Working in a Secure Environment
Removing Data from Memory (Option 006 Only)
Erase and Overwrite All
This performs the same actions as Erase All, plus it clears and overwrites the various memory types
in compliance with the National Industry Security Program Operating Manual (NISPOM) DoD
5220.22–M.
CPU Flash Overwrites all addressable locations with random characters and then erases the
flash blocks. This accomplishes the same purpose as a chip erase. System files are
restored after erase.
To Start: Press File > More > Security > EraseandOverwriteAll > Confirm Erase
Erase and Sanitize All
This performs the same actions as Erase and Overwrite All and then adds more overwriting actions.
After executing this function, you must manually perform the additional steps described below for the
sanitization to comply with the National Industry Security Program Operating Manual (NISPOM) DoD
5220.22–M.
To Start: Press File > More > Security > Erase and Sanitize All > Confirm Sanitize
Removing Persistent State Information Not Removed During Erase
Persistent State
The persistent state settings contain instrument setup information that can be toggled within
predefined limits such as display intensity, contrast and the GPIB address. In vector models, the user
IQ cal is also saved in this area.
The following key presses or SCPI commands can be used to clear the IQ cal file and to set the
operating states that are not affected by a signal generator power–on, preset, or *RST command to
their factory default:
Instrument Setup
• On the Agilent MXG front panel, press: Utility > Power On/Preset > Restore System Settings to Default
Values > Confirm Restore Sys Settings to Default Values
• Or send this command to the Agilent MXG: :SYSTem:PRESet:PERSistent
CPU Flash Overwrites all addressable locations with random characters and then erases the
flash blocks. This accomplishes the same purpose as a chip erase. System files
are restored after erase.
BBG Persistent
Memory (Flash)
(Vector instruments only) Overwrites all addressable locations with random
characters and then erases the flash blocks. This accomplishes the same purpose
as a chip erase. System files are restored after erase.
