Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from TLA6000 series logic analyzers.
These products have data storage (memory) devices and data output devices.
These instructions tell how to do the following:
Clear or sanitize the memory devices
Clear or sanitize an instrument that is not functioning

The following Tektronix products are covered by this document:
TLA6202 and all options
TLA6203 and all options
TLA6204 and all options
Refer to the following service-related documents available on the Tektronix Web
site at www.tektronix.com/manuals or to the TLA Documentation CD that is
available with your product:

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.
Power off. The 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 must
remove the power source from the instrument.

capability. Using the Windows Device Manager disables the devices for Windows
programs. This procedure disables both USB and the CD-RW to prevent their use.
NOTE. If you disable the USB, CD-RW, and LAN in the following procedures,
you cannot write new firmware to the hard drive. To do so, you must e nable one

To Remove the Hard Disk Drive. To remove the hard disk drive assembly, refer to
the TLA6000 Series Logic Analyzer Installation Manual.
All user-storable data is stored on the hard disk drive. Scrub the hard disk drive in
a manner that meets local and a ny other security requirements that you have.
NOTE. Before scrubbing the hard disk drive, make certain that you created OS
Restore CD-ROMs. For more information, see Creating Operating System
Restore CD-ROMs in the TLA6000 Series Logic Analyzer Installation Manual.
After the hard disk drive has been scrubbed, the operating system and TLA
application software can be reinstalled.
Scrubbing the hard disk drive will not affect calibration of the instrument. You
can completely erase or remove any secure data without a ffecting the calibration
of the instrument.
