Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from the Tektronix TTR503A and TTR506A vector network
analyzers (VNAs) and the TCAL500 electrical calibration kits.
The VNAs have a data storage (memory) device. The instructions in this manual
describe how to clear or sanitize the memory device.
The VNA and the TCAL500 do not contain any media or export devices that
require declassification instructions.
Reference The procedure in this document is written to meet the requirements specifiedin:
NISPOM, DoD 5220.22–M, Chapter 8
ISFO Process Manual for Certification & Accreditation of Classified Systems
under NISPOM
Products The security instructions apply to these Tektronix products:
TTR503A
TTR506A
TCAL500-35F, TCAL500-35MF, TCAL500-35M
TCAL500-NF, TCAL500-NMF, TCAL500-NM
Required documents No external documents are required to perform the procedures in this document.
Terms 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 can be 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.
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, puttingthe
instrument in Standby mode does not qualify as powering off. For these
TTR500 Series and TCAL500 Declassification and Security Instructions iii

Preface
products, you will need to either press a rear-panel OFF switch or remove the
power source from the instrument.
Remove. This isaphysicalmeanstoclearthedatabyremovingthememory
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.
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.
Device terms 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 or sanitize a non-functioning instrument
Clear or sanitize a non-functioning instrument
If your instrument is not functioning, return the instrument to Tektronix for
repair. A Tektronix service professional can reprogram the USB device embedded
in the VNA. No user data is stored on the instrument when it is disconnected
from a power supply.
To clear or sanitize the instrument:
1. Enable USB storage in activation manager in VectorVu-PC.
2. Use a secure erase tool to erase the USB drive.
Charges Replacement of any missing hardware will be charged according to the rate at
the time of replacement.
