Preface
This document helps customers with data security concerns to clear or remove
memory devices from the DSA8200 and modules.
The DSA8200 mainframes contain an open architecture PC with removable hard
drive. All user storable data, such as waveforms, instrument settings, and screen
shots, are stored on the removable hard drive. The hard drive is located on the
rear panel. Remove the hard drive for storage or destruction. Additional hard
drives can be purchased from Tektronix.
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.
Products The following Tektronix products are covered by this document:

Terms The following terms may be used in this document:
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 pressarear-panelOFFswitchorremovethe
power source from the instrument.

Remove. This is aphysicalmeanstoclearthedatabyremovingthememory
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.
