Overview
In many cases, it is imperative that the R&S NGM/NGL Power Supplies are used in a
secured environment. Generally, these highly secured environments do not allow any
test equipment to leave the area unless it can be proven that no user information
leaves with the test equipment. Security concerns can arise when devices need to
leave a secured area e.g. to be calibrated or serviced. This document describes the
types of memory and their usage in the R&S NGM/NGL series. It provides a statement
regarding the volatility of all memory types and specifies the steps required to
declassify an instrument through memory clearing or sanitization procedures. These
sanitization procedures are designed for customers who need to meet the
requirements specified by the US Defense Security Service (DSS).

Security Terms and Definitions
Clearing - The term "clearing" is 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 so that the data can no longer be retrieved
using the standard interfaces on the instrument. Therefore, clearing is typically used
when the instrument is to remain in an environment with an acceptable level of
protection.
Sanitization - The term "sanitization" is defined in Section 8-301b of DoD 5220.22-M,
"National Industrial Security Program Operating Manual (NISPOM)". 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 for service of calibration. The memory sanitization procedures described in
this document 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 14.1.16 of the ISFO "Manual for the
Certification and Accreditation of Classified Systems under the NISPOM".
Instrument declassification - The term "instrument declassification" refers to
procedures that must be undertaken before an instrument can be removed from a
secure environment, for example when the instrument is returned for calibration.
Declassification procedures include memory sanitization or memory removal, or both.
