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

instrument’s power is cycled.
