Preface
If you have data security concerns, this document helps you to sanitize or remove
memory devices from the DPO2000 and MSO2000 Series Digital Phosphor and
Mixed Signal Oscilloscopes.
The DPO2000 and MSO2000 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.
Products The following Tektronix products are covered by this document:
DPO2024
DPO2014
DPO2012
MSO2024
MSO2014
MSO2012

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.
