Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from the RSA3303B, RSA3308B, and RSA3408B Real-Time
Spectrum Analyzers.
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:
RSA3303B
RSA3308B
RSA3408B
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.

iv RSA3303B, RSA3308B, & RSA3408B Declassification and Security
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.

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.

Clear and Sanitize Procedures
2RSA3303B, RSA3308B, & RSA3408B Declassification and Security
Clearing Hard Disk Drives If your organization’s security protocols allow the use of software to purge or
sanitize hard drives, you can use commercial software to erase free space on the
hard drive before sending the instrument out for upgrades or repair. Follow the
instructions that come with the software to ensure that the erasure of sensitive data
from the hard drive complies with your organization’s security protocols.
Sequence for clearing secure data from a hard drive:
1. Perform a System Recovery
2. Upgrade the instrument application software if necessary.
3. Erase the free space on the hard drive using commercial software.
Fixed Hard Drive Removal For a detailed removal and replacement procedure for the fixed hard drive, see the
RSA3303B & RSA3308B Service Manual (Tektronix part number 071-2367-XX)
or RSA3408B Service Manual (Tektronix part number 071-2366-XX). Refer to the
Removal and Installation Procedures section of the manual.
WARNING. Only qualified service personnel should perform the hard drive
removal procedure. Read the Service Safety Summary and the General Safety
Summary in the RSA3303B & RSA3308B Service Manual (Tektronix part number
071-2367-XX) or RSA3408B Service Manual (Tektronix part number
071-2366-XX) before proceeding.
WARNING. Before working on the spectrum analyzer, disconnect the power cord
from the line voltage source. Failure to do so could cause serious injury or death.
CAUTION. To avoid damaging the hard drive, perform the procedure in a
static-safe environment with proper electro-static discharge controls in place.
