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
