You can specify the desired signal level (level) and
the direction (slope) of change of the input signal in
order to apply a trigger. The options that can be set
differ depending on the function.
This can be set on the [Trig] screen, [CH] screen, and [Wave+Trg] display.

Select [Level] (level trigger) for
the trigger type.
In the following steps, use the same operation to
configure settings.
This can also be set for each chan-
nel on the [CH] screen.
(Open/confirm the setting information.)
Select the [Trig] screen.

level you want to detect in [Level] (sig

nal level)
Setting options (default setting: 0 )
4 Select the judgment item for the input
signal from the setting options of [S
(slope)].
The options that can be set differ depending on
the trigger application condition (AND/OR).
Settable range: - (minus) full scale value to +
(plus) full scale value
Full scale value = vertical axis (voltage axis) range
[V/div] x 10 div
Example: When the vertical axis (voltage axis)
range is 20 V/div:
20 V/div x 10 div = 200 V
200 V becomes the full scale value.
