a.To ensure that this newly installed option is functioning properly, the procedure that follows includes the
requirement of performing certain adjustments and performance verification tests. However, the completion of
these tests does not guarantee that the instrument meets all advertised specifications.
Software and test equipment is required for making adjustments and for performance verification testing.
Information on how to obtain this software can be found at:
www.keysight.com/find/calibrationsoftware
While Keysight does recommend that a full calibration be performed after the installation of this upgrade, the
end user must ultimately determine whether they want this service or not. If a full calibration is required,
arrangements regarding the level of calibration must be made between the end user and the calibration
provider.
