Uncertainty specification for Scd21 on the ENA5071C

I am trying to determine the uncertainty specification for differential S parameters on the ENA 5071C. My machine has options 485 and 790. In particular I am concerned about a measurement  of Scd21 which of necessity employs the Fixture Simulator and internal matrix math for four
of the two port parameters: S31,S32,S41, and S42. I would expect Agilent
to derive and publish the uncertainty values for all such four port differential parameter measurements to assist customers in making
meaningful measurements and being able to publish accurate results.
