State/Edge qualified: Triggers on any input source only if a given state (or transition) has
occurred on another source. Delay between sources is selectable by time or number of
events.
Dropout: Triggers if the input signal drops out for longer than a selected time out between

Pattern: Logic combination of 5 inputs (3 on 2 channel models); Each source can be high,
low or don't care. Trigger entering or exiting the pattern.

20 s or on intermittent faults.
Signal or Pattern Interval: Triggers on intervals selectable between 10 ns and 20 s
Slew Rate: Triggers on edge rates; select limits for dV, dt, and slope. Select edge limits
between 2.5ns and 20s.
Runt: Positive or negative runts defined by two voltage limits and two time limits
selectable between 2.5 ns and 20 ns
