Preface

This document helps customers with data security concerns to sanitize or

remove memory devices from TDS1000B and TDS2000B Series Digital Storage

Oscilloscopes.

These products have data storage (memory) devices and data output devices (USB

ports). These instructions tell how to do the following:

Clear or sanitize the memory devices

Clear or sanitize an instrument that is not functioning

Products The following Tektronix products are covered by this document:

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.

Media storage/data export. Various devices that are used to store or export data

from the instrument, such as a USB port.

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

Remove. Thisisaphysicalmeanstoclearthedatabyremovingthememory

device from the instrument. Instructions are available in the product service

manual.

TDS1000B and TDS2000B Series Declassiﬁcation and Security iii

Preface

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-modiﬁable. The memory device can be written to by the user during normal

instrument operation, using the instrument’s user interface or remote control.

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