m

emory to deny access to previously unsecured info rmation.

 Demo setups: Demonstration applications that come loaded on the instrument; you cannot modi f y them.
 Direct method of modification: You can modify data directly.
 Erase: Equivalent to clear (see above).
 Indirect method of modification: The instrument system reso urces modify the data; you cannot modify

it.

 Instrument declassification: Procedures that must be completed before an instrument can b e remove

rom a secure environment. Declassification procedures include memory sanitization and memory

f
removal.

 Media storage and data export device: Devices that can be used to store or export data from the

i

nstrument, such as a USB port.

 Nonvolatile memory: Data is retained when the instrume nt power is turned off.
 Protected user data area: Contains data that is protected by a password.
 Remove: Clears instrument data by physically removing the memory device from the instrument.

or technology. This is typically used when the device wil l be m oved (temporarily or permanently) from

ecured area to a nonsecured area.

instructions work for all instruments listed in the Products (on page 1

All of these instruments contain three sets of volatile and nonvolatile memory as described below.
The MASTER (U13 on the 2450-140 board) contains instrument logic, calibration data, and customer s cripts,

readings, and data:

 Two 16 MB nonvolatile NOR FLASH chips on the Digital board
 Two 128 MB volatile DDR2 SDRAM chips on the Digit al board
