Preface
This document helps customers with data security concerns to sanitize or remove memory devices from the DSA8300
Digital Serial Analyzer and its related sampling modules and module accessories.
The DSA8300 has data storage (memory) devices and data output devices (USB ports). Some of the modules have memory
devices. 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.
Reference The procedures in this document are written to meet the requirements specified in:
NISPOM, DoD 5220.22–M, Chapter 8
ISFO Process Manual for Certification & Accreditation of Classified Systems under NISPOM
Products The following Tektronix products are covered by this document:
DSA8300 Digital Serial Analyzer
80A00 series Accessory plug-in modules
80C00 series Optical plug-in sampling modules
80E00 series Electrical plug-in sampling modules
80N01 series electrical sampler extender
80X00 series electrical sampler extenders
82A00 series Phase Reference sampling modules
DSA8300 Instrument, Sampling Modules Declassification and Security Instructions iii

Preface
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.
Instrument Declassification. A term that refers to procedures that must be undertaken before an instrument is
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.
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. This is equivalent to sanitize.
User Accessible. User is able to directly retrieve the memory device contents.
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.
Nonvolatile memory. Data is retained when the instrument is powered off.
iv DSA8300 Instrument, Sampling Modules Declassification and Security Instructions

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 of 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 data.

Clear and sanitize procedures
General media sanitizing
information
Turn power off for at least 20 seconds to clear all volatile memory. All user storable data (waveforms and instrument
settings) are stored on the removable hard drive, on a writeable CD/DVD drive, or through an attached USB media device,
such as a flash drive. The hard drive is located on the rear panel. The writeable CD/DVD drive is located on the front
panel. The USB ports are located on the rear panel (4 each), and front panel (1 each).
To sanitize the hard drive, remove the hard drive from the instrument and store or destroy. Additional hard drives can be
purchased from Tektronix. Alternately, 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 sanitized (scrubbed),
reinstall the operating system and instrument software (in that order) using the DSA8300 Operating System Restore and
Product Software restore media that came with the instrument.
Reinstalling the operating system or the product application software will not affect calibration of the instrument. All
mainframe-related calibration constants are stored in nonvolatile memory on the timebase, EFE, or OFE boards, rather than
on the hard drive. This allows complete erasure/removal of any secure data without affecting oscilloscope calibration. It
also allows the instrument to be calibrated in a non-secure site then used in a secure area without need for recalibration.
Read-write CD/DVD drives are standard on this product. Remove all CDs or DVDs. Rewritable CD/DVD discs can be
formatted, stored, or destroyed. Nonrewritable CD discs can be stored or destroyed.
Five USB ports are standard on this product. Remove USB media devices and sanitize, store, or destroy them.
Disabling USB and
DVD-ROM/CD-RW devices
The following instructions describe how to disable USB ports and DVD-ROM/CD-RW capability. Disabling from
BIOS disables the devices for DOS and Windows programs; disabling from the Windows Device Manager disables the
devices for Windows programs.
NOTE. If you disable the USB and/or DVD-ROM/CD-RW, you cannot install new firmware from these devices to the
hard drive. To do so, you must enable one of these items.
To disable USB DOS from the BIOS.

To sanitize the removable
hard drive
All user-storable data is stored on the rear-panel removable hard drive. Sanitize or replace the hard drive in a manner
that meets all security requirements for your location.
After the hard drive is sanitized or replaced, reinstall the operating system (OS) and instrument software (in that order)
using the provided OS recovery media and instrument application software media.
Scrubbing the hard drive does not affect calibration of the instrument because the factory calibration constants are stored on
the PPC, timebase, EFE, and OFE boards, entirely separate from any acquisition data or user 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.

Troubleshooting
How to clear or sanitize a nonfunctional instrument
If your instrument is not functioning, perform the following actions and return the instrument to Tektronix for repair.
Describe the initial problem with the product. Tektronix will install replacement parts and then repair and return the
instrument.
Hard Disk Drives Remove the hard disk by unscrewing the two retaining screws and pulling out the hard drive tray. Store the drive in a
secure location. A new hard drive will be installed and the instrument will be repaired and adjusted as necessary.
Read/Write CD/DVD Drives Remove all CDs or DVDs from the DVD-ROM/CD-RW drive. If the instrument cannot power on, insert a small paper
clip into the hole next to the DVD-ROM/CD-RW drive drawer latch and push to release the drawer and remove the disc.
Store or destroy the disc according to the security policies of your organization.
External memory devices Remove any USB flash drives or external hard drives from the instrument.
Refer to your company’s internal policies regarding handling or disposal of the external memory device.
How to recover from
sanitizing or installing a
new (empty) instrument
hard drive
After the hard drive is sanitized or replaced with a new (empty) hard drive, the operating system and instrument software
must be reinstalled (in that order) from the DSA8300 OS restore and application software install media. The restore
software runs automatically if the DVD-ROM/CD-RW drive is the first bootable device. If the DVD-ROM/CD-RW drive
is not the first bootable device, press the F2 key during instrument power-on to open the instrument BIOS window and
enable the DVD-ROM/CD-RW drive as the first bootable device before performing a restore from the recovery media.

How to clear or sanitize a working 80C00 series module
This section covers how to clear or sanitize a 80C01, 80C02, 80C07B, 80C08/B/C/D, 80C10/B/C, 80C11/B, 80C12/B,
80C14, 80C15, or 80C25GBE Optical Sampling Module nonvolatile memory.
The nonvolatile memory in these products contains a single user storable instrument parameter (User Wavelength),
composed of both a wavelength value and an associated scale factor value. Restoration to factory defaults is only necessary
if either of the values are different from the factory defaults.
To check the current 80C00
module user wavelength
settings
The following procedure checks the current module user wavelength settings. This procedure requires sending
programmable interface (PI) commands to the instrument using a GPIB or other remote command access interface. See the
TekScope application Help menu to access the instrument online help and programmer manual.
1. Power down the instrument and insert the optical module into the upper left (CH1) or right (CH3) large slot. Use the
appropriate channel number when sending commands to a module.
2. Power up the instrument and wait for the oscilloscope application to become active.
3. Use the following table for the applicable module(s) to send the applicable programmable interface query commands to
the instrument. Verify if each returned response matches the listed factory default User Wavelength or User Wavelength
Scale setting. If the returned values are different than the factory default, restore the default values for the applicable
modules. (Seepage16,To restore the user wavelength factory default values.)
