The Compare Menu
Difference Listing Field
The controls that roll the listing in all three menus, the normal State listing,
the Reference listing, and the Difference listing are synchronized unless the
number of pretrigger states differ between the Reference listing and the
acquired data.
This means that when you change the current row position in the Difference
listing, the analyzer automatically updates the current row in the acquired
State listing, Reference listing and vice-versa.
If the three listings are synchronized and you re-acquire data, the Reference
listing may have a different number of pretrigger states depending on the
trigger criteria. The Reference listing can be resynchronized to the State and
Difference listings by entering the desired state (acquisition memory)
location from the front-panel keypad.
This allows you to view corresponding areas of all lists, to cross check
alignment, and to analyze the bits that do not match.
