Preface

This document helps customers with data security concerns to sanitize or remove memory devices from the RSA6100A

Series Real-Time Spectrum Analyzers.

These products have data storage (memory) devices and data output devices (USB ports). These instructions explain

how to clear or sanitize the memory devices and disable the data output devices. The instructions also describe how to

declassify an instrument that is not functioning.

Reference The procedures in this document are written to meet the requirements speciﬁed in:

NISPOM, DoD 5220.22–M, Chapter 8

ISFO Process Manual for Certiﬁcation & Accreditation of Classiﬁed Systems under NISPOM

Products The following Tektronix products are covered by this document:

RSA6106A

RSA6114A

RSA6120A

Terms The following terms may be used in this document:

Clear. This removes data on media/memory before reusing it in a secured area. All reusable memory is cleared to

deny access to previously stored information by standard means of access.

Erase. This is equivalent to clear.

Instrument Declassiﬁcation. A term that refers to procedures that must be undertaken before an instrument can be

removed from a secure environment. Declassiﬁcation procedures include memory sanitization and memory removal,

and sometimes both.

RSA6100A Series Declassiﬁcation and Security Instructions iii

Preface

Media storage/data export device. Any of several devices that can be used to store or export data from the

instrument, such as a USB port.

Power off. Some instruments have a “Standby” mode, in which power is still supplied to the instrument. For the

purpose of clearing data, putting the instrument in Standby mode does not qualify as powering off. For these products,

you must either press a rear-panel OFF switch or remove the power source from the instrument.

Remove. This is a physical means to clear the data by removing the memory device from the instrument. Instructions

are available in the product Service Manual.

Sanitize. This eradicates the data from media/memory so that the data cannot be recovered by other means or

technology. This is typically used when the device will be moved (temporarily or permanently) from a secured

area to a non-secured area.

Scrub. This is equivalent to sanitize.

User Accessible. User is able to directly retrieve the memory device contents.

User-modiﬁable. The user can write to the memory device during normal instrument operation, using the instrument

interface or remote control.

Volatile memory. Data is lost when the instrument is powered off.

Nonvolatile memory. Data is retained when the instrument is powered off.

Clear and Sanitize Procedures

Memory Devices

The following tables list the volatile and nonvolatile memory devices in the standard instrument and listed options.

Detailed procedures to clear or sanitize these devices, if any, are shown following each table.

Terminology The following terms are used in the tables in this section:

User data – Describes the type of information stored in the device. Refers to waveforms or other measurement data

representing signals connected to the instrument by users.

User settings – Describes the type of information stored in the device. Refers to instrument settings that can be

changedbytheuser.

Both – Describes the type of information stored in the device. It means that both user data and user settings are

stored in the device.

None – Describes the type of information stored in the device. It means that neither user data nor user settings

are stored in the device.

Directly – Describes how data is modiﬁed. It means that the user can modify the data.

Indirectly – Describes how data is modiﬁed. It means that the instrument system resources modify the data and that

the user cannot modify the data.

RSA6100A Series Declassiﬁcation and Security Instructions 3

Clear and Sanitize Procedures

Clearing Hard Disk Drives If your organization’s security protocols allow the use of software to purge or sanitize hard drives, you can use commercial

software to erase free space on the hard drive before sending the instrument out for upgrades or repair. Follow the

instructions that come with the software to ensure that the erasure of sensitive data from the hard drive complies with your

organization’s security protocols.

Sequence for clearing secure data from a hard drive:

1. Delete all stored signals and instrument settings ﬁles (all ﬁles stored with a tiq,csv,orSetup extension).

2. Acquire several full memory-length acquisitions of noise (no signal attached to the input).

Without Option 02, acquire a full-length acquisition 16 times.

With Option 02, acquire a full-length acquisition 4 times.

3. Close the RSA6100A applications and erase the free space on the hard disk using commercial software.

Fixed Hard Drive Removal

Procedure

The following procedure applies to instruments that have Option 07 (DVD-RW drive) installed. If your instrument has

a DVD drive, it has a ﬁxed hard drive. This procedure is an overview of the removal process. For detailed removal

and replacement procedures, see the RSA6100A Series Real-Time Spectrum Analyzers Service Manual, Tektronix part

number 077-0250-XX.

WARNING. Only qualiﬁed service personnel should perform this procedure. Read the Service Safety Summary and the

General Safety Summary in the RSA6100A Series Real-Time Spectrum Analyzers Service Manual (Tektronix part number

077-0250-XX) before performing this procedure.

WARNING. Before performing this procedure, disconnect the power cord from the line voltage source. Failure to do so

could cause serious injury or death.

CAUTION. To avoid damaging the hard drive, perform the following procedure in a static-safe environment with proper

electro-static discharge controls in place.
