Preface
This document helps customers with data security concerns to sanitize or remove memory devices from the MTS400 Series Test Systems.
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.

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. 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 retainedwhen 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-modiable. 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.

Troubleshooting
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:
Enhanced IP (GigE) Interface Card
This card stores a list of IGMP subscription addresses in use. If this needs to be sanitized, then it must be returned to Tektronix.
RF Interface Cards (QAM (Annex B), 8VSB, PSK, COFDM)
These cards store immediate values in memory, for example, current frequency. These values are lost when power is removed.
Hard Drives (IDE and SCSI)
Remove the hard drive. Store the removed hard drive in a secure area or destroy it.
How to Recover from Clearing or Removing the Instrument Memory
Follow the procedures in the MTS400 MPEG Test System Getting Started Manual (Tektronix part number: 071-1505-xx) to reinstall the operating system and the MTS400 applications.
