Manual trigger key
A dedicated manual trigger key can be used.
Simple trigger
Trigger source
CHn (select an input channel), EXT, LINE, or Time
Trigger slope
Rising, falling, or rising or falling
Time trigger
Date (year, month, and day), time (hour and minute), and time interval (10 seconds to 24 hours)

Trigger type
A -> B(N):
After the trigger A conditions are met, the DL850/DL850V triggers when the
trigger B conditions are met N times.
Count:
1 to 10000
Condition A:
Enter/Exit
Condition B:
Enter/Exit
A Delay B:
After the specified amount of time elapses after the trigger A conditions are met,
the DL850/DL850V triggers when the trigger B conditions are first met.
Time:
0 to 10 s (resolution: 10 ns)
Condition A:
Enter/Exit
Condition B:
Enter/Exit
Edge on A:
While the trigger A conditions are met, the DL850/DL850V triggers on the OR of
multiple trigger source edges.
Condition A:
True/False
AND:
The DL850/DL850V triggers on the AND of multiple state conditions.
OR:
The DL850/DL850V triggers on the OR of multiple trigger source edges or
states (or Window triggers)
Pulse Width:
B>Time:
The DL850/DL850V triggers when the time from when the trigger B conditions
are met to when they change from being met to not being met is greater than
the specified time.
Time:
20 ns to 10 s (resolution: 10 ns)
B<Time:
The DL850/DL850V triggers when the time from when the trigger B conditions
are met to when they change from being met to not being met is less than the
specified time.
Time:
20 ns to 10 s (resolution: 10 ns)
B Time Out:
The DL850/DL850V triggers when the trigger B conditions continue to be met
for the specified period of time.
Time:
20 ns to 10 s (resolution: 10 ns)
B Between:
The DL850/DL850V triggers when the period during which the trigger B
conditions continue to be met is within the specified time range.
Time
T1: 10 ns to 9.99999999 s
T2: 20 ns to 10 s (resolution: 10 ns)
Period:
The DL850/DL850V triggers when the period meets one of the following
conditions.
T>Time:
The DL850/DL850V triggers when the period of the trigger T conditions is longer
than the specified time.
Time:
20 ns to 10 s (resolution: 10 ns)
T<Time:
The DL850/DL850V triggers when the period of the trigger T conditions is less
than the specified time.
Time:
20 ns to 10 s (resolution: 10 ns)
T1<T<T2:
The DL850/DL850V triggers when the period of the trigger T conditions is within
the specified time range.
Time:
T1: 20 ns to 10 s (resolution: 10 ns)
T2: 30 ns to 10 s (resolution: 10 ns)
T<T1, T2<T:
The DL850/DL850V triggers when the period of the trigger T conditions is
outside of the specified time range.
Time:
T1: 20 ns to 10 s (resolution: 10 ns)
T2: 30 ns to 10 s (resolution: 10 ns)
Window:
The DL850/DL850V triggers when the trigger source enters or exits the range of
two specified levels.
The DL850/DL850V can trigger on the OR of the window triggers of multiple
channels.
Wave Window:
This trigger is for monitoring power supplies.
The DL850/DL850V creates templates in real time by comparing 1, 2, or 4
cycles directly preceding the current waveforms using a tolerance value,
compares the current waveforms to the real-time templates, and triggers if one
of the current waveforms falls outside of its real-time template.
• The trigger A and B conditions can be set to High, Low, or Don’t Care for each channel. The AND
of the conditions (the parallel pattern) is used to determine the result.
• For OR and AND, the condition can be set to High, Low, IN, OUT, or Don’t Care for each channel.
