The Analyzer Trigger Menu
Trigger sequence levels
Sequence levels are the definable stages of the total trigger specification.
Individual sequence levels are assigned using either a pre-defined trigger
macro or a user-level trigger macro. The total trigger specification can
contain both kinds of macro.
See Also Chapter 4, "Using the Trigger Menu," for more on setting up a trigger.
Sequence level usage
Generally, you would think using one macro in one sequence level uses up
one of the available sequence levels. This may not always be the case. Some
of the more complex pre-defined macros require multiple sequence levels.
Keep this point in mind if you are near the limit on remaining sequence
levels. The exact number of internal levels required per macro, and the
remaining available levels, are shown within the macro library list. User
macros, however, use only one level almost all the time. The only instance
where multiple levels are used with the User macro is when the "<" duration
is assigned.
Modify trigger field
The Modify Trigger field allows you to modify the statements of any single
sequence level as well as other high-level actions like global clearing of
existing trigger statements, and adding or deleting sequence levels. Break
Down Macros/Restore Macros acts a bit differently than the others.
Break Down Macros / Restore Macros
When a pre-defined macro is broken down, the contents of that macro are
displayed in the same long form used in the User macro. If the macro uses
multiple internal levels, all levels are separated out and displayed in the
sequence levels of the Trigger menu. Once the macros in your trigger
specification are broken down, Break Down Macros changes to Restore
Macros. Use Restore Macros to restore all macros to their original structure.
