The Trigger Sequence - HP 1660CS-Series User Manual

The Trigger Sequence

HP 1660CS-series logic analyzers have triggering and data storage
features that allow you to capture only the system activity of interest.
Understanding how these features work will help you set up analyzer
trigger specifications that satisfy your measurement needs.
In both the state and timing analyzers, the trigger sequence acts as a
filtering mechanism, with a minimum of two steps and a maximum of
twelve steps in the state analyzer and ten steps in the timing analyzer.
Some trigger macros may use more than one step. The steps are the
sequence level specifications. The analyzer searches for a trigger
sequence by matching input values on the pods to branch conditions,
which control transitions between sequence levels. You can insert or
delete levels to make the trigger sequence as simple or complex as
needed for your application.
