Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from the TLA5000B Series Logic 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.
Products The following Tektronix products are covered by this document:
All TLA5000B Series Logic Analyzers
Related Documents TLA5000 Series Tektronix Logic Analyzer Service Manual, Tektronix part number
071-1305-00.
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.
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 memory device power
is removed.
N/A. Not applicable (is not necessary for this product or products).
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 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.

Drive, andCD-RW
Capability
The following instructions give a method to disable the built-in USB and CD-RW
capability. Using the BIOS disables the devices for DOS programs, while the
Windows Device Manager disables the devices for Windows programs. These
procedures disable both USB and the CD-RW to prevent their use.
