SMART®Triggers 
State or Edge Qualified  Triggers on any input source only if a defined state or edge occurred on another input source. Delay between sources is selectable by time or events.
Dropout  Triggers if signal drops out for longer than selected time between 2 ns and 20 s.
Pattern  Logic combination (AND, NAND, OR, NOR) of 5 inputs 
(4 channels and external trigger input)
Each source can be high, low, or don’t care.
Trigger at start or end of the pattern. 
  
SMART Triggers with Exclusion Technology
Glitch  Triggers on positive or negative glitches with widths selectable from 600 ps to 20 s or on intermittent faults.
Signal or Pattern Width  Triggers on positive or negative pulse widths selectable from 600 ps to 20 s or on intermittent faults.

Pass/Fail Testing 
Test waveforms by comparing their shape to test templates and simultaneously check multiple parameters versus selectable parameter or mask limits. Pass or fail conditions can initiate actions including document to local or networked files, or email the image of the failure, saving waveforms, or send a GPIB SRQ or pulse to trigger another device.
