Using the Logic Analyzer
Using the Analyzer Menus
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.
1 In Analyzer mode, press the Run key to acquire data.
In any mode other than Analyzer, Scope, or Patt Gen, 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.
2 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.
3 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.
4 Run the test again, then select the Reference listing field to
toggle to Difference listing.
The Difference listing is displayed on the next page.
