power is present.
Do not operate with suspected failures. If you suspect that there is damage to this
product, have it inspected by qualified service personnel.
Disable the product if it is damaged. Do not use the product if it is damaged or
operates incorrectly. If in doubt about safety of the product, turn it off and
disconnect the power cord. Clearly mark the product to prevent its further
operation.
Before use, inspect voltage probes, test leads, and accessories for mechanical
damage and replace when damaged. Do not use probes or test leads if they are
damaged, if there is exposed metal, or if a wear indicator shows.
Examine the exterior of the product before you use it. Look for cracks or missing
pieces.
Use only specified replacement parts.
Use proper fuse. Use only the fuse type and rating specified for this product.
Wear eye protection. Wear eye protection if exposure to high-intensity rays or
laser radiation exists.
Do not operate in wet/damp conditions. Be aware that condensation may occur if a
unit is moved from a cold to a warm environment.
Do not operate in an explosive atmosphere.

Preface
Reference
Products
This document helps customers with data security concerns to sanitize or remove
memory devices from the Tektronix BERTSCope BSX Series Bit Error Rate
Analyzers.
These products have data storage (memory) devices and data output devices.
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.
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
The following Tektronix products are covered by this document:

BERTScope BSX Series Declassification and Security Instruction vii
Preface
Terms used in this document
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.
■
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 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. 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.

Preface
Device terms
The following terms are used with the memory devices in this document:
■
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.

Follow the procedures in this section to disassemble the instrument to remove the
hard disk drive and to access the single-board computer.
You will need a screwdriver or screwdriver handle with the following tips: P1,
P2, and T15 to disassemble and reassemble the instrument.
WARNING. To avoid electric shock, always power off the instrument and
disconnect the power cord before cleaning or servicing the instrument.
CAUTION. Many components within the chassis are susceptible to static discharge
damage. Service the chassis only in a static-free environment.
Observe standard handling precautions for static-sensitive devices while
servicing the chassis.
Always wear a grounded wrist strap, or equivalent, while servicing the chassis.

Product disassembly procedures
Disassemble the instrument
1. Disconnect the power cord from the instrument and set the instrument on a
static-free, soft surface.
2. Refer to the following figure and remove the six screws from the rear of the
chassis, one screw from each corner and two screws in the center of the rear
panel.

Product disassembly procedures
Reassemble the instrument
CAUTION. The circuit boards and cables can be damaged if you incorrectly
install the cover/enclosure. Make sure that you do not damage any circuit boards
or cables when you slide the chassis into the instrument enclosure.
Make sure that you have correctly installed the hard disk drive bracket before
continuing the following steps:
1. Carefully slide the chassis into the cover shell making sure that none of the
cables get pinched outside the shell. Verify that the EMI gasketing is seated
on the front edges of the shell.
CAUTION. To avoid damaging the power cord connector, center the power
connector in the hole as you tighten the screws.
2. Attach the chassis to the cover shell using the six screws that you removed
earlier. Do not tighten the screws until all of them have started.
a. Install one of the center screws while moving the chassis as needed to
align the screw holes; install the second center screw.
b. Attach the four outside screws moving the chassis as needed to align the
screws.
