Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from TLA7SA08 and TLA7SA16 Serial Analyzer Modules.
These products have data storage (memory) devices and data output devices (USB
ports). These instructions tell how to do the following:
Clear or sanitize the memory devices
Clear or sanitize an instrument that is not functioning

Terms
The following Tektronix products are covered by this document:
TLA7SA08
TLA7SA16
The TLA7SA08 and TLA7SA16 Serial Analyzer Modules do not have a separate
service manual. Refer to the TLA7S08 and TLA7S16 Serial Analyzer Modules
Service Manual (Tektronix part number, 071-2188-XX) for the basic remove
and replace instructions. This manual is available on the Tektronix Web site
at www.tektronix.com/manuals. For other service needs, contact your local
Tektronix representative.
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.
Media storage/data export. Various devices that are 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.
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-modifiable. The memory device can be written to by the user during normal
instrument operation, using the instrument’s user interface or remote control.

Security Procedure
User data is not stored in nonvolatile memory. To secure nonvolatile memory,
proceed as follows:
1. Remove the LPU board and Acquisition board from the module. Refer to
the Tektronix Logic Analyzer Solutions for PCI Express 3.0 Instruction
Manual (Tektronix part number, 077-0400-XX) on the Tektronix Web site at
www.tektronix.com/manuals.
2. Since there is no way for you to erase nonvolatile memory, either store these
rcuit boards in a secure area or destroy them.
