[time-nuts] ok, newbie questions

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).
