouttriggercandetectlostsignals.Thetrigger
isgeneratedattheendofthetimeoutperiodfollowingthelast
triggersourcetransition.Youcanselectatimeoutperiodfrom
2nsto20s.
Runt

Therunttriggerisprogrammedtooccurwhenapulsecrossesa
firstthresholdlineandfailstocrossasecondthresholdline
beforerecrossingthefirst.Youcanselectbothvoltagethresholds
withinatimerangeof100psto20s.Otherdefiningconditions
forthistriggeraretheedge(triggersontheslopeoppositeto
thatselected)andr
untwidth.
SlewRate

Slewratetriggeractivatesatriggerwhentherisingorfallingedge
ofapulsecrossestwothresholdlevels:anupperlevelanda
lowerlevel.Thepulseedgemustcrossthethresholdsfasteror
slowerthanaselectedperiodoftime.Youcanselectboth
thresholdswithinarangeof2nsto20s.
