Sequence Trigger configuration menu
Use Sequence trigger to trigger on a second (B) event after a first (A) event occurs. You can trigger on the first occurrence of event B (with
or without a time delay), or trigger after a specified number of B events occur.
To open the Sequence trigger configuration menu:
1. Double-tap the Trigger badge on the Settings bar.
2. Set the Trigger Type to Sequence.
Note: You can select sequence triggering when you choose the slope type Falling or Rising — but not when you pick the slope
type Both.

Description
Coupling
Sets the trigger coupling.
Edge and Sequence triggering can use all available coupling types: DC, AC, Low Frequency Rejection,
High Frequency Rejection, and Noise Rejection. All other trigger types use DC coupling only.
A Source
Selects the source of the first (A) event trigger.
If the A event does not occur, no trigger event is generated.
B Source
Selects the source of the second (B) event trigger.
If the A event occurs but the B event does not occur, no trigger event is generated.
A Level
Sets the A trigger level.
B Level
Sets the B trigger level.
Set to 50%
Sets the trigger level to 50% of the applied signal.
After the A Trigger Event is
found: Trigger on the 1st B
event
Sets the oscilloscope to trigger on the first occurrence of the B event trigger conditions.
After a Delay of:
Sets a time delay condition for the Trigger on 1st B event condition. The oscilloscope waits the
specified time period after the A event before detecting and triggering on the B event condition.
Available when After the A Trigger Event is found = Trigger on the 1st B event.
After the A Trigger Event is
found: Trigger on the Nth B
event
Sets the B trigger event to wait for a specified number of trigger events before generating a trigger.
Where N is:
Sets the number of B trigger events that must occur before triggering the oscilloscope.
Available when After the A Trigger Event is found = Trigger on the Nth B event.
Mode & Holdoff
Trigger Mode determines how the instrument behaves in the absence or presence of a trigger event.
Holdoff sets the amount of time the oscilloscope waits after a trigger event before detecting and
triggering on the next trigger event.
