Preface
Preface
This document helps customers with data security concerns to sanitize or remove memory devices from the Tektronix
BERTScope BSA Series Bit Error Rate Analyzers.
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 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:
BSA85C
BSA125C
BSA175C
BSA260C
BSA286C
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.
vi Tektronix BERTScope BSA Series Declassification and Security Instructions

Preface
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. 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. 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 and sanitize procedures
Clear or sanitize the CMOS
settings
The computer carrier board contains a jumper that can erase CMOS data and reset the system BIOS information. To
access this jumper, you need to disassemble the instrument.
1. Refer to the procedures to remove the chassis from the instrument enclosure. (See page 14, Disassemble the
instrument.)
2. Locate the CMOS jumper J102 on the carrier board as shown in the following figure.
Figure 1: Location of J102 on the carrier board
3. Temporarily place a jumper across J102 to drain the residual voltage frm the CMOS memory.

Clear and sanitize procedures
4. Remove the jumper from J102.
NOTE. If you need to remove the hard disk drive from the instrument for security purposes, do so before reassembling the
instrument.
5. Refer to the procedures to reinstall the chassis in the instrument enclosure while being careful not to damage any circuit
boards or cables. (See page 15, Reassemble the instrument.)
Clearing hard disk drives If your organization's security protocols allow the use of software to purge or sanitize hard drives, you can use commercial
software to erase free space on the hard drive before sending the instrument out for upgrades or repair. Follow the
instructions that come with the software to ensure that the erasure of sensitive data from the hard drive complies with your
organization's security protocols.
