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.

Memory Sanitization Procedures

Memory Sanitization Procedures

NOTE

IMPORTANT! N755xA ECal models require ’ECal Module Security Wipe for the PNA’ revision 3.50 or later.
Memory Clearing, Sanitization and/or Removal Procedures
This section explains how to clear, sanitize, and remove memory from your instrument for all memory that can be written to during normal operation.
For Memory Clearing and Sanitization:
NOTE
IMPORTANT! The memory clearing and sanitization process only removes any user data stored in the ECal memory (i.e., it does NOT remove the factory calibration).
To clear or sanitize the ECal memory, two ECal Data Wipe Utility has been developed which will destroy all user data per US DoD 5220.22M. To download the latest version, click on the URL below. http://na.support.Keysight.com/pna/apps/applications.htm
Select ECal Module Security Wipe Stand-Alone for PC and run this program on any windows PC or ENA with firmware revision 9.2 or later. If the ECal is used with an PNA, then select the ’ECal Module Security Wipe for the PNA’ which require the PNA to have firmware revision A.03.50 or later. Follow the instructions on the ECalWipeReadMe document that is contained within the utility.
For Memory Removal:
This memory can NOT be removed without damaging the ECal.
Learn more, refer to “Procedure for Declassifying a Faulty Instrument” on page 9.

Procedure for Declassifying a Faulty Instrument

Definitions:
Clearing – 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 – 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.) 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 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 8301.
Security erase – A term that is used to refer to either the clearing or sanitization features of Keysight 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. Keysight declassification procedures are designed to meet the requirements specified by the DSS NISPOM security document (DoD 5220.22M chapter 8).
