Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from the Tektronix AFG1000 Series Arbitrary Function
Generators.
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.
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:
■AFG1022
■AFG1062

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.
■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.

Built-in security features
The AFG3000 Series Arbitrary Function Generators have the following security
functions:
■Secure
Secure
To erase confidential data from your AFG1000 Series Arbitrary Function
Generator, use the Secure function. Clear Flash procedure on page 5 It does
the following:
■Erases all user waveforms stored in all user memories.
■Secure does not erase or change factory calibration constants.

Clear and sanitize procedures
Clear Flash procedure
Use this Secure function to erase confidential data from your instrument. This
procedure does not erase or change factory calibration constants.
1. Power on the instrument.
2. Select Arab > others > File_browse.
3. Select Enter.
4. Select Secure.
The user waveforms will be erased.

Clear or sanitize a non-functional instrument
If your instrument is not functioning, perform the following actions. Refer to
your organization’s policies regarding storage or disposal of any removed items.
USB Flash drive
This is the start of your concept.
Remove any attached USB flash drives from the instrument before returning the
instrument for repair.
