Terminology
The following terms may be used in this document:
Clear: Removes data on media or in memory before reusing it in a secured area. Clears all reusabl
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.
Sanitize: Eradicates instrument data from media and memory so it cannot be recovered by other means
or technology. This is typically used when the device wil l be m oved (temporarily or permanently) from
ecured area to a nonsecured area.
s
Scrub: Directly retrieve and clear the contents of the mem ory device.
User accessible: You can directly retriev e the contents of the memory device.
User data: Measurement data that represents signals that you connect to the instrument.
User modifiable: You can write to the memory device during normal instrument operation using t
front-panel interface or remote control.
User settings: Instrument settings that y ou can change.
Volatile memory: Temporary memory; data is lost when the instrument is turned of f.

Description of memory
All of these instruments share common volatile and n onvolatile memory components. This document and these
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

The BLASTER (U1 on the 2450-140 board) contain s inst rument logic, calibration data, and customer scripts,
readings, and data:
Two 16 MB nonvolatile NOR FLASH chips on the Digital board
One 128 MB volatile DDR2 SDRAM chip on the Digital board
The DISPLAY (U1 on 2450-110 board) contains instrument logic and customer setups and data:
Two 16 MB nonvolatile NOR FLASH chips on the Digital board
One 128 MB Volatile DDR2 SDRAM chip on the Digital board
Each instrument contains a battery-backed up clock that is used to generate timestamps. It does not
store data.
Older Model 2450s (Digital/Display board revisio n C) have two volatile DDR2 SDRAM chips for the
BLASTER and DISPLAY. However, the process for clearing and sanitizing data is identical.
Memory devices
The following tables list the volatile and nonvolatile memory devices in the standard instrument and l i sted
options.

Clearing data
You can use TSP scripts to clear data. You can run these scripts from the front panel using a flash drive or run
them remotely.
Clearing data scripts and setups
To clear the data scripts and setups:
1. Set the correct command set:
*LANG TSP
2. Erase user strings from nonvolatile memory:
for name in userstring.catalog() do
userstring.delete(name)
end
3. Erase scripts and configuration lists from nonvol atile memory:
for name in script.user.catalog() do
script.delete(name)
end
4. Source-measure instruments only (2450, 2460, 2461, and 2470): Set the GPIB address to the fact ory
default:
gpib.address = 18
5. Digital multimeters only (DMM7510): Set t he GP IB address to the factory default:
gpib.address = 16
6. Set the command set to SCPI:
*LANG SCPI
Resetting the instrument
These steps only reset the volatile memory. Resetting the volatile memory restores the instrument to t he factory
defaults.
If you are using the SCPI command set:
*RST
If you are using the TSP command set:
reset()

LAN reset
LAN RESET resets the LAN settings and the instrument password to the factory default values.To do this reset,
insert a straightened paper clip into the hole label ed LAN RESET.
LAN RESET is on the rear panel on the instruments. S ee f i gure below.
Figure 1: LAN Reset location
Sanitize instrument data
The only way to sanitize data from an instrument is to physically remove the nonvolatile memory devices listed
in the tables above.
Sanitize a nonfunctional instrument
To sanitize a nonfunctional instrument, r em ove the Digital and Display boards and return the instrument t o
Keithley Instruments for installation of replacement boards.
