Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from the MTS4000 MPEG Test Systems.
These products have data storage (memory) devices and data output devices (USB
ports). These instructions tell how to clear or sanitize the memory devices and
disable the data output devices. The instructions also tell how to declassify an
instrument that is not functioning.

The following terms may be used in this document:
Clear. This removes data o n 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. This refers to 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

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. Th
