This document helps customers with data security concerns to sanitize or remove
memory devices from the listed products. These products have data storage
(memory) devices and data output devices (USB ports). These instructions tell
you how to clear or sanitize the memory devices, and also tell you how to
declassify an instrument that is not functioning.
Instrument code and calibration settings reside in nonvolatile flash memory.
Instrument setups and reference waveforms may also be stored in flash memory
or on USB drives connected to the instrument.
If you have any questions, contact the Tektronix Technical Support Center at
www.tektronix.com/support.

iv Declassification and Security Instructions
Preface
Terms used in this document
The following terms may be used in this document:
■
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.
■
Instrument Declassification. A term that refers to procedures that must be
undertaken before an instrument can be removed from a secure environment.
Declassification procedures include memory sanitization and memory
removal, and sometimes both.
■
Media storage/data export device. Any of several devices that can be 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 the purpose of clearing data, putting the
instrument in Standby mode does not qualify as powering off. For these
products, you will need to either press a rear-panel OFF switch or remove the
power source from the instrument.
■
Remove. This is a physical means to clear the data by removing the memory
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 will be moved (temporarily or permanently) from a secured area to a
non-secured area.
■
Scrub. This is equivalent to sanitize.
■
User Accessible. User is able to directly retrieve the memory device
contents.
■
User-modifiable. User can write to the memory device during normal
instrument operation, using the instrument interface or remote control.
■
Volatile memory. Data is lost when the instrument is powered off.

Preface
Device terms
The following terms are used with the memory devices in this document:
■
User data. Describes the type of information stored in the device. Refers to
waveforms or other measurement data representing signals connected to the
instrument by users.
■
User settings. Describes the type of information stored in the device. Refers
to instrument settings that can be changed by the user.
■
Both. Describes the type of information stored in the device. It means that
both user data and user settings are stored in the device.
■
None. Describes the type of information stored in the device. It means that
neither user data nor user settings are stored in the device.
■
Directly. Describes how data is modified. It means that the user can modify
the data.
■
Indirectly. Describes how data is modified. It means that the instrument
system resources modify the data and that the user cannot modify the data.
