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.
