Thiseradicates data on media/memory before reusing it in a secured area.All reusable memory is cleared to deny access to previously storedinformation by standard means of access.Erase. Thisis equivalent to clear.Media. Storage/dataexport device. A device that is used to store or export data fromthe instrument, such as a USB port/USB flash drive.Sanitize. This removes the data from media/memory so that the data cannotbe recovered using any known technology. This is typically used whenthe device will be moved (temporarily or permanently) from a securedarea to a nonsecured area.Scrub. Thisis equivalent to sanitize.Remove. This is a physical means to clear the data by removing the memorydevice from the instrument. Instructions are available in the productservice manual.User Accessible. User is able to directly retrieve the memory device contents.User-Modifiable. The memory device can be written to by the user during normal instrumentoperation, 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 poweris still supplied to the instrument. For the purpose of clearing data,putting the instrument in Standby mode does not qualify as poweringoff. For these products, you must either press a rear-panel OFF switchor remove the power source from the instrument.Instrument Declassification. A term that refers to procedures that must be undertaken beforean instrument can be removed from a secure environment. Declassificationprocedures include memory sanitization and memory removal, and sometimesboth.not usedClear and Sanitize ProceduresMemory DevicesThe following tables list the volatile and nonvolatilememory devices in the instrument.TerminologyThe following terms are used in the tables in thissection:User data – Describes the type ofinformation stored in the device.

If your organization's security protocols allowthe use of software to purge or clear hard drives/solid state drives,you can use commercial software to erase free space on the drive beforesending the instrument out for upgrades or repair. Follow the instructionsthat come with the software to be sure that the erasure of sensitivedata from the drive complies with your organization's security protocols.On solid state drives, the drive and the operating system worktogether to reallocate sectors on the drive to even out the wear ofthe storage cells. Make sure that software you use to purge or cleara solid state drive is approved for solid state drives.Before clearing the drive to meet securityrequirements, be sure that an OS-restore disk and product softwarerestore disk are available and that you have the procedures neededto restore the OS and product software. On MSO5000/B and DPO5000/BSeries instruments, if you delete files that are required by the operatingsystem or the instrument software, you must install a new drive thathas the OS and instrument software already installed.Sequence for clearing secure data from a drive:Erase all files with the following extensions:*.png; *.bmp;*.pcx, *.tif, *.jpg –These file types can be screenshots that can contain valuable information.*.msk, *.set, *.wfm, *.csv, *.txt, *.dat– These file types can contain data exported from the instrument(setup, waveforms, measurement results).Acquire several full memory-length acquisitionsof noise (no signal attached to the input).Close the TekScope application and erasethe free space on the hard disk using commercial software.Removinga Removable Hard Drive/Solid State DriveFor detailed information on removing parts fromthe instrument, see the DPO5000/B, DPO7000/C,DPO70000/B/C/D/DX, DSA70000/B/C/D, MSO5000/B, and MSO70000/C/DX SeriesService Manual, Tektronix part number 077-0076-XX.Before doing this procedure, disconnectthe power cord from the line voltage source. Failure to do so couldcause serious injury or death.To avoid damaging the drive, perform thefollowing procedure in a static-safe environment with proper electro-staticdischarge controls in place.DPO7000/C, DPO70000/B/C/D/DX, DSA70000/B/C/D, and MSO70000/C/DXSeries InstrumentsLoosen the thumbscrews on the removabledrive panel.Pull the removable drive out from theinstrument.DPO5000/B and MSO5000/B Series InstrumentsRemove the drive cover.Loosen the thumbscrew on the removable drive panel.Pull the removable drive out from the instrument.DisablingUSB and CD-RW CapabilityThe following instructions describe how to disablethe built-in USB and CD-RW capability. Using the BIOS disables thedevices for DOS and Windows programs, while the Windows Device Managerdisables the devices for Windows programs. These procedures disableboth USB and the CD-RW to prevent their use.If you disable the USB, CD-RW, and LAN inthe following procedures, you cannot write new firmware to the harddrive.

