Preface
This document helps customers with data security concerns to sanitize or remove
memory devices from the MTM400A and RFM300 DTV Monitors.
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.
Supported Products MTM400A and RFM300 DTV Monitors.
Related Documents The MTM400A and RFM300 DTV Monitors Technical Reference, Tektronix
part number 077-0175-xx, is available on the Tektronix Web site at
www.tektronix.com/manuals.
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. This refers to 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. 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-modifiable. The user can write to the memory device during normal
instrument operation, using the instrument interface or remote control.

2. Remove the top cover.
3. Push the NVRAM clear button on the monitor’s Processor card for 10 seconds.
4. Replace the cover.
NOTE. Removing the top cover of the instrument and accessing the NVRAM clear
button are described in the MTM400A and RFM300 DTV Monitors Technical
Reference (Tektronix part number: 077-0175-xx).

How to Clear or Sanitize a Non-Functional Instrument
If your instrument is not functioning and you need to clear or sanitize it, proceed
as follows:
Main Processor Card Remove power and remove battery; this will clear any configuration information.
The MAC and IP addresses are held in an EPROM. If this needs to be sanitized,
the instrument must be returned to Tektronix.
NOTE. Removing the instrument’s top cover and access to the battery are
described in the MTM400A and RFM300 DTV Monitors Technical Reference,
(Tektronix part number: 077-0175-xx).
Gigabyte Ethernet
Interface Card
This card uses data which is stored on the Main Processor card. Clearing the Main
Processor card clears all data associated with the Gigabit Ethernet card.
RF Interface Cards The RF interface cards store immediate values in memory, for example, current
frequency. These values are lost when power is removed.
How to Recover from Clearing or Removing the Instrument Memory
Follow the procedures in the MTM400A and RFM300 DTV Monitors Quick
Start User Manual to set the network, time, and license information, and then
reconfigure tests to your application.
