Explanation of Functions
Period Trigger
A trigger is activated by measuring the pulse period (period from the time condition T
is met to the next time when condition T is met).
LogicA/LogicB
Disable: Do not use logic input
Enable: Use logic input
T
CH1 to CH16
L: Low level
H: High level
X: Don’t care
•T > Time
A trigger is activated when condition B is met the second time, if the time (T) when
condition B is met the second time is longer than a specified time.
When condition B: CH1=H and Time=10 µs
B is true
CH1

•T < Time
A trigger is activated when condition B is met the second time, if the time (T) when
condition B is met the second time is shorter than a specified time.
When condition B: CH1=H and Time=10 µ s

• T1 < T < T2
A trigger is activated when condition B is met the second time, if the time (T) when
condition B is met the second time is within a specified time range (T1 to T2).
When condition B: CH1=H, Time1=10 µ s, and Time2=14 µ s
