Chapter 4 Saving/Loading Data & Managing Files
You can save settings data or waveform data on storage media. Data will be saved in the folder indi-
cated by the cursor. By using the A/B cursor pair, waveform data can be saved partially.

Auto If no files with the same name exist, saves the file with the des-
ignated name. Otherwise, a 4-digit number is automatically
added to the beginning of the file name (default setting).
If the first character of the file name is a numeral, the
added number will continue sequentially from that number.
Serial
Unconditionally, a 4-digit number is automatically added to
the beginning of the file name. If a file with the same name
exists, saves the file, adding the 4-digit number that is in-
creased by 1.
Overwrite
Saves the file with the designated name.
Error
If a file with the same name exists, an error message will be
displayed.

• Data saved with the "Text"
option is only for loading to a
PC and cannot be loaded
back into the instrument. To
reload the data later into the
instrument, use the "Binary"
option.
• When [Memory (Int)] is
selected as storage media,
only settings data can be
saved.
• The waveform evaluation
area you have created can
be saved as a black-and-
white BMP file. Saved data
can be edited on a computer
and loaded back into the
instrument. Edit images in
black and white only.

File name
The maximum number of characters for the [Save Name] string is 123. The
maximum path length including file name is 255 characters.
About divided saving
Large quantities of waveform data can be divided and saved as multiple files.
Saving divided data creates one or more waveform files and an index (IDX) file.
Then by loading the IDX file, the data in the waveform file(s) is loaded as a
batch.
See: "Batch load of waveform data"(p.101)
Other limitations
Text format data cannot be loaded into the instrument.
