Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from their instrument.
This series of instruments contains an open architecture PC with removable mass
storage. You can order additional removable mass storage devices to swap in and
out of the instrument as needed for security reasons.
These products have data storage (memory) devices and data export interfaces
(USB ports, Ethernet, and eSATA). These instructions describe how to clear or
sanitize the memory devices and disable the data output interfaces. The
instructions also describe how to declassify an instrument that is not functioning.
Products
The following Tektronix products are covered by this document:
■TBS2072B
■TBS2102B
■TBS2202B
■TBS2074B
■TBS2104B
■TBS2204B

Terms
The following terms may be used in this document:
■Clear: This eradicates 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. A device that is used to store or export
data from the instrument, such as a USB port/USB flash drive.
■Sanitize: This removes the data from media/memory so that the data cannot
be recovered using any known technology. This is typically used when the
device will be moved (temporarily or permanently) from a secured area to a
nonsecured area.
■Scrub: This is equivalent to sanitize.
■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.
■User Accessible: User is able to directly retrieve the memory device
contents.
■User-Modifiable: The memory device can be written to by the user during
normal instrument operation, using the instrument user interface or remote
control.
■Volatile memory: Data is lost when the instrument is powered off.
■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 must either press a rear-panel OFF switch or remove the power
source from the instrument.
■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.

Clear and sanitize procedures
If your instrument is not functioning and you need to clear or sanitize it, proceed
as follows:
Main board
Remove the Main board and return the product to Tektronix. A new main board
will be installed, and the instrument will be repaired and adjusted as necessary.
For removal instructions, refer to the TBS2000B Series Digital Storage
Oscilloscope Service Manual , part number 077-1150-XX, available on the
Tektronix Web site at www.tek.com/manuals.
After removal of the main board, refer to your company's internal policies
regarding storage or disposal of the board.
USB flash drive
Remove the USB flash drive and return the instrument to Tektronix for repair.
After removal of the USB flash drive, refer to your organization's internal
policies regarding handling or disposal of the flash drive.

Charges
Replacement of any missing hardware will be charged according to the rate at the
time of replacement.
TekSecure
TekSecure™ capability is present in TBS2000B oscilloscopes. Pressing
TekSecure erases and overwrites all of the waveform and setup memories. The
waveform memories, stored in nonvolatile memory, are overwritten with an
"empty," all zeros pattern. The setup memories, stored in nonvolatile memory,
are overwritten with the factory default front-panel setup. The current front-panel
setup is also overwritten with the default factory setup.
Using TekSecure will not affect calibration of the instrument because the
calibration constants are stored in another nonvolatile memory completely
separate from any acquisition data. This allows complete erasure/removal of any
secure data without affecting the oscilloscope calibration. It also allows the
oscilloscope to be calibrated in a non-secure site and then used in a secure area
without the need for recalibration.
Memory devices
The following tables list the volatile and nonvolatile memory devices in the
instrument.
