An example of a state listing with state tagging relative to the trigger is

shown below.

Absolute State Tagging

Prestore allows you to store two qualified states before each state that

is stored. There is only one qualifier that enables prestore for each

sequence level. If you select this field, you will see a pop-up with the

options Off and On . Selecting On gives you a qualifier pop-up menu

like that in figure 10-2, from which you choose the pattern range or

combination of patterns and ranges that you want to prestore.

Prestore is only available when clock period is > 60 11s. If you select

Prestore, the clock period automatically changes to > 601~ if it was

previously set to < 60 ns.

Front-Panel Reference

During a measurement, the state analyzer stores in prestore memory

occurrences of the states you specify for prestore. A maximum of two

occurrences can be stored. If there are more than two occurrences

previous ones are pushed out. When the analyzer finds a state that has

been specified for storage, the prestore states are pushed on top of the

stored state in memory and are displayed in the State Listing.
