CALIBRATION
CONSTANTS
DESCRIPTION
Table
A-3
lists the calibration
constants
with
a
description of
each.
The
values
in
the
Range
column
show
the
amount
of
adjustment possible with
the
cal
constant.
The
numbers
shown
are
the
only
numbers you
should
enter.
You
can enter
values out
of
the
given
range,
but they do
not
represent
the
values used
by
the
instrument.
The
column
labeled
Significance
gives
the
units
associated
with
the
cal
constant.
For
example,
the
value entered
for
LOCK DWELL
TIME
represents
the
number
of milliseconds
the
instrument
waits,
after
phase lock,
at
the
beginning of
a
sweep,
or
at
bandcross,
before
it
continues
its
sweep.
Another
example
is
the
ALC
9
GHz
SLOPE,
for each
count,
a
power
compensation
of
0.0025 dB/GHz
is
added
to
the
RF
output
[if
10
is
entered,
a
0.025
dB/GHz
slope
(10
times 0.0025
dB/GHz)
is
added
for
a
sweep
within
the
9
to
20
GHz
range].
Five of
the
Cal
Constants
[PRESET
OPTION
(#56),
HP-IB
ADD
&
LOCK (#57), RETRACE
DWELL
(#58),
ATTENUATOR
CONFIG
(#59),
and
CONFIGURATION
(#60)]
use
their
bit
configuration
to
store
more
than
one
piece
of
information.
For
example,
the
HP-IB
ADDRESS
sets
up
the
HP-IB
address
and
allows
or
disallows
the SHIFT
LOCAL,
SHIFT
SAVE, and
SHIFT RECALL
functions.
If
a
you
wish
to
set
up an
HP-IB
address
of
19,
disallow
the
SHIFT
LOCAL
and
RECALL
functions,
and allow
the
SHIFT
SAVE
function,
enter
179
for
Cal
Constant
#57. You
find
the
appropriate
calibration
constant
(179
in this
example)
by
adding
the
appropriate
calibration
constants
for
the
individual
functions:
19
(HP-IB
address)
32
(disallows
SHIFT LOCAL)
0
(allows
SHIFT
SAVE)
128
(disallows
SHIFT
RECALL)
"179
The
other
four
cal
constants
work
the
same
way.
