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

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.
