Basic Triggers
Edge
Triggers when signal meets slope (positive, negative, or either) and level
condition.
TV-Composite Video
Triggers NTSC or PAL with selectable line and field; HDTV (720p, 1080i,
1080p) with selectable frame rate (50 or 60 Hz) and Line; or CUSTOM with
selectable Fields (1-8), Lines (up to 2000), Frame Rates (25, 30, 50, or 60
Hz), Interlacing (1:1, 2:1, 4:1, 8:1), or Synch Pulse Slope (Positive or
Negative).
Window Trigger when signal or exits a window defined by adjustable thresholds.
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 source 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. Delay 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 200
ps (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 200 ps (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.
