Preface
If you have data security concerns, this document helps you to sanitize or remove
memory devices from the DPO2000/B and MSO2000/B Series Digital Phosphor
and Mixed Signal Oscilloscopes.
The DPO2000/B and MSO2000/B 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.

Preface
Terms The following termsmaybeusedinthisdocument:
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 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 either press a rear-panel OFF switch or remove the
power source from the instrument.
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.

Built-In Security Features
Built-In Security Features
When to Use TekSecure
You can use the TekSecure function to erase setup and reference waveform data
stored in internal flash memory.
The DPO2000/B and MSO2000/B series models have a USB host port on the
front panel. Any USB flash devices can be removed, and stored or destroyed.
What TekSecure Does
The TekSecure function does the following:
Replaces all waveforms in all reference memories with null sample values
Replaces the current front-panel setup and all stored 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 indicating whether the secure erase was successful or
unsuccessful
NOTE. TekSecure does not erase or change factory calibration constants, user
protected data, or Ethernet settings.
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.
4.Push the OK Erase Setup & Ref Memory side-bezel button. Wait for the
“TekSecure operation complete” dialog box to display.
5. Push the Menu Off front-panel button to close the dialog box.
To reset the instrument
RAM:
1. Power off the instrument for at least 20 seconds.
2. Power on the instrument.
