11.6 Saving/Loading Waveform Data
CAUTION
• Never remove the disk or turn OFF the power while the drive is processing the
insertion of the disk or while saving (“Access...”). The media may be damaged.
Function
Savable data
• The currently displayed waveform on CH1 to CH16, Math1 to Math8. However,
accumulated waveforms cannot be saved.)
• You can save waveform data displayed from history memory, using the history memory
function.
If Display=One : Save waveform data for selected record (Selected Record No.) only.
If Display=All : Save waveform data for all records from Start Record No. to End Record
No.
• The current vertical axis, horizontal axis and trigger settings

axis and trigger settings
* Number of records : One when the acquisition mode is averaging mode
Number of the waveform data selected with “Display” of the History
menu when the acquisition mode is other than the averaging mode
Waveforms which can be saved
All waveforms which are currently displayed can be saved. Therefore, all waveforms currently
displayed can be saved while accumulation of multiple records is performed in the sequential
memory or history memory. However, no snap shot or histogram waveform can be saved. In
addition, waveforms on the channels which are used when computation is ON are also saved,
irrespective of whether their displays are ON or OFF.
Auto Naming
If “Auto Naming” is on when the waveform data are being saved to the medium, a file number
(from “000” to “999”) is automatically assigned. It is possible to insert a common file name
(character string consisting of up to five characters) before the assigned file number. The
common file name is set in the file name menu.
File name and comment
A file name must be provided, but it is not necessary to provide a comment. For details refer to
page 4-2.
Select the data range to save
Select from the following. To save the realtime recorded waveform data, see the next page
“Saving/Loading the realtime recorded waveform data.”
All
: Save the entire record length of data.
Main : Save the display record length (the range displayed on the screen) of data.
Z1
: Save the portion displayed in the Z1 zoom waveform display frame.
Z2
: Save the portion displayed in the Z2 zoom waveform display frame.
Data that are saved using “Z1” or “Z2” may display an incomplete waveform when it is loaded.
This is because data can be saved in any length, but loading can be done only in fixed amounts
of the record length.
