Specifying a Basic Trigger

The default analyzer triggers are
While storing "anystate" TRIGGER on "a" 1 time
Store "anystate"
for state analyzers and
TRIGGER on "a" > 8 ns
for timing analyzers. The oscilloscope triggers separately from the
logic analyzers. If you want to simply record data, these will get you
started. They can quickly be tailored by specifying a particular pattern
to look for instead of the general case.
Customizing a trigger generally requires these steps:
Assign terms to both analyzers
Define the terms
Change the trigger to use the new terms
The oscilloscope can be used in complex triggering sequences
managed by the logic analyzer, but its inherent trigger mechanism is
much simpler. Using the oscilloscope in conjunction with one or both
of the analyzers is covered in "Arming and Additional Instruments" in
this chapter. The different modes of triggering the oscilloscope are
covered in "The Scope Trigger Menu" in Chapter 7.
