Understanding Logic Analyzer Triggering
The same trigger as If/Then statements
Trigger functions can be modified. For example, if you start with the
function “Find Edge”, you can add another event, and it becomes the
same as “Find Edge and Pattern”. Therefore, a function that is not
exactly correct can often be converted into the desired trigger. It is also
possible to break down a function into the underlying If/Then
statements and modify them.
The functions “Store range until pattern occurs” and “Store nothing
until pattern occurs” make storage qualification much easier. These
functions completely override the Default Storage. The “Store range
until pattern occurs” function is shown in the following figure.
Store range until pattern occurs
Trigger functions are like building blocks because they can be used
together in a trigger sequence. For example, if you want to set up a
trigger as “Find edge followed by pattern”, you can use a “Find Edge”
function for Level 1 and a “Find Pattern” function for Sequence Level 2
(see the following figure). So, functions are useful both as an entire
trigger sequence and as one step in a trigger sequence.
