1911A_12A 50MHz reference output

During the performance test of these meters, the reference output is compared against a more accurately calibrated standard reference.  What is the accuracy/uncertainty of this standard reference output?  Also, does Agilent provide the output SWR data on the standard reference output?  How does this method compare in terms of accuracy to the more traditional method of using a 432A and a 478A-H76?
