Confirm Sanitize.

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 front panel, press: Utility > Power On/Preset > Restore System Defaults > Confirm Restore Sys Defaults

•Or send the command: :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:

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

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.	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
