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 sanitization. For additional information, please 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
Definitions:
Clearing – 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 – 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 outlined in the “Clearing
and Sanitization Matrix” issued by the Cognizant Security Agency (CSA) and referenced in National Industrial
Security Program Operating Manual (NISPOM) DoD 5220.22M ISL 01L-1 section 8-301.
Security erase – Security 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 will include memory sanitization and or memory removal. Agilent declassification
procedures are designed to meet the requirements specified by the DSS NISPOM security document (DoD
5220.22M chapter 8)
