SMART Triggers
SMART Triggers are as follows:
Glitch Glitch trigger is a simpler form of Width trigger. Use Glitch trigger
for defining only fixed pulse-width times or time ranges. Glitch
trigger makes no provision for voltage levels or ranges.
Interval While Glitch trigger performs over the width of a pulse, Interval
trigger performs over the width of an interval: the signal duration
(the period) separating two consecutive edges of the same
polarity (positive to positive or negative to negative). Use interval
trigger to capture intervals falling short of or exceeding a given
time limit. In addition, you can define a width range to capture
any interval that is itself inside or outside the specified range, i.e.
it can be used as an Exclusion trigger by interval.
Dropout Used primarily in single-shot applications, and usually with a pre-
trigger delay, Dropout trigger can detect lost signals. The trigger
is generated at the end of the timeout period following the last
trigger source transition. You can select a timeout period from
2 ns to 20 s,
Runt The runt trigger is programmed to occur when a pulse crosses a
first threshold line and fails to cross a second threshold line
before recrossing the first. You can select both voltage thresholds
within a time range of 100 ps to 20 s. Other defining conditions
for this trigger are the edge (triggers on the slope opposite to
that selected) and runt width.
Slew
Rate Slew rate trigger activates a trigger when the rising or falling edge
of a pulse crosses two threshold levels: an upper level and a
lower level. The pulse edge must cross the thresholds faster or
slower than a selected period of time. You can select both
thresholds within a range of 2 ns to 20 s.
