ii 3 Series MDO Declassification and Security Instructions

Preface

This document helps customers with data security concerns to sanitize or remove

memory devices from the Tektronix 3 Series MDO Mixed Domain

Oscilloscopes.

These products have data storage (memory) devices and data output devices.

These instructions tell how to clear or sanitize the memory devices and disable

the data output devices. The instructions also tell 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.

Reference

The procedures in this document are written to meet the requirements specified

in:

■NISPOM, DoD 5220.22–M, Chapter 8

■SFO Process Manual for Certification & Accreditation of Classified Systems

under NISPOM

Products

The following Tektronix products are covered by this document:

■MDO32

■MDO34

Required documents

To perform the procedures in this document, you might need access to the

3 Series MDO manuals listed below. These manuals are available on the

Tektronix Web site at www.tektronix.com/downloads.

■3 Series MDO Service Manual (Tektronix part number, 077-1500-xx)

■3 Series MDO Technical Reference Manual (Tektronix part number,

077-1499-xx)

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.

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.
