To control the instrument remotely using a Web browser, you first need to log in. Login sessions are valid for 100 days, until the password is changed, or until manually logged out.

The default password is "Keysight". It is recommended to change this as early as possible.

This remote browser password is separate from the Windows password on the instrument.

The password can be changed from any logged in remote browser, or directly from the instrument’s front panel in the Settings menu, under Preferences.

Changing the password manually or via Restore System Settings will log out all existing Web UI remote browser sessions .

Password requirements:

Preset

 Password is unaffected by Preset but is set to "Keysight" with Restore System Settings to Defaults.

State Saved

Persistent, survives preset and power cycle but not saved in the instrument state.
