Function that Saves the Data in the Internal
Memory to the External Storage Medium
There are two methods in which the data are saved to the external storage medium,
manual save and auto save.
Manual Save
The external storage medium is inserted into the drive only when storing the data
residing in the internal memory.
The data residing in the internal memory are saved to the external storage medium when
the storage medium is inserted into the drive and press MEDIA key.
Whether to store the entire data in the memory or only the data that have not been saved
is specified beforehand.
Auto Save
The external storage medium is placed in the drive at all times. Data saving to the
external storage medium is done automatically.
Note
Even in the Auto Save mode, the MEDIA key must be pressed to detect the external medium
when it is first inserted into the drive.
Displayed data
The display data in the internal memory are saved to the external storage medium at the
specified interval (auto save interval, see section 8.8).
Event data
• During the free mode
The event data in the internal memory are saved to the external storage medium at
the specified interval (data length, see section 8.11).
• During trigger or rotate mode
After acquiring the data to the internal memory over the specified period (data length,
see section 8.11), the event data in the internal memory are saved to the external
storage medium.
The following figure shows the operation when the acquisition area in the internal
memory is divided using the trigger mode.

Manual sampled data
The first time manual sample is executed, a manual sampled data file is created on the
external storage medium. The data are appended to this file for each successive manual
sample operation.
Note
If the external storage medium is not inserted, the unsaved data are saved the first time when
manual sample is executed after the external storage medium is inserted.
