Saving and Loading the Data
12
Selecting the range of the waveform to be saved
Select the range (region) of the waveform from the following choices. The only data
that can be loaded are those data that are saved by specifying [Binary] in “Selecting
the data type, file extension, data size” (described earlier) and [Main] for the range.
• Main
The range of the Main waveform. It is the range defined by the display record
length (range displayed on the screen).
• Z1
The range of zoom waveform Z1.
• Z2
The range of zoom waveform Z2.
Selecting the medium and directory
See the explanation given in “Selecting the medium and directory” in section 12.5.
File name and comment
See the explanation given in “File name and comment” in section 12.5.
Auto naming function
See the explanation given in “Auto naming function” in section 12.5.
Specifying the file to be displayed in the File List dialog box
You can specify the type of files to display.
• Item
Displays only the waveform data files (Binary, ASCII, or Float).
• All
Displays all the files on the medium.
Properties
See the explanation given in “Properties” in section 12.5.
Note
•
You cannot save or load while the data acquisition is in progress (START/STOP indicator is
ON).
•
If you change the file extension on a PC, for a example, you will not be able to load that file.
•
A maximum of 36 characters can be displayed in [Path].
•
For file names, upper and lower case letters are not distinguished. For comments, they are
distinguished. In addition, the following file names cannot be used due to limitations of MS-
DOS.
AUX, CON, PRN, NUL, CLOCK
•
When using the GP-IB or serial interface commands to enter a file name, the following
symbols that do not exist on the keyboard of this instrument can be used.
{ }
•
The waveform data loaded from a file overwrites the data in the acquisition memory. Once
the memory is overwritten, the old data cannot be recovered. It is recommended that the
current waveform data be saved before loading data from a file.
•
Even when the data type was set to [Binary], data cannot be loaded if the range of the
waveform that was saved was [Z1] or [Z2].
•
Waveform data cannot be loaded, if the record length or the module configuration differs from
the setting that existed at the time the data were saved. This is also true if the waveform data
were saved using an incompatible version of firmware.
