Document Purpose
This document describes instrument memory types and security features. It provides a statement regarding
the volatility of all memory types, and specifies the steps required to declassify an instrument through
memory clearing, sanitization, or removal.
For additional information, go to:
http://www.agilent.com/find/security
IMPORTANT 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.

Definitions
Term Definition
Clearing As defined in Section 8-301a of DoD 5220.22-M, “National Industrial Security
Program Operating Manual (NISPOM)”, clearing is the process of eradicating the
data on media before reusing the media in an environment that provides an
acceptable level of protection for the data that was on the media before clearing.
Hence, clearing is typically used when the instrument is to remain in an environment
with an acceptable level of protection.
Instrument
Declassification
Sanitization As defined in Section 8-301b of DoD 5220.22-M, “National Industrial Security
Secure Erase Secure Erase is a term that is used to refer to either the clearing or sanitization
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, “National Industrial Security Program
Operating Manual (NISPOM)”, Chapter 8.
Program Operating Manual (NISPOM)”, sanitization is the process of removing the
data from media before reusing the media in an environment that does not provide an
acceptable level of protection for the data that was in the media before sanitizing.
Hence, 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.
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” in
Section 5.2.5.5.5 of the ISFO Process Manual for the Certification and Accreditation
of Classified Systems under the NISPOM.

Erase All
Erase All
This function removes all user files, user flatness calibrations, user I/Q calibrations, and resets all table
editors with original factory values, ensuring that user data and configurations are not accessible or
viewable. The instrument appears as if it is in its original factory state, however, the memory is not sanitized.
This action is relatively quick, typically taking less than one minute (the exact time depends on the number of
files).
