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
Products The following Tektronix products are covered by this document:
TLA6202 and all options
TLA6203 and all options
TLA6204 and all options
Related Documents 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:
TLA6000 Series Logic Analyzer Installation Manual
TLA7000 Series Mainframe Technical Reference Manual
TLA7ACx Logic Analyzer Module Service Manual
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. 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.
Remove. Thisisaphysicalmeanstoclearthedatabyremovingthememory

manual.

Preface
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.
Volatile memory. Data is lost when the instrument is powered off.

Disabling USB and CD-RW
Capability
The following instructions give a method to disable the built-in USB and CD-RW
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 enable one
of these items.
TLA6000 Declassification and Security Instructions 3

Clear and Sanitize Procedures
To disable USB and CD-RW for Windows using the Windows Device Manager
complete the following steps:
1. Connect a PS2 mouse and a PS2 keyboard to the instrument before powering
on (because USB will be disabled).
2. Logontotheinstrument as an administrator.
3. From the Windows Start menu, go to Control Panel >System.
4. Select the Hardware tab.
5. Click Device Manager.
6. Expand the Universal Serial Bus controllers entry by clicking the + next to it.
7. Double-click the first USB Root Hub entry.
8. Select the Power tab.
9. If the Device Description is anything other than Generic USB Hub (4 ports),
click the General tab, and select Do not use this device (disable) in the Device
Usage drop-down list.
NOTE. It is critical to leave the USB Root Hub operating, otherwise, the front
panel will not function. If the front panel does not function, the TLA application
will not run.
10. Click OK.
11. Repeat steps 7 through 9 for each USB Root Hub shown in the Device
Manager window.
12. Expand DVD/CD-ROM drives in the Device Manager window.
13. Right-click the drive, and select Disable.
14. Restart the instrument to make the changes effective.
15. Tektronix suggests that you password-protect the Windows Administrator
account and set up Guest accounts for end users so that these changes cannot
be easily reversed.
To Disable LAN Ethernet
Connectivity Using the
BIOS
1. Press Delete during instrument Boot Up to go to the BIOS configuration menu.
2. Go to Advanced >Peripheral Configuration.
3. Set Onboard LAN to Disabled.
