Preface
If you have data security concerns, this document helps you 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
mayalsobestoredinflash 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.
Reference The procedures in this document are written to meet the requirements specified in:
NISPOM, DoD 5220.22–M, Chapter 8
ISFO Process Manual for Certification & Accreditation of Classified Systems under NISPOM

Preface
Terms 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. Any of several devices that are used to store or export data from the instrument, such as
aUSBport.
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 push 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 nonsecured area.
Scrub. The user is able to directly retrieve the memory device contents.
User-modifiable. The 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.

Clear and Sanitize Procedures
The following terms are used in the tables in this section:
Type of user info stored This column describes the type of user information that is stored in the device.
User data. Waveforms and other measurement data that represent signals that users connect to the instrument.
User settings. Instrument settings that the user can change.
Both. Both user data and user settings are stored in the device.
None. Neither user data nor user settings are stored in the device.
Method of modification This column indicates the method of modifying data:
Direct. Theusercanmodifythedata.
Indirect. The instrument system resources modify the data. The user cannot modify the data.
User accessible This column indicates whether the user can retrieve the device contents:
Ye s . The user can directly retrieve the memory device contents.
No. The user cannot retrieve the memory device contents.
To clear This column tells how to clear data from the media or memory device before reusing it in a secured area. All reusable
memory is cleared to deny access to previously stored information by standard means of access.
To sanitize This column tells how to eradicate the data from the media or memory device 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 nonsecured area.
