Understanding Logic Analyzer Triggering

The Agilent 16715A trigger user interface

Note that a picture (which corresponds to the selected function) is provided to the right of the trigger function list.

For example, if you want to trigger when a bus pattern is immediately followed by another bus pattern, you can use the “Find Pattern2 occurring immediately after Pattern1” trigger function, shown in the following figure.

Pattern2 occurring immediately after Pattern1

Once you have selected this function, you simply fill in the names of the buses and the patterns. Contrast the previous figure with the following figure, which is the same trigger created using If/Then statements. The trigger function is easier to use because the additional details of the If/Then statements have been hidden. However, if you want to see the details, you can break down the function.
