ii SPG8000A Declassiﬁcation and Security Instructions

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.
