Basic Operation

Using Security Functions

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.

NOTE This function is different than pressing Utility > Memory Catalog > 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	All addressable locations are overwritten with random characters.
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.)

To carry out this function, press Utility > Memory Catalog > More (1 of 2) > Security > Erase and Overwrite All > Confirm Overwrite.

Erase and Sanitize All

This function performs the same actions as Erase and Overwrite All and then adds more overwriting actions. After executing this function, you must manually perform some additional steps for the sanitization to comply with Department of Defense (DoD) standards. These actions and steps are described below.

SRAM	All addressable locations are overwritten with random characters.
DRAM	All addressable locations are overwritten with a single character. You must then power off the instrument to
	purge the memory contents.
Hard Disk	All addressable locations are overwritten with a single character and then a random character. (This is
	insufficient for top secret data, according to DoD standards. For top secret data, the hard drive must be removed
	and destroyed.)

To carry out this function, press Utility > Memory Catalog > More (1 of 2) > Security > Erase and Sanitize All >
