Preface

This document helps customers with data security concerns to sanitize or remove memory devices from the FCA3000,

FCA3100, and MCA3000 Series instruments.

These products have data storage (memory) devices and data export devices (USB port and GPIB connector). These

instructions describe 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:

FCA3000, FCA3003, and FCA3020

FCA3100, FCA3103, and FCA3120

Preface

Terms

This document may use the following terms:

Clear. This eradicates 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.

Media. Storage/data export device. A device that stores or exports data from the instrument, such as a USB ﬂash

drive or USB port.

Sanitize. This removes the data from media/memory so that the data cannot be recovered using any known technology.

This is typically used when the device is moved (temporarily or permanently) from a secured area to a nonsecured area.

Scrub. This is equivalent to sanitize.

User-Accessible. The user can directly retrieve the memory device contents.

User-Modiﬁable. The memory device can be written to by the user during normal instrument operation, using the

instrument user 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.

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

data, putting the instrument in Standby mode does not qualify as powering off. For these products, you must either

push a rear-panel OFF switch or remove the power source from the instrument.

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.

Clear and Sanitize Procedures

Memory Devices

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

Terminology The tables in this section use the following terms:

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

information 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

changed by the user.

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 or 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 modiﬁes the data and that

the user cannot modify the data.

1The Total Reset function writes 0xFF to all ﬂash sectors that hold stored user data (saved measurement data).

The Total Reset function also resets ﬂash sectors that hold current instrument settings (including power-on settings, but excluding instrument conﬁguration settings) to their default (factory reset) settings. However, due to

internal sector organization of the ﬂash memory, and depending on the size of the setting data, settings may be stored in two ﬂash sectors. Parts of previous setting data might exist in a ﬂash sector with the current setting

data. The Total Reset function sets the current settings storage memory to the default settings, but previous conﬁguration settings data can persist in the noncurrent-settings locations within memory sectors.
