Preface
This document helps customers with data security concerns to clear or sanitize the following instruments:
5 Series MSO with a serial number below B020000 or C040000 and factory-installed Option 5-SEC
6 Series MSO with factory-installed Option 6-SEC
This series of instruments contain a processor system with nonremovable mass storage.
These products have data storage (memory) devices and data export interfaces (USB and Ethernet). These instructions
describe how to clear or sanitize the memory devices and disable the data output interfaces. The instructions also describe
how to sanitize an instrument that is not functioning.
Reference
Supported products
The procedures in this document are written to meet the requirements specified in:
National Industrial Security Program Operating Manual (NISPOM), DoD 5220.22–M, Chapter 8
Defense Security Service Manual for the Certification and Accreditation of Classified Systems under the NISPOM
Tektronix 5 Series and 6 Series Mixed Signal Oscilloscope products are covered by this d ocument:

Preface
About the option
Option 5-SEC and 6-SEC provide the highest level of instrument security for the products. Option features include:
Oscilloscope hardware is configured to easily declassify the oscilloscope:
No user access to the internal m.2 storage to store or save any user data to the oscilloscope memory. Data can only
be saved to or read from a USB port on the instrument, a mounted network drive, or through the programmatic
interface
The optional Windows OS solid state drive cannot be installed, because the hard drive connection bracket is
not available in the instrument
Password protection to enable/disable external USB Host, USB Device and Ethernet communication ports
Password protection to enable/disable firmware upgrades or downgrades
PasswordprotectiontopreventBIOSmodification and booting from USB flash devices.
NOTE.
iv Declassification and Security Instructions
Option 5-SEC and 6-SEC must be ordered at the same time you order an instrument.

How to clear or sanitize a nonfunctional instrument
An instrument with this option only stores user instrument settings, last waveform acquisition data, port-enable passwords,
and Ethernet IP settings on the instrument. Do the following to clear or sanitize your instrument if it is not functioning
and must be returned to Tektronix for repair:
1.
Remove all external USB memory devices and store or destroy the USB memory devices in accordance with your
organization’s guidelines.
2.
Follow the instructions in section Carrier interface assembly removal instructions to get access to the rear chassis
and remove the carrier interface assembly. Store or destroy the carrier interface assembly in accordance with your
organization’s guidelines. (See page 10.)
3.
Reassemble the instrument without the carrier interface assembly and return it to Tektronix. The instrument will
then be repaired and calibrated as necessary.
In North America, contact the Tektronix Customer Care Center (1-800-833-9200) for assistance with returning the
instrument to a repair center. Worldwide, visit www.tektronix.com to find contacts in your area.
Carrier interface assembly removal instructions
Use these procedures to get access to the rear chassis and remove the carrier interface assembly, to sanitize a nonfunctional
instrument before returning the instrument to Tektronix for repair. Refer to your company's internal policies regarding
handling or disposal of the carrier interface assembly. A new carrier interface assembly is installed and the instrument is
repaired and adjusted as necessary.

b.
Separate the handle from the hubs.
c.
Set the handle and the two plastic hub parts aside.
2.
Lay the instrument on its front on a soft antistatic foam pad or similar, to protect the buttons and knobs from damage
while disassembling the instrument.
3.

6.
Separate the rear chassis from the front chassis:
a.
For 5 Series instruments: use needle nose pliers to carefully remove the aluminum tape along the bottom edge of
the chassis. Discard or recycle the removed aluminum tape pieces.
WARNING.
CAUTION.
Do not use fingers to remove the aluminum tape. The tape is sharp and can cause injury.
Be careful when removing tape from across cables to prevent damage. Pull the tape off parallel to
(across) the chassis surface; do not pull the tape off by pulling straight out from the cable. Hold down the exposed
cable when removing the rest of the tape.
b.
Use a Torx T-10 screwdriver to remove the 18 screws (5 Series instruments) or 19 screws (6 Series instruments)
securing the rear chassis to the front chassis. There are five screws each along the top and bottom, and four
screws on each side.
c.
Insert a large flat blade screwdriver no more than 1/4 inch into the rectangular slot on the corner of the rear chassis
(see following image). Rotate the screwdriver to lift the corner of the rear chassis from the front chassis. Repeat
on each corner. There may be a little resistance from the front right corner of the bottom edge, where the rear
chassis interconnects to the front chassis.
