Clear and sanitize procedures
This section helps customers with data security concerns to sanitize or remove memory devices from
the Series 2200 instrument.
These products have data storage (memory) devices and a data output device (USB port). These
instructions tell how to clear or sanitize the memory devices and disable the data output device. The
instructions also tell how to declassify an instrument that is not functioning.
Terms
The following terms may be used in this topic.
•
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.
•
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.
