SCOPIX Oscilloscopes IV - 83
Oscilloscope Mode (cont'd)
Trace Saving (to the non-volatile memory) or recall of a trace or a reference
memory. The back-up can be saved in two formats: ".TRC" or ".TXT".
The "File copy" menu is adapted to the type of format selected.
Save .TRC
Save.TXT
Saving of the files for subsequent recall on the oscilloscope screen
The back-up files will take the suffix .TRC; they can be recalled in the
"Trace
Recall" menu.
Saving of files for export to another application
The saved files have the suffix .TXT; they cannot be recalled by the "Trace
Recall" menu for screen display. However, they can be exported in a
standard format for use in other software (spreadsheet - e.g. Microsoft
EXCEL) using the menu "Util
Files Export".
The selection made opens a "File Copy" menu.
∗
Then in the "Source" drop-down menu, select the trace or the
reference memory to be recorded.
∗
All the channels can be saved in one operation:
A .TRC file is created for each channel displayed
A .MAC file is created: this file contains the commands needed to
restore all the channels saved.
The trace or reference memory to be saved will appear in grey. The stylus
is used for selection.
•
Only traces and reference memories present on the screen are
indicated in the "Source" list (selectable).
•
Use the scrollbar on the right of the list to view all the elements.
∗
A default backup file name is proposed above the keyboard. A file is
generated from the date and current time.
It can be modified using the
virtual keyboard with the stylus.
The key deletes the character preceding the cursor in this area.
∗
Once the name has been written, the key records it by entering it into
the destination menu and closes the menu. The backup file takes the
extension .TRC (internal format) or .TXT (text format), depending on the
previous selection.
Saving of the file is triggered with this key.
You can exit from this menu without saving by tapping with the stylus on
the icon in the top right-hand corner of the window.
•
By moving the pointer onto the names of the files, you will see their
characteristics displayed (date and time saved and size).
•
If the name already exists or is incompatible, an error message
‘Impossible! File already exists' will be displayed.
•
The filename is limited to a maximum of 20 char extension.
If this rule is not observed, the message: 'Filename too long’ is displayed.
