Trigger Example Description
Level Trigger
[Level]
(p. 150)
A trigger is applied when an in-
put signal crosses the specified
trigger level (threshold voltage).
In-Window Trigger
[Win-In]
(p. 152)
A trigger is applied when the in-
put signal enters a range defined
by upper and lower thresholds.
Out-of-Window Trigger
[Win-Out]
(p. 152)
A trigger is applied when the in-
put signal exits a range defined
by upper and lower thresholds.
Period Trigger
[Peri-In]
[Peri-Out]
(p. 153)
A trigger is applied when the pe-
riod of the input signal becomes
longer (Out-of-Period) or shorter
(In-Period) than the period de-
fined by the limits at the specified
reference voltage.
Glitch Trigger
[Glitch]
(p. 155)
A trigger is applied when the in-
put signal pulse width becomes
shorter than the specified Glitch
Width.
Slope Trigger
[Slope]
(p. 156)
A trigger is applied when the in-
put signal level matches the
specified trigger level in the
specified slope direction (rising
or falling).
Voltage Sag Trigger
[Drop]
(p. 158)
A trigger is applied when the am-
plitude of the input signal (at
commercial mains frequency)
sags below the specified trigger
level.
In addition to the above, the following criteria can be set:
• Trigger width setting (Trigger Filter) (p. 149)
• Setting the event count per trigger (Events) (p. 149)
