text verbose The text verbose format is an ASCII le format that uses alphanumeric
characters to represent the waveform. You can load text les into a word
processing program.
Text verbose waveforms have the le extension .TXT.You may notice that
text les use about three times more disk space than les stored to a disk
using the internal format. Table 11-1 shows an example of the text verbose
format.

Header information
When a
text waveform
is read
back
into
the
instrument,
the
header
information
can
be in
any order
.
On
a
versus
waveform
(refer
to
the
Math
menu),
make
sure
the
X
data
is
listed
before
the
Ydata
in the
waveform
text
le
.
Because
the
instrument
converts
all
characters
to
uppercase
,the
header
information
can
be
a
mix
of
uppercase
and
lowercase
characters
.
There
must
be
at
least
one
space
between
a
header
and
its
corresponding
data.
For
example
,
there
must
be
at
least
one
space
between
\Type:"
and
\raw."
Error
Messages
If you
have
modied
the
header
information
and
a
header
eld
is
omitted,
the
instrument
sets
that
eld
to
the
default
value
.
The default
values are
listed
with
the
descriptions
of
each
header
eld.
If
the
header information
is
incorrect,
you
will
get
one
of
the
following
error messages
.
Waveform
data
is
not
valid
An error was detected in the waveform data. This error occurs if one of
the data points is not a valid oating point number.
Header information is not valid
An error was detected in the header information. This error occurs if one
of
the
header
elds
or
the
header
data
is
incorrect.
If
the
results
are
not
what
you
expected
after
reading
an ASCII
waveform
back into the instrument, the cause is that the instrument is interpreting
your data dierently than you expected. Try restoring the ASCII waveform
from the waveform memory back to the disk. By comparing the restored
data to what you had entered into the instrument, you may nd
your error.
