• Make sure that the full file path (absolute path from the root folder) is less than or equal to 255 characters in
length. 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.
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 128 characters when you save a file. You do not have to enter a
comment.
All characters, including spaces, can be used in comments.
Data Type (Data Type)
Set the data type to binary, ASCII, or ASCII with time information.
Binary (Binary)
The data stored to the acquisition memory is saved to a file in binary format.
You can load the data into the instrument, display the waveform of the data, and view the values that it contains.
You can use the YOKOGAWA’s Xviewer software application to analyze waveforms on your PC. For more
details, contact your nearest YOKOGAWA dealer. You can download a trial version from the YOKOGAWA
website.
• Data size
Record length (Mpoint) × 2 (bytes/point) × the number of traces (from 1 to 8)
• The extension is .wdf.
ASCII
The sampled data stored in the acquisition memory is converted using the specified range and saved to a file in
ASCII format.
You can use the file to analyze waveforms on your PC. You cannot load this type of data into the instrument.
• If the record length is less than or equal to 1.25 Mpoints, all of the waveform data can be saved.
If the record length is more than 1.25 Mpoints, the data is compressed and saved.
• Data size
Record length (Mpoint) × 10 (bytes/point) × the number of traces (from 1 to 8)
• The extension is .csv.
ASCII with Time Information (ASCII with TimeInfo.)
The time information is attached to the data stored in the acquisition memory, and this data is converted using
the specified range and saved to a file in ASCII format.
• Data size
Record length (Mpoint) × {10 (bytes/point) × the number of traces (from 1 to 8)+ 16 (bytes/point)}
• The extension is .csv.
Waveform to Save (Trace)
You can save all of the displayed waveforms (All) or select a specific waveform to save. The waveforms that you
can save are CH1 to CH4/LOGIC,* and Math1 to Math4. The vertical-axis, horizontal-axis, and trigger settings
are also saved along with the waveforms.
If you select all waveforms, only the waveforms that are displayed out of CH1 to CH4/LOGIC, and Math1 to
Math4 are saved.* CH4 or LOGIC, whichever the corresponding key is illuminated, can be selected.
History Range (History)
Of the waveforms that are selected to be saved, set which range of history waveforms to save.
• One: The single waveform that is specified with Select No. on the HISTORY menu* will be saved.
• All: All history waveforms within the range bounded by Start No. and End No. on the HISTORY menu* will be
saved. If you search for history waveforms, and then select All, only the detected waveforms will be saved.
* The menu that appears when HISTORY is pressed
