Analog Signal Triggers
1. Level Trigger
A trigger is applied when the input signal crosses the specified trigger level (threshold voltage).

In this manual, T indicates a “trigger point,” the time at which a trigger is applied.
Type Parameters
[Level]
[L] (Level)
Sets the level (voltage value) for the trigger. (The setting can be made in 1/50
increments.)
[S] (Slope) Determines whether triggering occurs when the signal crosses the threshold (trigger
level) on the rising or falling edge. With the [ ] setting, triggering occurs in both
directions. (↑, ↓, )
[Event]
The number of signal rising or falling edge events is counted and triggering occurs
when the Event number set here is exceeded. (1 to 4000)
[F] (Filter) Triggering occurs when the trigger criteria are met within the specified filter width.
This is useful to prevent spurious triggering due to noise. ( : OFF, 0.1
- 10 div : OFF, ON*) *: Filter width 10 ms.
2. In-Window Trigger, Out-of-Window Trigger
By setting upper and lower limit values for the trigger, a trigger will be applied when the input signal enters
(In) or leaves (Out) this range.

Type Parameters

[Out]
[Lower] Set the lower limit value.
(The setting can be made in 1/50 increments.)
[Upper] Set the upper limit value.
(The setting can be made in 1/50 increments.)
[F] (Filter)
Triggering occurs when the trigger criteria are met within the specified filter width.
This is useful to prevent spurious triggering due to noise.
