Period Trigger (Enhanced)
This is available only in scope mode.
The instrument triggers on a specified period of occurrence of state condition B. The instrument triggers when
state condition B occurs again.

Trigger Source
You can use CH1 to CH6 and Bit 1 to Bit 8 as the trigger sources. Bit 1 to Bit 8 appear as options when
• When a logic input module is installed in a slot.
• When the logic input terminal (CH5 or CH6) of this instrument is in use.
State Condition (B State)
To set state condition B, select the states of the trigger sources in relation to the trigger level.

Example
H: The signal level must be high.
L: The signal level must be low.
X: The signal is not used as a condition.
Trigger Level (Level) and Trigger Hysteresis (Hys)
Set these items for each trigger source.
These items are the same as the trigger level
and hysteresis of the simple trigger.
Determination Mode
Set what kind of relationship must be established between period T and the specified reference times (Time or
T1 and T2) for the instrument to trigger.
T < Time Period T must be shorter than the reference time (Time).
T > Time Period T must be longer than the reference time (Time).
T1 < T < T2 Period T must longer than reference time T1 and shorter than reference time T2.
T < T1, T2 < T Period T must be shorter than reference time T1 or longer than reference time T2.
Reference Times (Time, T1, T2)
You can set the reference times (Time, T1, and T2) within the following ranges.
Setting Selectable Range Resolution
Time 0.02 μs to 10000000.00 μs (10 s)
0.01 μs T1 0.02 μs to 9999999.99 μs
T2 0.03 μs to 10000000.00 μs (10 s)
