HP 8753D - Storing Data to Disk

Storing
Data
to
Disk
Y
ou
can
use
the
internal
disk
drive
or
connect
an external
disk drive
for storage
of instrument
states
,
calibration
data,
measurement
data,
and
plot
les.
(Refer to
Chapter 4,
\Printing,
Plotting,
and
Saving
Measurement
Results",
for
more
information
on saving
measurement data
and
plot
les
.)
The
analyzer
displays
one
le
name
per
stored
instrument
state
when you
list the
disk
directory
.
In
reality
,
several
les
are
actually stored
to the
disk when
you
store
the
instrument
state
.
Thus
,
when
the
disk
directory
is accessed
from a
remote system
controller
,
the
directory
will
show
several
les
associated
with
a
particular
saved state
. The
maximum number
of
les
that
you
can
store
on
a
disk
depends
on the
directory size
.Y
ou
can
dene
the
directory
size
when
you
format
a
disk.
See
T
able
12-3 for
the default
directory size
for oppy
disks
and
hard
disks
.
The
maximum
number
of
instrument states
and calibrations
that can
reside on
a
disk
is
limited
by
the
available
disk space

In
the
upper
righthand
portion
of
the
display
,
the
value
displayed
as
Bytes free:
is
the
available
disk
space
.
If
your
disk
is
formatted
in
LIF
,
this
value is
the largest
contiguous block
of
disk
space
.
Since
the
analyzer
is
reporting
the
largest
contiguous block
of disk
space,
you
may
or
may
not
see
the
bytes
free
number
change
when
you delete
les.
If your
disk is
formatted
in
DOS,
the
number
reported
as
bytes
free
is
the
total
available
disk
space.
That number
is
updated
whenever
you
save
to
or
delete
les
from
the
disk.
A
disk
le
created
by
the
analyzer
appends
a
sux
to
the
le
name
.
(This
is
on
the
analyzer's
directory
and
is
not
visible
.)
The
sux
consists
of
one
or
two
characters:
the
rst
character
is
the
le
type
and
the
second
is
a
data
index.
(Refer
to

the
denitions
of
each
sux
character

If correction is on at the time of an external store, the calibration set is stored to disk. (Note
that inactive calibrations are not stored to disk.) When an instrument state is loaded into the
