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.keysight.com/find/security
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. Keysight
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.

Security Terms and Definitions
Term Definition
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.
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. Keysight
declassification procedures are designed to meet the requirements specified in DoD 5220.22-M,
Chapter 8.
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.
Keysight 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.
Secure Erase Secure Erase is a term that is used to refer to either the clearing or sanitization features of Keysight
instruments.

Instrument Memory
This section contains information on the types of memory available in your instrument. It explains
the size of memory, how it is used, its location, volatility, and the sanitization procedure.

Summary of Memory Declassification Procedures
This section explains how to clear, sanitize, and remove memory from you instrument for all
memory that can be written to during normal operation and for which the clearing and sanitization
procedure is more than trivial such as rebooting your instrument.
