Once
you
have
chosen
the
proper
start
frequency
,
pressing
any
terminator
key
while
a
numeric
parameter
entry
is
not
in
progress
will
cause
the
synthesizer
to
go
to
stop
frequency
entry
mode
.

When
in
stop
frequency
entry
mode
,
the
synthesizer
will
display
COR
STOP
XXXGHZ
.
Stop
frequency
entry
is
identical
to
start
frequency
entry
.
The
stop
frequency
is
used
to
determine
the
ending
frequency
for
the
level
correction
table
.
The
stop
frequency
is
the
last
frequency
point
in
the
table
.
Once
you
have
chosen
the
proper
stop
frequency
,
pressing
any
terminator
key
while
a
numeric
parameter
entry
is
not
in
progress
will
cause
the
synthesizer
to
go
to
number
of
points
entry
mode
.

When
in
number
of
points
entry
mode
,
the
synthesizer
will
display
SET
NUMBER
OF
POINTS
XXX
.
The
number
of
points
value
determines
how
many
frequency
points
will
be
in
the
level
correct
table
.
The
number
of
points
includes
the
start
and
stop
frequency
points
.
The
synthesizer
uses
the
start
and
stop
frequency
values
and
number
of points
and places
evenly
spaced
frequency
points
in
the
level
correction
table
.Note
that if
the
calculated
frequency
points
are
not
within
the
synthesizer
frequency
resolution,
they
will
be
rounded.
Once
you
have
chosen
the proper
number
of
points
,
pressing
any
terminator
key
while
a
numeric
parameter entry
is
not
in
progress
will
cause
the
synthesizer
to
ask
if you
want
to
run
the
level
correction
routine
.

When
the
synthesizer
is
asking if
you want
to
run
the
level
correction
routine
,
the
display
indicates
RUN CORRECTION?,
HIT ENTER
.
If
you
press
the 4
Hz
5
(ENTER)) key
,
the
synthesizer
begins
collecting
new
level
correction
data.
F
or each
frequency
point
in
the
table
,
the
synthesizer
sends
the
power
meter
the
frequency,
waits for
the
meter
to
settle
,
and
then
reads
the
power
value
from
the power
meter.
As
the
correction
runs
,
the
synthesizer
calculates
the
loss
data
by
subtracting
the
power
meter
reading
from
the
current
power
level.
(The
synthesizer
power
level
is
constant
during
the
level
correct
routine.)
