304 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
Working in a Secure Environment
Removing Data from Memory (Option 006 Only)
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 Agilent MXG: :CAL:IQ:DEF
Secure Mode
CAUTION Once you activate secure mode (by pressing Confirm), you cannot deactivate or decrease
the security level; 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 secure mode is
not activated.
To avoid the loss of data, GPIB settings, or current user instrument states that have not
been permanently saved to non-volatile memory, the MXG should always be powered
down either via the MXG's front panel power button or the appropriate SCPI command.
MXG's installed in rack systems and powered down with the system rack power switch
rather than the MXG's front panel switch display a Error –310 due to the MXG not being
powered down correctly.
Secure mode automatically applies the selected Security Level action the next time the instrument’s
power cycles.
To Set the Level: Press File > More > Security > Security Level and choose from the following:
— None = factory preset, no user information is lost
— Erase = Erase All
— Overwrite = Erase and Overwrite All
— Sanitize = Erase and Sanitize All
To Activate: Press File > More > Security > Enter Secure Mode > Confirm
The softkey changes to Secure Mode Activated.
Securing a Nonfunctioning Instrument
If the instrument is not functioning and you are unable to use the security functions, you must
physically remove the processor board and, for vector instruments, the A4 Memory Chip from the
instrument. Once these assemblies are removed, choose one of the following options:
• Discard the board (or boards) and send the instrument to a repair facility. A new board (or
boards) will be installed and the instrument will be repaired and calibrated. If the instrument is
still under warranty, you will not be charged for new boards.
