Carry out steps 27 to 29 in “Saving the Waveform Data.”
Note
When a file saved by specifying Z1 (or Z2) is loaded, the data of the record length of Z1 (or
Z2) is displayed right justified.
Explanation
Selecting the Data Type
The following three data types are available.
Binary
• The sampled data in the acquisition memory is saved in binary format.
• The data that is saved (excluding the data has been P-P compressed and saved)
can be loaded and used to display waveforms and compute numeric data.
If the saved data is loaded, the accumulate setting is always turned OFF.
• A header file that is used when analyzing the waveform on a PC is automatically
created. The header file cannot be opened on the SL1400. For details on the
header file format, see appendix 5.
• The extension is .WVF. The extension of the header file name is .HDR.
• When saving waveform data in binary format, a header file is automatically created
with the .HDR extension. When the SL1400 is used to copy, delete, change
filenames, or change file attribute of waveform data files (files with .WVF
extension), the header files are automatically updated to reflect the changes. Do
not delete only the header file or only the waveform data file, as this may cause a
system malfunction.
ASCII
• The sampled data in the acquisition memory is saved in ASCII format in the unit
converted by the specified range. The data can be used to analyze the waveform
on a PC.
• The file cannot be loaded into the SL1400.
• The extension is .CSV.
• If the file size exceeds 2 GB depending on the combination of the record length
and the number of channels, the files cannot be created.
Float
• The sampled data in the acquisition memory is saved in 32-bit floating format
(IEEE) in the unit converted by the specified range. The data can be used to
analyze the waveform on a PC.
• The data is in Little Endian (Intel format).
• The file cannot be loaded into the SL1400.
• The extension is .FLD.
• If the file size exceeds 2 GB depending on the combination of the record length
and the number of channels, the files cannot be created.
