Preface

This document h elps customers with data security concerns to sanitize or remove memory devices from the PPG3000 or PPG3200 Series Programmable Pattern Generators or the PED3200 Series Programmable Error Detectors.

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 t he data output devices. The instructions also tell how to declassify a non functioning instrument.

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 m emory device contents.

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

interface or remote control.

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.

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 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.

The instrument should now have the factory default parameters loaded and all user instrument setup ﬁles and all user pattern data ﬁles should be deleted.

Power off the instrument.

No recovery from a clear is needed as the nonvolatile clear procedure does not erase or change factory calibration constants and the instrument ﬁrmware is not impacted. There is no standard sanitization procedure as it requires partial disassembly of the instrument that is only permitted by factory authorized personnel.

covers unless you are qualiﬁed to do so. For additional information, contact your local Tektronix service representative.

If your instrument is not functioning and you need to clear or sanitize it, the SD card should be removed and the instrument should be returned to Tektronix Inc. To remove the SD card, the chassis covers must be removed and the SD card must be removed from the processor board. Please contact your local Tektronix service representative for more SD card removal details.

The SD card is the only part of the instrument that will retain user data (such as pattern data or instrument setups) after the instrument has been turned off.

Replacement of any missing hardware will be charged according to the rate at the time of replacement.

Removing instrument covers to access internal components invalidates your warranty. Do not remove instrument
