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 speci
fi
ed in:
NISPOM, DoD 5220.22–M, Chapter 8
ISFO Process Manual for Certi
fi
cation & Accreditation of Classi
fi
ed 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 declassi
fi
cation.
A term that refers to procedures that must be undertaken before an instrument can be
removed from a secure environment. Declassi
fi
cation 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.
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-modi
fi
able.
The user can write to the memory device during normal instrument operation, using the instrument
interface or remote control.
User-modi
fi
able.
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 modi
fi
ed. It means that the user can modify the data.
Indirectly – Describes how data is modi
fi
ed. It means that the instrument system resources modify the data and that
the user cannot modify the data.

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
fi
rmware 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.

Troubleshooting
Clear or sanitize a nonfunctional instrument
CAUTION.
Removing instrument covers to access internal components invalidates your warranty. Do not remove instrument
covers unless you are quali
fi
ed to do so. For additional information, contact your local Tektronix service representative.
If your instrument is not functioning and you need to clear or sanitize it, the SD card should be removed and the instrument
should be returned to Tektronix Inc. To remove the SD card, the chassis covers must be removed and the SD card must
be removed from the processor board. Please contact your local Tektronix service representative for more SD card
removal details.
The SD card is the only part of the instrument that will retain user data (such as pattern data or instrument setups) after
the instrument has been turned off.
Charges
Replacement of any missing hardware will be charged according to the rate at the time of replacement.
