Combination (Logic)
Select the trigger source combination from one of the settings below.
AND
Allows triggering when all the trigger source signal patterns match the specified pattern
OR
Allows triggering when any of the trigger source signal patterns matches the specified pattern
Trigger Condition (Condition)
Select the condition for judging the results of comparing the trigger source signal pattern and the specified
pattern.
With a Clock Source
Enter
Detects changes in the comparison results from a mismatched condition to a matched condition
at the clock source sampling timing. The instrument triggers at the point of change.
Exit
Detects changes in the comparison results from a matched condition to a mismatched condition
at the clock source sampling timing. The instrument triggers at the point of change.
True
Detects matches in the comparison results. The instrument triggers at the clock source
sampling points while the match is true.
False
Detects mismatches in the comparison results. The instrument triggers at the clock source
sampling points while the mismatch is true.
Without a Clock Source
Enter
Detects changes in the comparison results from a mismatched condition to a matched
condition. The instrument triggers at the point of change.
Exit
Detects changes in the comparison results from a matched condition to a mismatched
condition. The instrument triggers at the point of change.
True
Detects matches in the comparison conditions. The trigger timing varies depending on time
conditions, explained later.
False
Detects mismatches in the comparison conditions. The trigger timing varies depending on time
conditions, explained later.
Time Condition (Time Qualification)
Set what kind of relationship must be established between the trigger condition achievement time and the
specified reference time (Time, Time1, Time2). You can set this when the clock source is set to None and the
trigger condition (Condition) is true or false.
More than
When the trigger condition achievement time (t) is longer than the specified reference time (Time)
Less than
When the trigger condition achievement time (t) is shorter than the specified reference time
(Time)
Inside
When the trigger condition achievement time (t) is longer than reference time Time1 and
shorter than reference time Time2.
Outside
When the trigger condition achievement time (t) is longer than reference time Time1 and
shorter than reference time or Time2
Timeout
When the trigger condition achievement time (t) is longer than the specified reference time (Time)
Reference Times (Time or Time1 and Time2)
The selectable range for Time or Time1 and Time2 varies depending on the time condition. You can set this
when the clock source is set to None and the trigger condition (Condition) is true or false.
More than
Time: 2 ns to 10 s
Less than
Time: 4 ns to 10 s
Inside
Time1: 2 ns to [10 s - 2 ns], Time2: 4 ns to 10 s
Outside
Time1: 2 ns to [10 s - 2 ns], Time2: 4 ns to 10 s
Timeout
Time: 4 ns to 10 s
Resolution: 2 ns
