Agilent Technologies HP 83711A - To Use Previously Stored Level Correct Data

T
o
Use
Previously
Stored
Level Correct
Data
When
the level
correct routine
is
run,
the
synthesizer
creates
a
table
of
correction
values for
each frequency
point
in
the
table
.
Up
to
four
level
correction
tables can
be stored
in the
synthesizer
memory
.
If
the
current
signal
path at
the synthesizer
output (the
external
signal
path)
is
identical
to
the
external signal
path on
which a
level
correct
routine
had
been
previously
run,
the level
correction
table
can
be
recalled
from
memory
and
be
used
at
a
later
time.
1.
V
erify
that
the
current
external
signal
path
is
correct
for
the
level
correct
table
you
want
to
recall
from
memory
and
use
.
The
current
external
signal
path
must
be
identical
to
the
external signal
path
that
was calibrated
and stored
in the
level correct
table
that
you
wish
to
recall.
If
the
current external
signal path
is
dierent,
the
data
can
cause
inaccurate
output
power
levels
at the
output of
the
external
signal
path.
