Using Security Functions
This document describes how to use the signal generator’s security functions to protect and remove classified
proprietary information stored or displayed in the instrument.
The information in this document is presented with the assumption that you are familiar with the basic operation of
the signal generator. If you are not comfortable with using the instrument’s menu structure, and functions such as
setting power level and frequency, refer to the User’s Guide and familiarize yourself with basic instrument operation.
All security functions described in this section also have an equivalent SCPI command for remote operation. (Refer to
the SCPI Command Reference for more information.)
Configuring the MXG ATE
NOTE For the N5161A/62A, the softkey menus and features mentioned in this guide are only available through the
Web-Enabled MXG or via SCPI commands. Refer to the Installation Guide, the Programming Guide, and to
the SCPI Command Reference.
The MXG ATE N5161A and N5162A, are blank front panel versions of the N5181A and N5182A.
Since the MXG ATE N5161A and N5162A, have no front panel softkeys similar to the N5181A/82A signal generators,
in order to access the features mentioned in this Security Features document, two options remain available
1. SCPI commands (refer to the SCPI Command Reference) or
2. the instrument’s Web- Enabled page.

Understanding Memory Types
1
The signal generator has several memory types, each used for storing a specific type of data. Before removing sensitive
data, it is important to understand how each memory type is used.
• MXG Memory on page 4
• ESG/PSG Memory on page 6
• E8663B Memory on page 9

For the N5161A/62A the softkey menus and features mentioned in this guide are only available through the Web-Enabled M XG
or via SCPI commands. Refer to “Configuring the MXG ATE” on page 2, the Installation Guide, the Programming Guide, and to
the SCPI Command Reference.

Removing Sensitive Data from Memory
1
This section describes several security functions you can use to remove sensitive data stored in the signal generator
when moving it from a secure development environment.
CAUTION The following functions do not erase or sanitize external media connected to the MXG’s USB port. You
must use some other method to dispose of information on this media.
CAUTION Do not use the Erase All, Erase and Overwrite All, Erase and Sanitize All, Erase, Overwrite, or
Sanitize
procedure with any of these firmware revisions:
E44x8C: C.04.84, C.04.86, C.04.95
E82x7D: C.04.81, C.04.85, C.04.92
E8663B: C.04.90
If you have one of those revisions, please upgrade immediately to newer firmware as follows:
E44x8C: upgrade to C.04.96 or later
E82x7D: upgrade to C.04.94 or later
E8663B: upgrade to C.04.93 or later
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,
typically taking less than one minute (the exact time depends on the number of files).
On the MXG, press: File > More > Security > Erase All > Confirm Erase
On the ESG/PSG/E8663B, press: Utility > Memory Catalog > More (1 of 2) > Security > Erase All > Confirm Erase
NOTE This function is different than the one that deletes all user files but does not reset the table editors:
MXG: File > Delete All Files
ESG/PSG/E8663B: Utility > Memory Catalog > More (1 of 2) > Delete All Files
Erase and Overwrite All
This function 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 5220.22M.
SRAM (Not applicable to the MXG) 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.
Hard Disk (E4438C Option 005, E8267D Option 005, and E8267C Option 005 only) All addressable locations are
overwritten with a single character. (This is insufficient for top secret data, according to the NISPOM DOD
5220.22M. For top secret data, the hard drive must be removed and destroyed.)
Flash Drive (E8267D Option 009 only) All addressable locations are overwritten with a single character. (This is

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 MXG, press: Utility > Power On/Preset > Restore System Settings to Default Values > Confirm Restore Sys Settings to
Default Values
• On the ESG/PSG/E8663B front panel, press: Utility > Power On/Preset > Restore System Defaults >
Confirm Restore Sys Defaults
• Or send this command to the MXG/ESG/PSG/E8663B: :SYSTem:PRESet:PERSistent
LAN Setup
The LAN setup (hostname, IP address, subnet mask, and default gateway) information is not defaulted with a signal
generator power-on or *RST command. This information can only be changed or cleared by entering new data.
User IQ Cal File (Vector Models Only)
When a user- defined IQ calibration has been performed, the cal file data is removed by setting the cal file to default,
as follows:
• On the front panel, press: I/Q > I/Q Calibration > Revert to Default Cal Settings
• Or send this command to the MXG: :CAL:IQ:DEF
• And send these commands to the ESG/PSG/E8663B:
— :CAL:IQ:DEF
— :CAL:WBIQ:DEF
Agilent ESG/MXG/PSG/E8663B Signal Generators Security Features 11
Using the Secure Mode
The secure mode automatically applies the selected Security Level action the next time the instrument’s power is cycled.
Setting the Secure Mode Level
1. On the MXG, press: File > More > Security > Security Level
On the ESG/PSG/E8663B, press: Utility > Memory Catalog > More (1 of 2) > Security > Security Level
2. Choose from the following selections:
None − equivalent to a factory preset, no user information is lost
Erase − equivalent to Erase All
Overwrite − equivalent to Erase and Overwrite All
Sanitize − equivalent to Erase and Sanitize All
Activating the Secure Mode
CAUTION Once you activate secure mode (by pressing Confirm), you cannot deactivate or decrease the security level;
On the MXG press: File > More > Security > Enter Secure Mode > Confirm
On the ESG/PSG/E8663B, press: Utility > Memory Catalog > More (1 of 2) > Security > Enter Secure Mode > Confirm
The Enter Secure Mode softkey changes to Secure Mode Activated.
the erasure actions for that security level execute at the next power cycle. Once you activate secure mode,
you can only increase the security level until you cycle power. For example, you can change Erase to
Overwrite, but not the reverse.
After the power cycle, the security level selection remains the same, but the secure mode is not activated.

Error Messages and Secure Environments
If you cannot upgrade the firmware prior to using the security features, Agilent will help you to recover from error
messages which may appear after executing the security functions. The error messages indicate that instrument system
files have been erased. The following list shows some of the possible error messages:
• −256, File name not found; /SYS/LICENSE.TXT
• 617, Configuration Error; License file not found. Creating empty one.
• A missing or damaged system file was encountered while trying to diagnose the system.
Even though these errors may occur, the security function has completely sanitized the signal generator. If the signal
generator is located in a secure environment, it is safe to remove it. After removing it from the secure area, follow the
process below to recover the lost system files.
