6.7 Triggering by Analog Signals
150
A trigger can be applied when the input signal crosses a specified trigger level
(voltage threshold). The direction in which the signal crosses the threshold is
specified by the trigger slope setting (rising
, falling
or both
).
6.7.2 Triggering When Crossing a Voltage Threshold
(Level Trigger)
Apply a trigger when the input sig-
nal exceeds 200 mV or falls below
–600 mV.

Procedure
1
CURSOR
Move the highlight cursor to a trigger number to
be set.
For the [Normal] setting, match the number of the
channel to which the trigger applies.
2
Select the trigger type.
CURSOR
Move the cursor to the
[Type]
item.
F1 to F8
Select
[Level]
(Level Trigger).
3
Select a channel (only with the [Expanded] setting).
CURSOR
Move the cursor to the
[Ch]
item.
F1 to F8
Select a channel to which the trigger applies.
4
Select the trigger level.
CURSOR
Move the cursor to the
[Level]
item.
F1 to F8
or
SCROLL
Specify the trigger threshold voltage.
5
Select the trigger slope.
CURSOR
Move the cursor to the
[Slope]
item.
F1 to F8
Select either choice.
A trigger occurs when the signal crosses the
threshold on the upslope (rising edge
).
(default setting)
A trigger occurs when the signal crosses the
threshold on the downslope (falling edge
).
A trigger occurs when the signal crosses the
threshold on either the upslope or downslope
(
).
Note: The trigger point occurs one sample af-
ter the criterion is met.
Timebase 2 sampling data is also one sample
later than that of Timebase 1.

200 mV
0 V

T
Trigger No.
Setting Example
Start
Measurement
T
If the signal is outside of the
specified threshold levels at
the start of measurement, no
triggering occurs.
Triggering occurs when the signal
crosses the threshold.
