Trigger Characteristics
A Event and Delayed B Event Trigger Types Edge, Glitch, Runt, Width, Transition Time, Time-out, Pattern, State, Setup/Hold, Window – all except
Edge, Pattern, and State can be Logic State qualified by up to two channels
Main Trigger Modes Auto, Normal, and Single
Trigger Sequences Main, Delayed by Time, Delayed by Events, Reset by Time, Reset by State, Reset by Transition. All sequences
can include separate horizontal delay after the trigger event to position the acquisition window in time
Clock Recovery System Requires Option PTH or Option MTH Standard

Enhanced Triggering User-selectable; enhanced triggering corrects the difference in timing between the trigger
path and the acquired data path (supports all Pinpoint trigger types on both A- and B-Events
except pattern trigger); Not available in FastAcq mode