Sanitize or replace the drive in a mannerthat meets local and any other security requirements that you have.To see the size of the drive, refer to the(C:) local disk properties window.If your instrument did not ship with an OSRestore disk, be sure that you create OS Restore CD-ROMs before scrubbingthe hard drive/solid state drive or moving the instrument into a securearea. For more information see Creating Operating System Restore CD-ROMsin your instrument User manual or in the 071-2501-xx Read This First.On MSO5000/B and DPO5000/B Series instruments, if youscrub the drive, you must install a new drive that has the OS andinstrument software already installed.After the drive is sanitized or replaced, the operatingsystem and instrument software can be reinstalled. Following reinstallationof the operating system and product software, you must run the SignalPath Compensation (SPC) procedure in the Utilities menu after a 20-minutewarm-up period. This returns the instrument hard drive/solid statedrive to the initial state shipped from the factory.Scrubbing the drive will not affect calibrationof the instrument, since the factory calibration constants are storedon the acquisition board, entirely separate from any acquisition dataor user files. You can completely erase or remove any secure datawithout affecting the calibration of the instrument. You can alsocalibrate the instrument in a nonsecure site, and then use the instrumentin a secure area without recalibration.PC Ram SizeTo see the size of the PC RAM in the instrument,refer to the General tab of the Windows System Properties dialog box.Built-In Security Features-->When to Use Tek SecureUse Tek Secure when you want to erase and overwrite the standardwaveform and setup memories.-->What Tek Secure DoesTek Secure capability is present in DPO7000, DPO70000,DPO70000B, DSA70000, DSA70000B, and MSO70000 instruments. PressingTek Secure erases and overwrites all of the standard waveform andsetup memories. User waveform and setup memories and files not inthe instrument default locations are not erased.The standard waveform memories, stored on the hard drive, areoverwritten with an “empty,” all zeros pattern. Thestandard setup memories, stored on the hard drive, are overwrittenwith the factory default front-panel setup. The current front-panelsetup is also overwritten with the default factory setup.Using Tek Secure does not affect calibration of the instrumentbecause the calibration constants are stored on the Acquisition board,completely separate from any acquisition data. This allows completeerasure/removal of any secure data without affecting the instrumentcalibration. It also allows the instrument to be calibrated in a nonsecuresite and then used in a secure area without the need for recalibration.If you remove and store or destroy the hard drive, you do notneed to use Tek Secure because the data that will be secured is onthe hard drive.-->TroubleshootingHow to Clear or Sanitize a Non-Functional InstrumentIf your instrument is not functioning, you may proceedas follows:Hard Drive/Solid State DriveRemove the drive and return the product to Tektronix.A new drive will be installed and the instrument will be repairedand adjusted as necessary. Alternatively you may use the RemovableHard Drive/Solid State Drive procedure before returning the productto Tektronix. For removal instructions, refer to the instrumentservice manual, available on the Tektronix Web site at www.tektronix.com/manuals.CD-RW/DVD ROM DriveOn instrument with a CD-RW/DVD ROM drive, removeall CDs and/or DVDs. These can be stored or destroyed according tothe internal policies of your organization.External Memory DevicesRemove any attached USB flash drive or externalhard drives from the instrument before returning the instrument toTektronix for repair.Refer to your company’s internal policiesregarding handling or disposal of the external memory device.ChargesReplacement of any missing hardware will be chargedaccording to the rate at the time of replacement.How to Recover from Clearing or Removing the InstrumentMemoryAfter the hard drive/solid state drive is sanitized,the operating system and instrument software must be reinstalled.On instruments with a CD/DVD ROM drive, the restore software opensautomatically if the CD/DVD drive is the first bootable device. Ifthe CD/DVD drive is not the first bootable device, enable it as thefirst bootable device before performing a restore from the CD-ROMs.On MSO5000/B and DPO5000/B Series instruments, if youscrub the hard drive/solid state drive, you must install a new drivethat has the OS and instrument software already installed.Change LogDocument part numberRevision dateChange description077-0245-0210-14-2010Added Reference section to Preface.
