Set Up the State Trigger Specification

When comparing two state listings, it is best to only sample the data you are interested in comparing. This will ensure that the errors you find are errors in the data you are interested in, rather than in the pretrigger data. Setting the analyzer to store "no state" before the trigger, tells the analyzer to begin capturing data after the trigger is found.
