Preface
This document helps customers with data security concerns to sanitize or remove memory devices from their instrument.
This series of instruments contains an open architecture PC with removable mass storage. You can order additional
removable mass storage devices to swap in and out of the instrument as needed for security reasons.
These products have data storage (memory) devices and data export interfaces (USB ports, Ethernet, and eSATA). These
instructions describe how to clear or sanitize the memory devices and disable the data output interfaces. The instructions
also describe how to declassify an instrument that is not functioning.
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
Products
The following Tektronix products are covered by this document:
• MSO64B
• MSO66B
• MSO68B
Terms
The following terms may be used in this document:
•Clear. This eradicates 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. A device that is used to store or export data from the instrument, such as a USB
port/USB flash drive.
•Sanitize. This removes the data from media/memory so that the data cannot be recovered using any known technology.
This is typically used when the device will be moved (temporarily or permanently) from a secured area to a nonsecured
area.
•Scrub. This is equivalent to sanitize.
•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.
•User Accessible. User is able to directly retrieve the memory device contents.
•User-Modifiable. The memory device can be written to by the user during normal instrument operation, using the
instrument user interface or remote control.
•Volatile memory. Data is lost when the instrument is powered off.
•Non-user-accessible 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 must
remove the power source from the instrument.
•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.

Memory device table terminology
The following terms are used in the tables in this section:
•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 or 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.
Memory devices
