The analyzer
stores

numerical
data,
from
IF

.

format
(data

If
you
choose
to
save
the
raw
data
array
,
you
will
have
the most
exibility in
modifying the
recalled
measurement
(including
the
ability
to
view
all
four
S-parameters).
This
is
because
the
raw
data
array
has
the
least
amount
of
processing
associated
with
it.
Conversely
,if
you choose
to
save
the
format
array
,
your
modication
of
the
recalled
measurement
will
be
limited
by all
the
processes
that
are
associated
with
that
measurement
result.
However
,
the
format
array
is
appropriate
if
you
want
to
retrieve
data
traces
that
look
like
the
currently
displayed
data.
