in
the
SA
VE
menu
displays
the
softkeys used
to copy
les.
The GPIB
command FILC
is also
available to
copy
les
.
Note
When
you
copy
les
using
this
function,
use
the
same disk
format type
for both
the
memory
disk
and
the
exible
disk.
This
copy
function cannot
copy les
when
the
format
of
the
memory disk
is dierent
from the
format of
the
exible
disk.
File
Types And
Data Saved
Binary
Files
and
ASCII
Files
The
analyzer
supports
two
le
formats
,
binary
and
ASCII,
that
are
used
to
save
data on
a
disk.
Binary
les
are
used
to
save
measurement
conditions and
data using
the SA
VE
function
and
to
retrieve
binary
data
using
the
RECALL
function.
External controllers
and Instrument
BASIC
can
read measurement
data from
binary data
les
.
ASCII
measurement
data
or
screen
image
les
can be
read by
commonly
available
IBM
PC
based
software
for
data
analysis
or
other
secondary
functions.
The RECALL
function
cannot
read
ASCII
les
.
Note
When
saving
internal
data
arrays,
note
that
ASCII
data
les
cannot
be
recalled
on
the
analyzer
.
If
you
need
to
recall
the
data,
save
the
le
in
binary
format.
This
binary
data
can
be
recalled
and
saved
as
an
ASCII
le
at
any
time
.

The
internal

that
are
stored
in
the
analyzer's
memory
consists of
the
following
six data arrays
. See \Data
Processing" for complete information on each data array and their
relationships.(Binary and ASCII Files)
Raw data arrays
contain raw
, uncalibrated
measurement data.
Calibration Coecients arrays
contain the expanded calibration coecients obtained
by
calibration of the network analyzer
.
Data arrays
contain the calibrated data obtained using the calibration coecients
.
Memory arrays contain the memory data arrays obtained using the DATA ! MEM operation.
Data Trace arrays contain the formatted data.
Memory Trace arrays contain the formatted data of the \memory arrays."
These arrays can be saved selectively to suit the application. For example, when measuring
several devices with the same measurement settings, you may need to save only the trace
