Contacting Agilent Sales and Service Offices
Assistance with test and measurements needs, and information on finding a local Agilent office, is
available on the Internet at http://www.agilent.com/find/assist. If you do not have access to the
Internet, please contact your field engineer.
Note: In any correspondence or telephone conversation, refer to the instrument by its model
number and full serial number. With this information, the Agilent representative can determine
whether your unit is still within its warranty period.

This document describes instrument security features and the steps to declassify an instrument
through memory clearing, sanitization or removal. For additional information, go to:
http://www.agilent.com/find/security
Note: Be sure that all information stored by the user in the instrument that needs to be saved is
properly backed up before attempting to clear any of the instrument memory. Agilent Technologies
cannot be held responsible for any lost files or data resulting from the clearing of memory.
Be sure to read this document entirely before proceeding with any file deletion or memory clearing.

Terms and Definitions
Clearing – As defined in Section 8-301a of DoD 5220.22-M, Clearing is the process of eradicating
the data on media before reusing the media so that the data can no longer be retrieved using the
standard interfaces on the instrument. Clearing is typically used when the instrument is to remain
in an environment with an acceptable level of protection.
Sanitization – As defined in Section 8-301b of DoD 5220.22-M, Sanitization is the process of
removing or eradicating stored data so that the data cannot be recovered using any known
technology. Instrument sanitization is typically required when an instrument is moved from a
secure to a non-secure environment, such as when it is returned to the factory for calibration. (The
instrument is declassified.) Agilent memory sanitization procedures are designed for customers
who need to meet the requirements specified by the US Defense Security Service (DSS). These
requirements are specified in the “Clearing and Sanitization Matrix” issued by the Cognizant
Security Agency (CSA) and contained in Appendix O of the ODAA Process Guide.
Secure Erase – Secure Erase is a term that is used to refer to either the clearing or sanitization
features of Agilent instruments.
Instrument Declassification – A term that refers to procedures that must be undertaken before an
instrument can be removed from a secure environment, such as is the case when the instrument is
returned for calibration. Declassification procedures include memory sanitization or memory
removal, or both. Agilent declassification procedures are designed to meet the requirements
specified in DoD 5220.22-M, chapter 8.
