1 Overview
Securing important information is crucial in many applications.
Generally, 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,
e.g. to be calibrated.
"Regarding sanitization, the principal concern is ensuring that data is not unintentionally released" [1].
This document provides a statement regarding the volatility of the memory types used
and specifies the steps required to sanitize an instrument.
The procedures in this document follow "NIST Special Publication 800-88: Guidelines
for Media Sanitization" [1].
In addition, recommendations are provided to safeguard information on the
R&S SMW200A.

3 Security terms and definitions
Terms defined in Guidelines for Media Sanitization
NIST Special Publication 800-88 [1]
●
Sanitization
"Media sanitization refers to a process that renders access to target data on the
media infeasible for a given level of effort."
●
Clear
"Clear applies logical techniques to sanitize data in all user-addressable storage
locations for protection against simple non-invasive data recovery techniques; typically applied through the standard Read and Write commands to the storage
device, such as by rewriting with a new value or using a menu option to reset the
device to the factory state (where rewriting is not supported)."
●
Purge
"Purge applies physical or logical techniques that render Target Data recovery
infeasible using state of the art laboratory techniques."
●
Destroy
"Destroy renders Target Data recovery infeasible using state of the art laboratory
techniques and results in the subsequent inability to use the media for storage of
data."
Control of media
Another option to secure sensitive information is to keep physical media within the
classified area, see [1], paragraph 4.4.

Statement of volatility
Volatile memory
Volatile memory
"Memory components that do not retain data after removal of all electrical power sources, and when reinserted into a similarly configured system, are considered volatile
memory components." [2]
The volatile memory in the instrument does not have battery backup. It loses its contents when power is removed from the instrument.
If the instrument is battery operated, e.g. handhelds, it retains data in the volatile memory as long as the battery is installed.
Typical examples are RAM, e.g. SDRAM.
Non-volatile memory
"Components that retain data when all power sources are discontinued are non-volatile
memory components." [2].
In the context of this document, non-volatile memory components are non-user accessible internal memory types, e.g. EEPROM, Flash, etc.
Media
Media are types of non-volatile memory components. In the context of this document,
media are user-accessible and retain data when you turn off power.
Media types are Hard Disk Drives (HDD), Solid State Drives (SSD), Memory Cards,
e.g. SD, microSD, CFast, etc., USB removable media, e.g. Pen Drives, Memory Sticks,
Thumb Drives, etc. and similar technologies.
4 Statement of volatility
The R&S SMW200A contains various memory components. See the subsequent sections for a detailed description regarding type, size, usage and location.
Notes on memory sizes
Due to the continuous development of memory components, the listed values of memory sizes may not represent the current, but the minimal configuration.
4.1 Volatile memory
Volatile memory modules refer to non-accessible internal storage devices, as described in Security terms and definitions > Volatile memory.
