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 unintention-
ally 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 FPH.

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; typi-
cally 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 is to keep physical media holding sensitive information within the classi-
fied area, see [1], paragraph 4.4.
Volatile memory
"Memory components that do not retain data after removal of all electrical power sour-
ces, 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 con-
tents when power is removed from the instrument.
If the instrument is battery operated, e.g. handhelds, it retains data in the volatile mem-
ory 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 acces-
sible internal memory types, e.g. EEPROM, Flash, etc.

Media
Media are types of non-volatile memory components. Media are user-accessible and
retain data when you turn off power.
In the context of this document, 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 FPH Spectrum Analyzer contains various memory components. See the sub-
sequent 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 mem-
ory sizes may not represent the current, but the minimal configuration.
4.1 Volatile Memory
Volatile memory modules are considered as non-accessible internal memory devices,
as described in Security Terms and Definitions > Volatile Memory. It requires power to
retain data and when the power is turned off, all data is erased.

require power to maintain the stored data.

Instrument Sanitization Procedure

10Instrument Security Procedures 1178.8994.02 ─ 05
5 Instrument Sanitization Procedure
Firmware greater or equal 1.60 is required for the instrument declassification.
5.1 Volatile Memory
Removing power
1. Turn off the R&S FPH.
2. Remove the battery.
Leave the instrument powered off at least for 10 minutes to make sure that all vola-
tile memory modules lose their contents.
5.2 Non-volatile Memory
The Flash does not lose its contents when power is removed. It can contain user data.
Sanitizing the non-volatile memory
The Flash is cleared by executing the sanitizing procedure provided on the instrument.
The sanitizing procedure complies to the definition of NIST, see "Terms defined in
Guidelines for Media Sanitization" on page 6.
1. NOTICE! Risk of loosing data. The sanitization procedure clears all user data and
resets the instrument.
Back up all data you want to keep.
2. Remove all media:
a) Disconnect USB mass memory.
b) Remove microSD card.
For information on how to proceed, see the corresponding instructions in the
user manual of the R&S FPH.
3. Keep the media memory devices under organizational control.
4. NOTICE! Risk of instrument damage when interrupting the sanitizing procedure.
Do not turn off or disconnect the R&S FPH from the mains while the sanitizing pro-
cedure is running.
Wait until the instrument confirms the completed sanitizing.
To activate the sanitizing procedure, press and hold the [PRESET] and [F5] keys
while switching on the instrument.
