Sequence Trigger
Sequence trigger lets you trigger the oscilloscope after finding a sequence of events.
Defining a sequence trigger requires three steps:
1 Define an event to find before you search for the trigger.
The “find” event can be a pattern, an edge from a single channel, or the combination
of a pattern and a channel edge.
2 Define the trigger event.
The “trigger on” event can be a pattern, an edge from a single channel, the
combination of a pattern and a channel edge, or the nth occurrence of an edge from a
single channel.
3 Set an optional reset event.
If you choose to define a “reset” event, the event can be a pattern, an edge from a
single channel, the combination of a pattern and a channel edge, or a timeout value.
