Triggering the Instrument With Logic Signals (Logic Trigger)
3
Click each of the signals under [Trigger pattern] to set a logic-trigger pattern.
The logic-trigger pattern can be set.
X
Ignores a signal.
0 The logic-trigger condition of each logic signal is satised when the signal is at a low
level.
1 The logic-trigger condition of each logic signal is satised when the signal is at a high
level.
Setting example
The logic-trigger conditions differ depending on the combination of the [Condition satised]
setting (logical OR or AND operation) and the [Trigger pattern] setting as follows:
Lx1 [1]
Lx2 [0]
Lx3 [X]
Lx4 [X]
Lx1 [1]
Lx2 [0]
Lx3 [X]
Lx4 [X]

Triggering the Instrument at Regular Intervals (Interval Trigger)
5.8 Triggering the Instrument at Regular Intervals
(Interval Trigger)
Start triggers can be activated at specied intervals. Setting the recording mode to [Repeat] allows
the instrument to record waveforms at regular intervals.
• When using the pre-trigger, the instrument starts monitoring interval-trigger times after the rst
pre-trigger time elapses since the start of measurement.
• No start triggers are activated by any interval triggers while the instrument is lling the pre-trigger
memory. An interval trigger triggers the instrument while the instrument is waiting for a trigger
after the instrument has lled the pre-trigger memory.
• Since the clock is internally corrected, displayed trigger times may not synchronize with the
intervals of the interval trigger.

Click [Interval trigger].
The interval trigger setting dialog box will appear.
2
Click [Interval trigger] to set it to [On].
3
Click the [h], [min], and [s] boxes, and then enter a period of time for interval triggers.
An internal trigger is generated at the start of measurement, and triggers are repeatedly generated at the
specied intervals.

Triggering the Instrument at Regular Intervals (Interval Trigger)
Acquiring data at regular intervals (relation between a time interval and a
recording length or recording time)
The instrument is not triggered until having acquired data that has the specied recording length or
recording interval.
When a recording length or recording time is
shorter than a time interval
When a recording length or recording time is
longer than a time interval
The instrument records the specied recording
length or recording time of the data.
