SPG8000A User Manual 17
Only presets that have content are copied or written by the backup/restore
processes. This is because only presets that have been saved have files associated
with them and the backup/restore process copies only those files. Any preset that
has never been saved will not have an associated file and therefore will not be
copied.
All user data
When all of the user data is copied, every user file except for the FPGA
configuration files will be copied. This function is useful in that all user - created
files can be saved, restored, or copied to other SPG8000A instruments.
User files are defined as any file that exists in the /app/F0 directory on the
instrument. The files in this directory can include presets, signal files, frame
pi cture files, logo files, sequence files, and for Option SDI, can also include text
and font files. The user data files do not include the application software or any
Linux files.
Memory requirements
It is recommended that you use the Flash Memory readout in the System button
menu to determine how much memory is available on the instrument before you
perform a restore operation. You can also go to the Status submenu of the System
menu in the Web interface to see the amount of free and used space. Find how
much m emory is required:
• If you are backing up or restoring only presets, you will need up to 1 MB
of free space on the USB drive or in the flash memory of the instrument.
• If you are backing up or restoring all of the user data in the instrument, you
will need up to 96 MB of free space on the USB drive or in the flash
memory of the instrument.
If the backup or restore operation runs out of memory on the USB drive or the flash
memory on the instrument before the operation is complete, the operation will copy
as much data as it can and will then display an error message stating that the
backup or restore operation was incomplete because the drive or device is full.
