File Name (File Name)
You can set the common file name that is used when the auto naming feature is turned off or when the auto
naming feature is set to Numbering. The maximum number of characters that you can use for file names and
folder names is 32 characters. The following restrictions apply.
• The following types of characters can be used: 0 to 9, A to Z, a to z, _, −, =, (, ), {, }, [, ], #, $, %, &, ~, !, `,and @.
@ cannot be entered consecutively.
• The following exact strings cannot be used due to MS-DOS limitations:
AUX, CON, PRN, NUL, CLOCK, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9, COM1, COM2,
COM3, COM4, COM5, COM6, COM7, COM8, COM9
• Keep the full path name (absolute path from the root folder) within 255 characters. If this is exceeded, an
error will occur when you perform file operations (save, copy, rename, create folder, etc.). When an operation
is being performed on a folder, the full path is up to the name of the folder. When an operation is being
performed on a file, the full path is up to the name of the file.
The following additional restrictions apply when you use the file name auto naming feature.
• If you set auto naming to Numbering, the file name will be the common name that you specify as the file name
with a four-character sequence number.
• If you set auto naming to Date (date and time), the characters that you entered for the file name will not be
used. File names will only consist of the date information.
Comment (Comment)
You can add a comment that consists of up to 120 characters when you save a file. You do not have to enter a
comment. All characters, including spaces, can be used in comments.
Waveform Data Save Conditions (Waveform Save Setup)
Data Format (Format)
Set the data type to binary, ASCII, or MATLAB.
• Binary (Binary)
• The sampled data stored to the acquisition memory is saved to a file in binary format. The extension is
.WDF. A thumbnail file is also saved at the same time. The thumbnail file can be viewed in the File Property
screen.
• You can load the saved binary format data into the instrument, display the waveform of the data, and view
the values that it contains. Accumulate is always set to OFF for loaded data.
• The instrument numbers of the DL350 and following modules are saved as file properties.
720211, 720250, 720254, 720268, 720266, 720281, 720221, 720241
The instrument numbers of other modules are not saved.
• ASCII (ASCII)
• The sampled data stored in the acquisition memory is converted using the specified range and saved to a
file in ASCII format. The extension is .CSV. You can use the file to analyze waveforms on your PC.
• You cannot load this type of data into the DL350.
