Preface
This document helps customers with data security concerns to sanitize or remove memory devices from the PPG3000 or
PPG3200 Series Programmable Pattern Generators or the PED3200 Series Programmable Error Detectors.
These products have data storage (memory) devices and 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 a
non functioning instrument.
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:
PPG3001, PPG3002, PPG3004 Programmable Pattern Generators
PPG3201, PPG3202, PPG3204 Programmable Pattern Generators
PED3201, PED3202 Programmable Error Detectors
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.
PPG3000/PPG3200/PED3200 Series Declassification and Security Instructions iii

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. 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. The user can write to the memory device during normal instrument operation, using the instrument
interface or remote control.
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 standard instrument and listed options.
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 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.

Clear the SD Card NOTE. The SD Card is the only location where user data is saved after turning the instrument off.
The following steps delete the instrument setup files and user pattern data files and loads the factory default parameters.
The steps involve touching soft keys on the touch screen through the graphical user interface.
1. Touch the UTIL soft key.
2. Touch the SAVE SETUP soft key.
3. Touch the DEFAULTS soft key.
4. Touch the FILE MGMT soft key.
Follow the on-screen procedure to delete all user instrument setup files.
5. Touch the PATTERN soft key.

Clear and sanitize procedures
6. Touch the FILE MGMT soft key.
Follow the on-screen procedure to delete all user pattern data files.
The instrument should now have the factory default parameters loaded and all user instrument setup files and all user
pattern data files should be deleted.
7. Power off the instrument.
Nonvolatile recovery
information
No recovery from a clear is needed as the nonvolatile clear procedure does not erase or change factory calibration constants
and the instrument firmware is not impacted. There is no standard sanitization procedure as it requires partial disassembly
of the instrument that is only permitted by factory authorized personnel.
