Recording Rules Page: How It Works
You can think of the Recording Rules page as a workspace for creating recording rules
(rules that determine how the analyzer records traces). Recording rules are combinations
of events and actions.
In UWBTracer/Trainer terms, an event and the action or actions associated with it form a
rule state. One or more states are encapsulated in a sequence.
Note: There can be from one to 512 states within a sequence. You can associate
one or more events with each state, and you assign each event a different
action or the same action.
A sequence that has only one state is called a single-state sequence. The analyzer
continuously watches for each event in the sequence and executes the corresponding
action if the event is detected.
A sequence that has multiple states is a multi-state sequence. The states are arranged
in a hierarchy, with a top state and successively lower states. Only one state in a
multi-state sequence is active at a time. The analyzer does not go to a successive state
unless it is directed to do so by the previous state.
Sequences are described in detail in "Using Sequences" later in this chapter.
Briefly, creating a rule involves the following steps:
Step 1 Creating Event buttons in the Available Events area.
Step 2 Drag-and-drop of Event buttons to the appropriate areas (cells) in the
Main Display area.
Step 3 Assigning an action or actions to each Event button.
