The Compare Menu

Reference Listing field

The Reference Listing field is a toggle field that switches the listing
type between the Reference image listing and the Difference listing.
The Reference listing is a display of the image (or template) that
acquired data is compared to during a comparison measurement. The
boundaries of the image (or size of the template) are controlled by
using the channel masking and compare range functions. Any bits in
the reference listing displayed as "X" have been set to don't care bits
during bit editing.
When the data listing is rolled, the difference data listing and the data
listing in the Listing menu are also rolled.

Difference Listing field

The Difference Listing field is a toggle field that switches the listing
type between the Reference image listing and the Difference listing.
The Difference listing is a display of the acquired data listing with the
data that differs, if any, from the Reference listing, highlighted with
inverse video. If the base is inverse assembled symbols, the entire line
is highlighted with inverse video.
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 pre-trigger states differ between
the Reference listing and the acquired data.
