After purchasing an N9094AK upgrade, must the instrument be sent to a Keysight Service Center to be upgraded?

There is no need to send your instrument into a Keysight Service Center for one of these upgrades to be installed. All of these upgrades come pre-programmed and ready to be installed by an Advanced User. However, if you would prefer a factory trained technician at a Keysight Service Center performs the installation that is always an option for you.

See the attached installation notes for detailed instructions on what these upgrades involve.
