LOWER->
AMPCOR
(lower
limit
line
->
amplitude
corrections)
stores
a
lower-limit
line
as
amplitude
correction
values
for
a
specic
frequency
range
.
Pressing
the
softkey
replaces
any
corrections
that
were
entered
previously
and
activates
the
new
amplitude
corrections
.
The
amplitude
corrections
must
rst
be
entered
into
the
lower
limit-line
table
.
T
o
prepare
the
amplitude
corrections
for
entry
into
the
limit-line
table
,
divide
the
frequency
range
into
segments
.
Starting
at
the
lowest
frequency
point,
divide
the
frequency
range
into
segments
where
the
amplitude
either
remains
at
or
has
a
measurable
slope
.
F
or
frequency
segments
that
slope
,
record
the
frequency
and
amplitude
of
the
beginning
point
and
end
point
of
the
segment.
F
or
frequency
segments
that
are
at,
record
the
frequency
and
amplitude
of
the
rst
point
of
the
segment
only
.
Enter
these
correction
values
into
the
lower
limit-line
table
using
the
limit-line
softkey
functions
.
After
the
correction
values
have
been
entered
in
the
lower

table
,
press
the
