Text Verbose
The text verbose format is an ASCII file format that uses alphanumeric
characters to represent the waveform. You can load text files into a word
processing program.
Text verbose waveforms have the file extension .TXT. You may notice that
text files use about three times more disk space than files stored to a disk
using the internal format. Figure 8-3 shows an example of the text verbose
format.
Waveform data normally consists of Y-axis voltage data. A versus waveform
has both X-axis and Y-axis values. Figure 8-4 shows an example of a versus
waveform. You can create a versus waveform by selecting Versus as the
Operator in the Math menu.
When a text waveform is read back into the oscilloscope, the header
information can be in any order. On a versus waveform, make sure that the X
data is listed before the Y data in the waveform text file. Because the
oscilloscope converts all characters to uppercase, the header information can
be a mix of uppercase and lowercase characters. Also, 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."
If you have modified the header information and a header field is omitted, the
oscilloscope sets that field to the default value. The default values are listed
with the descriptions of each header field. 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 floating
point number.
"Header information is not valid"
An error was detected in the
header information. This error occurs if one of the header fields or the
header data is incorrect.
