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.
