Preface
This document describes how to clear or sanitize the data storage (memory)
devices in the products listed below. The instructions also describe how to
declassify an instrument that is not functioning. These procedures are useful for
customers with data security concerns.
Products This document applies to the following components of the SPG8000A Master
Sync / Clock Reference Generator:
SPG8000A base generator
Option DPW (second hot-swappable redundant (backup) power supply)
Option GPS (GPS master clock synchronization)
Option PTP (IEEE 1588 Precision Time Protocol support)
Option BG (2 channels of composite NTSC/PAL black or HD tri-level
outputs, plus 2 channels of composite NTSC/PAL test signal outputs)
Option SDI (2 channels of SD/HD SDI test signal generation on 2 outputs
each), includes Option 3G (3G SDI format support) and Option DBT (Dolby E
audio stream generation support)
Option AG (DARS output; 2 AES/EBU channels plus 4 audio tone outputs; 8
AES/EBU channels)
Required documents To perform the procedures in this document, you will need to have access to the
SPG8000A manuals listed below. These manuals are available on the Tektronix
Web site at www.tek.com/downloads.

Preface
Terms The following termsmaybeusedinthisdocument:
Clear. This removes data on media/memory before reusing it in a secured
area. All reusable memory is cleared to deny access to previously stored
information by standard means of access.
Erase. This is equivalent to clear.
Media storage/data export device. Any of several devices that are used to
store or export data from the instrument, such as a USB port.
Nonvolatile memory. Data is retained when the instrument is powered off.
Power off. Some instruments have a “Standby” mode, in which power is
still supplied to the instrument. For clearing data, putting the instrument in
Standby mode does not qualify as powering off. For these products, you must
either push a rear-panel OFF switch or remove the power source from the
instrument.
Remove. Thisisaphysicalmeanstoclearthedatabyremovingthememory
device from the instrument. Instructions are available in the product Service
Manual.
Sanitize. This eradicates the data from media/memory so that the data cannot
be recovered by other means or technology. This is typically used when
the device is moved (temporarily or permanently) from a secured area to a
nonsecured area.
User-modifiable. The user can write to the memory device during normal
instrument operation, using the instrument interface or remote control.

To delete presets and user
files from memory
Backup existing presets or user files. If you want to backup your presets or user
files before you delete them so that you can restore them at a later time, perform
the following steps. Otherwise, proceed to step 12.
1. Connect a USB drive to the SPG8000A generator.
2. Press the SYSTEM buttontoselectSYSTEM : PRESET.
3. Verify the status of the USB drive:
a. Press the up (▲)ordown(▼)arrowbuttontoselectSYSTEM : USB
(status).
b. Verify that the USB status is Mounted.
c. If the status is Not Mounted, press the ENTER button to mount the USB
drive.
4. Press the up (▲)ordown(▼) arrow button to select SYSTEM :
BACKUP/RESTORE.
5. Press the left (◄)orright(►) arrow button to select one of the following:
Backup Presets to USB: Backs up only the instrument presets to the USB
drive. If you are backing up only presets, you will need up to 1 MB of
free space on the USB drive.
Backup All User Data to USB: Backs up all user data to the USB drive.
When all user data is backed up, every user file except for the FPGA
configuration files will be copied to the USB drive. 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 picture files, logo
files, sequence files,andforOptionSDIandOption3G,canalsoinclude
text and font files. The user data files do not include the application
software or any Linux files.
NOTE. If you are backing up all of the user data in the instrument, you will
needupto96MBoffreespaceontheUSBdrive.
6. Press the ENTER button to start the selected backup operation.
7. A warning message is displayed asking you to verify the operation. Press the
ENTER button to proceed or press the BACK button to cancel the operation.

8. Monitor the progress of the file copy operation:
a. During the first stage of the copy process, the display shows the names
of the filesast
hey are copied. Depending on the size of the files being
copied, this may take a couple of minutes.
b. When all of the files have been copied, the message “Finishing copy...” is
displayed while the file system buffers are emptied. This message may
appear for a couple of minutes.
c. When the backup operation is complete, the message “Backup completed
successfully” is displayed before the menu display returns to normal.
NOTE. If the USB drive runs out of memory before the backup operation
is complete, the operation will copy as much data as it can and will then
display an error message stating that the backup operation was incomplete
because the drive or device is full. Press the ENTER or BACK button to clear
the error message.
9. After the backup operation is complete, press the up (▲)ordown(▼) arrow
button to select SYSTEM : USB (Mounted).
10. Press the ENTER button to unmount the USB drive. After the message “You
may now safely remove the USB drive” is displayed, the menu readout should
change to SYSTEM : USB (Not mounted).
11. Remove the USB drive from the instrument.
Delete the presets and user files from the instrument.
12. Connect the instrument and a computer using an Ethernet connection as
described in the SPG8000A Installation and Safety Instructions.
13. On the computer, open an FTP client such as Windows Explorer.
14. In the Windows Explorer command box, enter “ftp://IP address”, where IP
address is the network address assigned to the TG8000 generator.
NOTE. Some FTP clients may ask for login credentials. In this case, login with a
user name of “anonymous” and no password.

15. The Windows Explorer window should immediately connect to the instrument
and show the directory structure as shown below.

16. In the CPUdirectory, delete any preset files.
17. In the SEQUENCE directory, delete any sequence files.
18. In each of the module directories, delete all of the preset files and any
user-created picture, logo, text, or signal files.
NOTE. In addition to the user-created files, the module directories will also
contain the factory default files for the standard signals and logos that are
supplied with the instrument. You do not need to delete the factory default files.
19. After you have deleted the desired files, close the FTP window.

Troubleshooting
How to clear or sanitize a nonfunctional instrument
To sanitize a nonfunctional instrument, remove the Main board,
GPS/Genlock/Black board, SDI board, and all Power Supply modules, and then
return the instrument to Tektronix for installation of new boards and modules.
How to recover from clearing or removing memory from the instrument
The procedure to recover from clearing or removing memory depends on whether
the memory was on a generator card or on the instrument mainframe. Perform
the appropriate procedure as described in this section.
To recover from clearing or
