Interval Trigger
Trigger when the times difference between the neighboring rising or falling edges meets the time limit conditions
(< =, > =, [ - - . - - ], - - ][ - - ).
When the trigger condition is set as an interval between two neighboring rising edges and it is less than the set time
value, the trigger diagram is as follows:

•
< = (less than a time value)
: Triggers when the positive or negative pulse time of the input signal is lower
than the specified time value.
•
> = (greater than a time value)
: Triggers when the positive or negative pulse time of the input signal is
greater than the specified time value.
•
[ - - . - - ] (within a range of time value)
: Triggers when the positive or negative pulse time of the input
signal is greater than the specified lower limit of time and lower than the specified upper limit of time value.
•
- - ] [ - - (outside a range of time value)
: Triggers when the positive or negative pulse time of the input signal
is greater than the specified upper limit of time and lower than the specified lower limit of time value.
Holdoff, coupling, and noise reject can be set in edge trigger, see the sections
for more details.
