AccessingSerialDecodeTriggers
Serialtriggerscanbeaccessedintwoways:
• TouchtheTriggerDescriptorBoxinthelowerrighthandcornerofthe
oscilloscopedisplay.

OR
• TouchTrigger→TriggerSetupfromtheMenu Bar.OntheTriggerdialog,
touchSerialontheTypesection.
Selecttheappropriateserialtrigger.Themenuautomaticallychangestoa
differenttabintheTriggerdialogreflectingtheselectedstandard.
