memory devices from the MTM400A MPEG Transport Stream Monitor. 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 MPEG Transport Stream Monitor. Related Documents The MTM400A MPEG Transport Stream Monitor Technical Reference, Tektronix part number 071-2495-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.

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. Volatile memory. Data is lost when the instrument is powered off. iv MTM400A Declassification and Security Instructions

Remove power. 2. Remove the top cover. 3. Push the NVRAM clear button on the MTM400A Processor card for 10 seconds. 4. Replace the cover. NOTE. Removing the top cover of the instrument and accessing the NRVRAM clear button are described in the MTM400A Transport Stream Monitor Technical Reference (Tektronix part number: 071-2495-xx). 2 MTM400A Declassification and Security Instructions

Clear IGMP Subscriptions (Gigabit Ethernet Interface card only) Use the following procedure to clear the IGMP subscriptions. 1. Open the MTM400A monitor user interface. 2. Open the Stream – Input Card screen. 3. Select the IGMP sessions display. 4. Select multi-IGMP mode. 5. For each address to be deleted, type the IP address in the IGMP delete box and press Enter. Recovering from NVRAM and IGMP subscription clear To recover from the Clear NVRAM and Clear IGMP Subscription procedures, follow the setup procedures described in the MTM400A MPEG Transport Stream Monitor Quick Start User Manual (Tektronix part number: 071-2492-xx).

If your instrument is not functioning and you need to clear or sanitize it, proceed as follows: MTM400A 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 MPEG Transport Stream Monitor Technical Reference, (Tektronix part number: 071-2495-xx). Gigabyte Ethernet Interface Card This card stores the list of IGMP subscription addresses that are in use. If this card needs to be sanitized, the instrument must be returned to Tektronix. 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 MPEG Transport Stream Monitor Quick Start User Manual (Tektronix part number: 071-2492-xx) to set network, time, and license information, and then reconfigure tests to your application.
