Do the mmW EXA specifications match the to-be-discontinued 856x series analyzer in terms of DANL and phase noise?

The displayed average noise level specifications on the standard mmW EXA are better than the 856x.  Additionally, since the mmW EXA's offer an internal preamplifier option (N9010A-P32 or N9010A-P44) that the 856x did not offer, the displayed average noise level specifications on the mmW EXA's with the internal preamplifier enabled and turned on are even better. 

The mmW EXA's phase noise performance is not as good as that of the 856x series analyzer.  Both the phase noise and DANL specifications can be compared in the following data sheets.
