To compare two listings

The Compare menu allows you to take two state analyzer acquisitions and
compare them to find the differences. You can use this function to quickly
find all the effects after changing the target system or to quickly compare the
results of quality tests with results from a working system.
In Analyzer mode, press the Run key to acquire data.

In any mode other than Analyzer, pressing the Run key has no effect. The
menus which ignore Run lack the Run field onscreen. In Analyzer mode with
Run available, the menu changes to a display menu.
Go to the Analyzer Compare menu, select Copy Listing to Reference,

and then select Execute.
The Compare menu initially is empty, but when you select Execute the data
appears.
Set up the other test that you want to compare to the first.

This can be a change to the hardware, or a different system. Do not change
the trigger, however, or all the states will be different.
Run the test again, then select the Reference listing field to toggle to

Difference listing.
The Difference listing is displayed on the next page.
