Preface
If you have data security concerns, this document helps you to sanitize or
remove memory devices from the Tektronix MDO4000C Series Mixed Domain
Oscilloscopes and Modules.
The MDO4000C Series products have data storage (memory) devices and data
output devices (USB ports). These instructions tell you how to clear or sanitize
the memory devices, and also tell you how to declassify an instrument that is not
functioning.
Instrument code and calibration settings reside in nonvolatile flash memory.
Instrument setups and reference waveforms may also be stored in flashmemoryor
on USB drives connected to the instrument.
If you have any questions, contact the Tektronix Technical Support Center at
www.tektronix.com/support.
Reference The procedures in this document are written to meet the requirements specified in:

www.tektronix.com/download.
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.
Demo setups. These setups come loaded in the instrument, and cannot be
modified by the customer.
Erase. This is equivalent to clear.
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.
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 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 will need to remove the power source from the instrument.
Protected user data area. Contains data that is protected by a password.
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
nonsecured area.
Scrub. The user is able to directly retrieve the memory device contents.
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.

Clear and Sanitize Procedures
Sanitizing an Application Module
To sanitize an application module, follow this procedure to return the module to
the default state.
NOTE. This procedure is for an application module that has its license transferred
to an oscilloscope. If the module license is not installed in an oscilloscope, the
module is already in the default state.
1. With the application module installed in an oscilloscope that contains the
module’s license, push the front-panel oscilloscope Utility button.
2. Use the Multipurpose a knob to select Config.
3. Select Application Module Licenses.
4. Under the Transfer Licenses menu, select to transfer the license to the desired
application module. For example, to sanitize the DPO4AERO module, select:
Transfer DPO4AERO License to Module.
NOTE. If the module cannot be selected in the menu, this indicates that the module
license is not contained in that oscilloscope. Install the module in an oscilloscope
that does contain the module license and then perform step 4.
5. The module is returned to the default state.

Built-In Security Features
You can use the TekSecure function to erase setup and reference waveform data
stored in internal flash memory.
The MDO4000C Series models have four USB host ports (two on the front and
two on the rear panel) and one USB device port on the rear panel. Any USB
devices can be removed and stored or destroyed.
What TekSecure Does NOTE. TekSecure does not erase or change factory calibration constants, Ethernet
settings, Demo setups, or protected user data. To overwrite protected user data,
use the provided procedure. (See page 10, To Overwrite Protected User Data.)
The TekSecure function does the following:
Erases the flash sector containing the reference waveforms and saved setups
(except Demo setups), setting all bytes to the value 0xff.
Replaces all waveforms in all reference waveform memories with the null
sample value of 0x8000.
Replaces the current front-panel setup and all stored setups (except Demo
setups) with the default setup values
Calculates the checksums of all reference waveform memory and setup
memory locations to verify successful completion of waveform and setup
erasure.
Displays a dialog box indicating whether the secure erase was successful
or unsuccessful.
To Use TekSecure 1. Push the front-panel Utility button.
2. Push the Utility Page lower-bezel button and use the Multipurpose a knob
to select Config.
3. Push the TekSecure Erase Memory lower-bezel button.
