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 SPG8000 Master
Sync / Clock Reference Generator:
SPG8000 base generator
Option DPW (second hot-swappable redundant (backup) power supply)
Option GPS (GPS master clock synchronization)
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)
Option 3G (3G SDI format support; Option SDI required)
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
SPG8000 manuals listed below. These manuals are available on the Tektronix
Web site at www.tektronix.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.
