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. |
| Qualified First | In Sequence acquisition mode, triggers repeatably on event B only if a defined pattern, state, or edge (event A) is satisfied in the first segment of the acquisition. Holdoff between sources is selectable by time or events. |
| Dropout | Triggers if signal drops out for longer than selected time between 1 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. The High and Low level can be selected independently. Triggers at start or end of the pattern. |
SMART Triggers with Exclusion Technology |
|
| Glitch | Triggers on positive or negative glitches with widths selectable as low as 500ps (depending on oscilloscope bandwidth) to 20 s, or on intermittent faults. |
| Width (Signal or Pattern) | Triggers on positive, negative, or both widths with widths selectable as low as 500ps (depending on oscilloscope bandwidth) to 20 s, or on intermittent faults. |
| Interval (Signal or Pattern) | Triggers on intervals selectable between 1 ns and 20 s. |
| Timeout (State/Edge Qualified) | Triggers on any source if a given state (or transition edge) has occurred on another source. Delay between sources is 1 ns to 20 s, or 1 to 99,999,999 events. |
| Runt | Trigger on positive or negative runts defined by two voltage limits and two time limits. Select between 1 ns and 20 ns. |
| Slew Rate | Trigger on edge rates. Select limits for dV, dt, and slope. Select edge limits between 1 ns and 20 ns. |
| Exclusion Triggering | Trigger on intermittent faults by specifying the expected behavior and triggering when that condition is not met |
Cascade (Sequence) Triggering |
|
| Capability | Arm on "A" event, then Trigger on "B" event. Or Arm on "A" event, then Qualify on "B" event, and Trigger on "C" event. |
| Types | Cascade A then B: Edge, Window, Pattern (Logic) Width, Glitch, Interval, Dropout, or Measurement. Measurement can be on Stage B only. Cascade A then B then C (Measurement): Edge, Window, Pattern (Logic), Width, Glitch, Interval, Dropout, or Measurement. Measurement can be on Stage C only. Cascade A then B then C: Edge, Window, Pattern (Logic) |
| Holdoff | Holdoff between A and B or B and C is selectable by time (1ns to 20s) or number of events. Measurement trigger selection as the last stage in a Cascade precludes a holdoff setting between the prior stage and the last stage. |
