This document describes instrument security features and the steps to declassify an instrument through
memory clearing, sanitization or removal.
For additional information, go to:
http://www.keysight.com/find/security
Be sure that all information stored by the user in the instrument that needs to be saved is
properly backed up before attempting to clear any of the instrument memory. Keysight
Technologies cannot be held responsible for any lost files or data resulting from the clearing of
memory. Be sure to read this document entirely before proceeding with any file deletion or
memory clearing.

Memory Type: Flash
Memory Size: 1024 Megabit
Bank 0 (256 Megabit)
Memory Function: Contains the instrument firmware
Memory Function: Not used
Bank 2 (256 Megabit)
Memory Function
Bank 3 (256 Megabit, only first half (128 Megabit) is used, second half (128 Megabit) is not used)
Memory Function: Contains User saved setup information such as: save/recall, frequency-dependent offset tables
only)
Instrument Memory
This section contains information on the types of memory available in your instrument. It explains the size
of memory, how it is used, its location, volatility, and the sanitization procedure.
User Modifiable (Y/N): N Removable (Y/N): N Volatile (Y/N): N
Memory Erase Processes:
- No user settable information in this memory
- No inherent security risk in this memory
Bank 1 (256 Megabit)
: Not used
User Modifiable (Y/N): Y (first half (128 Megabit)
Memory Erase Processes:
- REMOTE IO COMMAND : SERVice:SECure:ERASe does the following to the entire 256 Megabit:
o All memory locations are overwritten by
Writing each location with all zeros
Writing each location with a single character
o The entire memory bank is erased
The memory is erased in compliance with the manufacturers datasheet
The memory is reformatted to re-initialize the internal file system
Any factory-default file content is restored
- After that, user can try to read back save/recall states or FDO tables to verify the erase process is
completed
Removable (Y/N): N Volatile (Y/N): N

Memory Type: EEPROM #1 (Analogue Board)
Memory Size: 128 Kilobit
Memory Function: Contains basic instrument configuration information such as: model number, serial number,
calibration date and place, sensor calibration data, sensor type and tracking number
User Modifiable (Y/N): N
Removable (Y/N): N
Volatile (Y/N): N
Memory Erase Processes:
Memory Type: EEPROM #2
Memory Size: 128 Kilobit
FPGA board information.
User Modifiable (Y/N): N
Removable (Y/N): N
Volatile (Y/N): N
Memory Erase Processes:
- No user setup information contained in this memory.
- When the instrument is turned on, all the information is downloaded from the EEPROM to be used by the
instrument.
- The EEPROM is not user-accessible via the remote interface.
- No inherent security risk in this memory
Memory Function: Contains basic instrument configuration information such as: model number, serial number and
- No user setup information contained in this memory.
- When the instrument is turned on, all the information is downloaded from the EEPROM to be used by the
instrument.
- The EEPROM is not user-accessible via the remote interface.
- No inherent security risk in this memory

Memory Erase Processes:
Memory Type: SDRAM
Memory Size: 1024 Megabit
User Modifiable (Y/N): N
Removable (Y/N): N
Volatile (Y/N): Y
Memory Erase Processes:
Memory Function: Contains measurement logic and board control logic.
User Modifiable (Y/N): N
Removable (Y/N): N
Volatile (Y/N): Y
Memory Erase Processes:
Memory Function: Contains basic instrument configuration information such as: part number, serial number and RF
assembly information
User Modifiable (Y/N): N Removable (Y/N): N Volatile (Y/N): N
- No user setup information contained in this memory.
- When the instrument is turned on, all the information is downloaded from the EEPROM to be used by the
instrument.
- The EEPROM is not user-accessible via the remote interface.
- No inherent security risk in this memory
Memory Function: Random Access Memory that temporary stores sensor’s information such as correction data
upon power up
- Data stored in SDRAM is erased when device is powered down.
Memory Type: FPGA Memory Size: 4824 Kilobit
- Data stored in FPGA is erased when device is powered down.
