Chapter 3: Using the Logic Analyzer in Timing or State Mode

Setting Up Triggers and Running Measurements

State and transitional timing analysis trigger definitions are made

simpler with a default storage qualifier. This makes it possible to

ignore, at all trigger sequence levels, the question about what to do

with the captured data samples.

Of course, sometimes it's useful to specify storage qualifiers at certain

levels in the trigger sequence. For this, you can insert storage actions

in the trigger sequence before trigger or goto actions. Storage actions

in the trigger sequence override the default storage qualifier for the

samples that cause the trigger or goto actions to occur. Storage actions

can also be used to turn on or off the default storing.

Using Trigger Functions

Many common measurement setups are provided with the logic

analyzer. These setups are called trigger functions, and you can use

them for quick measurement setup.

For more complicated timing mode measurements, where no trigger

function exists, start with a trigger function that's similar to the

measurement you want to make. Then, break down the trigger

function and edit the advanced trigger specification.

NOTE: In the 16760A logic analyzer, you cannot break down trigger functions in the

400, 800, 1250 and 1500 Mb/s state mode configurations.
