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

predefined trigger function or a user-level trigger function. The total

trigger specification can contain both kinds of function.

See Also "Using the Trigger Menu" on page 70 for more on setting up a trigger.

Sequence level usage

Generally, you would think using one function in one sequence level

uses up one of the available sequence levels. This may not always be

the case. Some of the more complex predefined functions 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 function, and the remaining available levels, are shown

within the function library list. User functions, however, use only one

level almost all the time. The only instance where multiple levels are

used with the User function is when the "<" duration is assigned.
