Preface
This document helps customers with data security concerns to sanitize or
remove memory devices from the Tektronix AFG2000 Series Arbitrary Function
Generators.
All of these products have data storage (memory) devices. Some models have
data output devices (USB ports). 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 arbitrary function generator models are covered by this
document:
AFG2021
AFG2021-SC
AFG2021-BR

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.

Preface
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. Thisisaphysicalmeanstoclearthedatabyremovingthememory
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. 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
Memory devices
The following tables list the volatile and nonvolatile memory devices in the
instrument. Detailed procedures to clear or sanitize these devices, if any, are
shown following each 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 informationstoredinthedevice. Itmeansthat
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.

instrument
UsethisSecurefunction to erase confidential data from your instrument. This
procedure does not erase or change factory calibration constants.
1. Push the front-panel Utility button to display the Utility menu.
2. Push the System bezel button.
3. Push the Secure bezel button. The following message appears on the screen:
“The Secure function will erase all setups and waveforms stored in the
internal memory. Are you sure you want to execute secure function?”
4. Select OK to execute Secure. Secure does the following:
Erases all waveforms and stored setups in all user memories.
Replaces the current front-panel setup with the default factory setup
values.
Replaces the current GPIB and Ethernet settings with the default factory
settings for models with these ports.
