The
logic
analyzer
must
acquire
data
from
the
target
system
in
exactly
the
same
manner
as
the
target
system
interprets
the
data
.
Therefore,
the
clock
assignments
and
voltage
thresholds
utilized
by
the
system
must
also
be
used
by
the
logic
analyzer
.
The
logic
analyzer
must
see
the
exact
information
that
the
target
system
sees
.
The
type
of
information
is
specified
in
the
analyzer
with
the
State
[Assignment]
Format

menu
.
The
State
[Assignment]
Format
Specification
menu
is
also
used
to
group
incoming
channels
and
assign
names
(labels)
to
the
groups
.
Assigning
labels
to
groups
(such
as
the
address,
data
and
status
channels)
makes
the
data
displayed
on
the
logic
analyzer
much
easier
for
the
user
to
interpret
and
analyze
.
