Two types of period triggering are available:
• In-Period Trigger
[Peri-In]
By measuring the rising and falling period at a reference voltage, apply a trig-
ger when the input signal enters specified period limits.
• Out-of-Period Trigger
[Peri-Out]
By measuring the rising and falling period at a reference voltage, apply a trig-
ger when the input signal exits specified period limits.

Procedure
1
CURSOR
Move the highlight cursor to a trigger number to
be set.
2
Select the trigger type.
CURSOR
Move the cursor to the
[Type]
item.
F1 to F8
Select
[Peri-In]
or
[Peri-Out].
3
Select a channel.
CURSOR
Move the cursor to the
[Ch]
item.
F1 to F8
Select a channel to which the trigger applies.
4
Specify the reference voltage.
CURSOR
Move the cursor to the
[Level]
item.
F1 to F8
or
SCROLL
Set the reference voltage at which to measure
the period.
5
Select the trigger slope.
CURSOR
Move the cursor to the
[Slope]
item.
F1 to F8
Select either choice.
6
Set the period range (upper and lower threshold values).
CURSOR
Move the cursor to the
[Upper]
or
[Lower]
item.
F1 to F8
or
SCROLL
Set the upper and lower threshold values.
Measure the threshold period at the rising (
)
trigger slope.
Measure the threshold period at the falling (
)
trigger slope.
Apply a trigger when the input sig-
nal is outside of the range 0.9 to 1.1

About the Trigger Point
The trigger point occurs one sample after
the criterion is met. Timebase 2 sampling
data is also one sample later than that of
Timebase 1.
About period range settings (p. 154)
Using In-Period Triggering
When [Peri-In] triggering is enabled for
multiple channels with the AND trigger cri-
terion setting, a trigger event occurs only
when all input signals cross the specified
level at the same time.
