Waveforms to Be Saved
• You can save all the waveforms or the selected waveform from CH1 to CH4(2),
Math1, and Math2 (or CH1 CH2, and -Math1 on the DL1720E).
• The setup data including vertical axis, horizontal axis, and trigger of the waveform to
be saved is also saved.
• For waveforms that are loaded using the history memory function, you can select
whether to save all of the history waveforms or save just the current displayed
waveform on the screen. You can also save only the results obtained by searching
the history waveforms. For a description of searching the history waveforms, see
section 10.2 or 10.3.
• For a description of snapshot waveforms, see section 12.7.
Range of Waveform to Be Saved
You can select the range (area) of a waveform to be saved. Only the data that has been
saved by selecting Binary in the aforementioned section “Data Type and Extension” can
be loaded into the instrument.
• Main:
The range of the normal (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.
• Z1&Z2:
The range of zoom waveforms Z1 and Z2.
Data Compression
• You can select whether to P-P compress the waveform data before saving.
• Power spectrum computation data cannot use P-P compression.
Storage Medium and Directory

window. Display Examples of Storage Media

Auto Naming
When Auto Naming is turned ON, files with a four digit number from 0000 to 2399 (0000
to 1199 for binary format) are automatically created when saving the data. You can
specify a common name (up to ten characters, specified through Filename) that is placed
before the number.
File Name and Comment
• A file name must be assigned. Comments are optional.
• You cannot save to a file name that already exists in the same directory (overwriting
not allowed).
