Preface
If you have data security concerns, this document helps you to sanitize or
remove memory devices from the Tektronix MDO4000 Series Mixed Domain
Oscilloscopes and Modules.
The MDO4000 Series 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 flashmemoryor
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

Terms The followingtermsmaybeusedinthisdocument:
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.
Demo setups. These setups come loaded in the instrument, and cannot be
modified by the customer.
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 remove the power source from the instrument.
Protected user data area. Contains data that is protected by a password.
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. The user can modify the data.
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.
