Agilent Technologies HP 83711A - LVL CR

L
VL
CR
The
LVL
CR (level
correct)
function
allows
you
to
calibrate
external
path
losses
in the
signal path.
The
level
correct
function
creates
a
table
in
synthesizer
memory of
external path
loss values
versus
frequency
.
Invoking
the L
VL CR
(level correct)
function
(pressing
the
4
SHIFT
5
key and
then
the 4
INT
LEVEL
5
key) causes
the synthesizer
to prompt
you
for
the
start
frequency
, stop
frequency
,
and
number
of
points
in
the
level
correction
table
.
Once
the start
frequency
,
stop
frequency
,
and
number
of
points
are
entered,
you
are
given
the
option
of
running
the
level
correct
routine
.
When
4
SHIFT
5
,
4
INT
LEVEL
5
(
L
VL
CR
)
is
pressed,
the
synthesizer
initially
prompts
you
for
the
level
correct
start
frequency
.

When
4
SHIFT
5
,
4
INT
LEVEL
5
(
LVL
CR )
is pressed,
the text
COR
START
XXXGHZ
will
be displayed
where XXX
is
the
current
start
frequency
.
At
this
point,
a
new
start
frequency can
be
entered
or
the
existing
start
frequency
can
be
modied
using
the
knob
or
arrow
keys
.
The
start
frequency
is
used
to
determine
the
beginning
frequency
for
the
level
correction table
.
The
start
frequency
is
the
rst
frequency
point
in
the
table.
