Trigger Example Description
Level Trigger

(p. 131)
[Level]
Recording starts (or stops) when the
input signal crosses the specified trig-
ger level (voltage).
Window Trigger

(p. 133)
[In]
Recording starts (or stops) when the
input signal enters a range defined by
upper and lower thresholds.
[Out]
Recording starts (or stops) when the
input signal exits a range defined by
upper and lower thresholds.
Pattern Trigger

(p. 134)
[1]
Measuring starts and stops when
the input signal logic switches
from Low to High.
[0]
Measuring starts and stops when
the input signal logic switches
from High to Low.
[X]
Signal is ignored. No triggering
occurs.
