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.
