Preface

This document helps customers with data security concerns to sanitize or remove

memory devices from the AWG7000 Series Arbitrary Waveform Generators.

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.

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 device. Any of several devices that can be 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.

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. 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-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.

Disabling USB and CD-RW

Capability

The following instructions give a method to disable the built-in USB and CD-RW

capability. Using the BIOS disables the devices for DOS programs, while the

Windows Device Manager disables the devices for Windows programs. These

procedures disable both USB and the CD-RW to prevent their use.

To Disable USB and CD-RW for Windows Using the Windows Device Manager.

1. Connect a PS2 mouse and a PS2 keyboard to the instrument before powering

on (because USB will be disabled).

2. Log on to the instrument as an administrator.

3. From the Windows Start menu, select Control Panel, and then select System.

4. Select the Hardware tab.

5. Click Device Manager.

6. Expand the Universal Serial Bus controllers entry by clicking the + next to it.

7. Double-click the first USB Root Hub entry.

8. Select the Power tab.

9. If the Device Description is anything other than Generic USB Hub (4 ports),

click the General tab, and select Do not use this device (disable) in the Device

Usage drop-down list.

10. Click OK.

11. Repeat steps 7 through 9 for each USB Root Hub shown in the Device Manager

window.

NOTE. If you disable the USB, CD-RW, and LAN in the following procedures, you

cannot write new firmware to the hard drive. To do so, you will need to enable one

of these items.

NOTE. It is critical to leave the USB Root Hub operating, otherwise, the front panel

will not function. If the front panel does not function, the AWG application will not

run.

12. Expand DVD/CD-ROM drives in the Device Manager window.

13. Right-click TEAC DW-224E-C, and select Disable.

14. Reboot the instrument to make the changes effective.

15. We suggest that you password-protect the Windows Administrator account

and set up Guest accounts for end users so that these changes cannot be easily

reversed.

To disable LAN Ethernet

Connectivity Using the

BIOS

1. Press F2 during instrument Boot Up to go to the BIOS configuration menu.

2. Go to Advanced > Peripheral Configuration.

3. Set Onboard LAN to Disabled.

4. Press Esc one time to return to the main BIOS configuration menu.

5. Press F10, and select OK to save changes and exit. The LAN system will be

disabled and no longer allow data traffic in or out.

To Disable TekLink Using

the Windows Device

Manager

1. Connect a PS2 mouse and a PS2 keyboard to the instrument before powering

on (because USB will be disabled).

2. Log on to the instrument as an administrator.

3. From the Windows Start menu, select Control Panel, and then select System.

4. Select the Hardware tab.

5. Click Device Manager.

6. Expand the device category Network Adapters.

7. Double click on the Intel(R) PRO/100 M Network Connection. This will be the

Network Adapter located on the interface board in PCI slot 2.

8. Click the General tab, and select Do not use this device (disable) in the Device

Usage drop-down list.

To Disable GPIB Using the

Windows Device Manager

1. Connect a PS2 mouse and a PS2 keyboard to the instrument before powering

on (because USB will be disabled).

2. Log on to the instrument as an administrator.

3. From the Windows Start menu, select Control Panel, and then select System.

4. Select the Hardware tab.

5. Click Device Manager.

6. Expand the device category National Instruments GPIB Interfaces.

7. Right click on PCI-GPIB.

8. Select Disable from the list.

Removable Hard Drive To Remove the Hard Drive. To remove the hard disk drive assembly, see the

instrument user online help (AWG Reference > Removable Hard Disk). You can

also refer to the AWG7000 Series HDD Installation Instructions, Tektronix part

number 075-0922-XX.

All user-storable data is stored on the rear-panel removable hard drive. There are

DOD-approved scrubbing software packages available for the hard drive.

Tektronix has no recommendations regarding the available packages.

After the hard drive has been scrubbed, the operating system and instrument

software can be reinstalled using the Operating System Restore DVD and Product

Software CD that ship with the instrument.

Scrubbing the hard drive will not affect calibration of the instrument, since the

factory calibration constants are stored on the MIO board, entirely separate from

any waveform data or setup files. You can completely erase or remove any secure

data without affecting the calibration of the instrument. You can also calibrate the

instrument in a nonsecure site, and then use the instrument in a secure area without

recalibration.
