Working in a Secure EnvironmentRemoving Data from Memory (Option 006 Only)Erase and Overwrite AllThis performs the same actions as Erase All, plus it clears and overwrites the various memory typesin compliance with the National Industry Security Program Operating Manual (NISPOM) DoD5220.22–M.CPU Flash Overwrites all addressable locations with random characters and then erases theflash blocks. This accomplishes the same purpose as a chip erase. System files arerestored after erase.To Start: Press File > More > Security > Erase and Overwrite All > Confirm EraseErase and Sanitize AllThis 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 thesanitization to comply with the National Industry Security Program Operating Manual (NISPOM) DoD5220.22–M.CPU FlashBBG PersistentMemory (Flash)To Start:Overwrites all addressable locations with random characters and then erases the flashblocks. This accomplishes the same purpose as a chip erase. System files are restored aftererase.(Vector instruments only) Overwrites all addressable locations with random characters andthen erases the flash blocks. This accomplishes the same purpose as a chip erase. Systemfiles are restored after erase.Press File > More > Security > Erase and Sanitize All > Confirm SanitizeRemoving Persistent State Information Not Removed During ErasePersistent StateThe persistent state settings contain instrument setup information that can be toggled withinpredefined limits such as display intensity, contrast and the GPIB address. In vector models, the userIQ 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 theoperating states that are not affected by a signal generator power–on, preset, or *RST command totheir factory default:Instrument Setup• On the Agilent MXG front panel, press: Utility > Power On/Preset > Restore System Settings to DefaultValues > Confirm Restore Sys Settings to Default Values• Or send this command to the Agilent MXG: :SYSTem:PRESet:PERSistentAgilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 311
