Removing Sensitive Data from PSG Memory

When moving the PSG from a secure development environment, you can
remove any classified proprietary information stored in the instrument. This
section describes several security functions you can use to remove sensitive
data from your instrument.
Erase All
This function removes all user files, user flatness calibrations, user I/Q
calibrations, and resets all table editors with original factory values, ensuring
that user data and configurations are not accessible or viewable. The
instrument appears as if it is in its original factory state, however, the memory
is not sanitized. This action is relatively quick, taking less than one minute.
To carry out this function, press Utility > Memory Catalog > More (1 of 2) >
Security > Erase All > Confirm Erase.
This function is different than pressing Utility > Memory Catalog >
NOTE
More (1 of 2) > Delete All Files, which deletes all user files, but does not reset
the table editors.
Erase and Overwrite All
This function performs the same actions as Erase All and then clears and
overwrites the various memory types in accordance with Department of
Defense (DoD) standards, as described below.
SRAM All addressable locations are overwritten with random characters.
CPU Flash All addressable locations are overwritten with random characters and then the flash blocks are erased. This
accomplishes the same purpose of a chip erase, however, only the areas that are no longer in use are erased
and the factory calibration files are left intact. System files are restored after erase.
DRAM/SDRAM Follow the Department of Defense (DoD) manual's requirements. The instrument must be powered off to
purge the memory contents. The instrument must remain powered off in a secure location for 3 minutes.
Hard Disk All addressable locations are overwritten with a single character. (This is insufficient for top secret data,
according to DoD standards. For top secret data, the hard drive must be removed and destroyed.)
Flash Drive All addressable locations are overwritten with a single character. (This is insufficient for top secret data,
according to DoD standards. For top secret data, consult with your local security officer for approved
procedures.)
To carry out this function, press Utility > Memory Catalog > More (1 of 2) >
Security > Erase and Overwrite All > Confirm Overwrite.
