Save Range (Range)
You can select the waveform save range (area) from one of the choices below.
• Main window (Main): Saves the data displayed in the main window
• Zoom 1 or Zoom2 (Zoom1 or Zoom2): Saves the data displayed in the specified zoom window
• Cursor range (Cursor Range): Saves the data in the area between the cursors
Save Conditions (Waveform Save Setup)
• Waveform to Save (Select Save Trace)
• You can select All ON, CH1 to CH16,

and Math. The
waveforms you select that are displayed are saved. Even if you select All ON, only the waveforms that are
displayed are saved.
1 You can select the channel of an installed module.
2 When a 16-CH voltage input module or 16-CH temperature/voltage input module is installed. You cannot
select sub channels.
3 On the DL850EV when a CAN bus monitor module or CAN & LIN bus monitor module is installed. You
cannot select sub channels.
• The vertical-axis, horizontal-axis, and trigger settings are also saved along with the waveforms.
• Saving History Waveforms (History)
You can set the source waveform to one of the waveforms below.
• One waveform (One): Only the waveform with the record number specified in the history menu is saved.
• All waveforms (All): All history waveforms between the start and end numbers specified in the history menu
are saved.
To save an averaged history waveform, set the display mode in the history menu to Average Record, and set
History to One.
• P-P Compression (P-P Comp)
When you save waveform data in binary format, you can choose whether to use P-P compression on it.
• ON: P-P compression is used on the data before it is saved.
• OFF: The data is saved without being P-P compressed.
• Data Removal Interval (Interval)
When you save data in ASCII format, you can thin out the data before you convert it to ASCII format. Set the
data removal interval.
OFF (no data is removed), 5 points (Per 5), 10 points (Per 10), 20 points (Per 20), 50 points (Per 50), 100
points (Per 100), 200 points (Per 200), 500 points (Per 500), 1000 points (Per 1000), 2000 points (Per 2000),
5000 points (Per 5000)
For example, if you select Per 5, the data will be removed as indicated below.
First data point, +5, +10, +15...
• Time Information (Time Info.)
When you save data in ASCII format, you can choose whether to save time information.
• ON: Time information is saved.
• OFF: Time information is not saved.
• Extension (Extension)
When you save data in ASCII format, you can set the extension of the files that you save to .csv or .MATLAB.
