The Compare Menu
State Compare is a software postprocessing feature that compares bit-
by-bit the acquired state data listing and a reference listing. State
Compare is only available when at least one analyzer is configured as a
State analyzer.
The comparison between the acquired state listing data and the data in
the reference listing is done relative to the trigger points. This means
that the two data records are aligned at the trigger points and then
compared bit-by-bit.
Any bits in the acquired data that do not match the bits in the compare
image are treated as unequal.
You can separately view the acquired data, the reference listing, and a
listing that highlights the bits in the acquired data that do not match
the corresponding bits in the reference listing.
You can edit the reference listing for unique comparisons.
You can mask specific bits that you do not want to compare. These
"Don’t compare" bits can be specified individually for a given label and
state row, or specified by channel across all state rows.
You can select a range of states to compare. When a range is selected,
only the bits in states on or between the specified boundaries are
compared. Also, you can save the reference listing along with the
analyzer configuration to disk.
