If the oscilloscope is in Normal trigger mode, it automatically resets after
the B event. Arm trigger events can be set for
Edge
,
Pattern
,
State
, and
PatState
. State is briefly explained as follows:
S
TATE
The
State
trigger is a level-qualified trigger which requires that the
qualifying signal remain above or below a specified voltage level for a
trigger to occur. For State trigger, you specify the time or number of
events after the signal has gone above or below the voltage level when
you want the trigger to occur.
Smart
These are a specific set of sophisticated trigger types. Smart trigger types
are used to set conditions on signals with rare features, like the glitches
and others as follows:
W
INDOW
A smart trigger occurs when a signal enters or exits a window defined by
adjustable thresholds.
I
NTERVAL
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 that fall
short of, or exceed, 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 - an Exclusion trigger by interval.
