Preface

This document helps customers with data security concerns to sanitize or remove memory devices from the Tektronix BERTScope BSA Series Bit Error Rate Analyzers.

These products have data storage (memory) devices and data output devices (USB ports). These instructions tell how to clear or sanitize the memory devices and disable the data output devices. The instructions also tell how to declassify an instrument that is not functioning.

Terms

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

Preface

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.

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.

Nonvolatile memory.

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 will need to 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.

User accessible.

User-modiﬁable.

This is equivalent to sanitize.

User is able to directly retrieve the memory device contents.

The u ser can write to the memory device during normal instrument operation, using the instrument

interface or remote control.

User-modiﬁable.

The u ser can write to the memory device during normal instrument operation, using the instrument

Volatile memory.

Data is lost when the instrument is powered off.

Memory devices

The following tables list the volatile and nonvolatile memory devices. 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 changed by the user.

Both – Describes the type o f 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 d ata.
