Triggering

As you begin to understand a problem in your system, you may realize that certain conditions must occur before the problem occurs. You can use sequential triggering to ensure that those conditions have occurred before the analyzer recognizes its trigger and captures information.

You set up sequential triggering as follows:

Select the Trigger menu for the module you are using.

In the Trigger menu, define terms and associated values to be used when searching through the sequence.

In the Trigger menu, select the number of the state sequence level you want to modify, and enter the appropriate store qualification, sequence-advance specification, and sequence-Else specification.

If you aren’t familiar with the trigger menus, try working through the examples in the Logic Analyzer Training Kit manual, or refer to the User’s Reference for your analyzer.
