Not necessarily so..
My HP Z3815A here (desktop unit) has horrible phase noise and massive
spurs. Really to cry over since I know what the internal OCXO (1938A type) is
capable of generating.
See the attached plot.

So if I want a really souped-up freq standard for my lab, then I should
concentrate on finding the best oxco I can (which may be disciplined by
the
GPS or manually occasionally calibrated to GPS), and use the best power
supply I can find. These seem to be what I should concentrate on rather
than more channels.
I do believe that I read some stuff on the internet that the HP GPS DO's
do
seem to have very good power supplies (or converters) which contribute to
low spurs. So it seems the HP's do have a real advantage (not just the
name).
