Basic Operation
Using Security Functions
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:
1. On the front panel, press: I/Q > I/Q Calibration > Revert to Default Cal Settings
2. Send these commands:
• :CAL:IQ:DEF
• :CAL:WBIQ:DEF
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
CAUTION Do not use the functions Erase, Overwrite, or Sanitize with signal generator firmware
revisions C.04.84, C.04.86, or C.04.95. If you have one of these revisions installed, please
upgrade immediately to revision C.04.96 or later.
1. 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; 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.
Press Utility > Memory Catalog > More (1 of 2) > Security > Enter Secure Mode > Confirm.
