Basic Triggers
•
Edge/Slope/Line:
Triggers when the signal meets the slope and level condition.
•
Width:
Triggers on positive or negative pulse widths selectable from 500 ps to 20 s or on intermittent faults
(subject to bandwidth limit of oscilloscope).
•
Pattern:
Logic combination (AND, NAND, OR, NOR) of 5 inputs (4 channels and external trigger input – 2
Ch+EXT on WaveRunner 62Xi). 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.
•
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.
•
TV:
Provides stable triggering on standard or custom composite video signals. Use them on PAL, SECAM, or
NTSC systems. Optional HDTV Trigger for 1080i, 1080p and 720p formats along with non-standard formats
up to 2000
lines.
SMART Triggers
•
Dropout:
Triggers if the input signal drops out for longer than a selectable time-out between 1 ns and 20 s.
•
Glitch:
Triggers on positive or negative glitches with widths selectable from 500 ps to 20 s or on intermittent
faults (subject to bandwidth limit of oscilloscope).
•
Signal or Pattern Interval:
Triggers on intervals selectable from 1 ns to 20 s.
•
Runt:
Trigger on positive or negative runts defined by two voltage limits and two time limits. Select between 1
ns and 20 s.
•
Slew Rate:
Activates a trigger when the rising or falling edge of a pulse crosses two threshold levels, an
