Disk
Disk stores the summary information to a disk. The
Store Summary menu allows you to specify the rst four
characters of the le name. The last four characters are
reserved for consecutively numbering any subsequent
summary les stored to the disk. If you select SUMM as the
rst four characters of the le name, the le name of the
summary le stored to the disk is SUMM0000.SUM. The
le name of the second summary le stored to the disk
is SUMM0001.SUM. Each subsequent time the instrument
stores a summary le to the disk, it checks which les are
already on the disk, then increments the last four digits of
the le name by one. If you change disks, the le number
starts
over
again
at
SUMM0000.SUM.
Theoretically
you
can
have
up
to
9,999 summary
les.
However
,
there
are
two
limits
that
keep
you from
obtaining
that
many
les
.
The
rst
limit
is
with MS-DOS
itself.
MS-DOS
limits
the
root
directory
to
224
entries
(an
entry
is
either
a
le
name
or
subdirectory).
Because
the
instrument
can
only
access
les
in
the
root
directory
,
that
limits
the
maximum
number
of
les
the
instrument
can
store
to
a
disk
to
224.
The
second limit
is the
potential
size
of
a
summary
le
.
The
size of
the summary
le
depends
on
how
many
measurements
are made
and the
setup
of
the
Run
Until
softkey
.
Usually
you will
not have
224 summary
les
.
However
,
if you are also storing screen and waveform information
to the disk, there is the potential to ll up the disk. If
the instrument cannot store additional les to the disk,
the header portion of the summary is still updated, but
additional logs are not appended to the summary le.
