Preface
If you have data security concerns, this document helps you to sanitize or remove
memory devices from the Tektronix 4000 Series Digital Phosphor Oscilloscopes.
The 4000 series products have data storage (memory) devices and data output
devices (CompactFlash card, and 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 CompactFlash and 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. Thisisaphysicalmeanstoclearthedatabyremovingthememory
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 4000 series models have three USB host ports (one on the front and two on
the rear panel) and one CompactFlash port on the front panel. Any USB flash
devices or CompactFlash cards 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 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 and 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.

write down all setting values before clearing them.
1. Remove the network cable from the LAN port on the rear of the instrument.
2. Push the front-panel Utility button.
3. Push the Utility Page lower-bezel button and use the Multipurpose a knob
to select I/O.
4. Push the Ethernet Network Settings lower-bezel button.
5. Push the Change Instrument Settings side-bezel button.
6. Push the ↑or ↓arrow side-bezel button to position the cursor on the User
Password information.
7. Push the Clear lower-bezel button.
8. Push the ↓arrow side-bezel button to position the cursor on the Instrument
IP Address information.
9. Push the Clear lower-bezel button.
