Hi Tom,
 
The plot from the brochure that you are looking at is one you had measured  
for us on the FireFox GPSDO predecessor, which did not have Temperature or 
aging  compensation, and had a much coarser TIM, DAC, and DAC reference etc but 
used  the same OCXO as the Fury. The Fury improves upon this previous  product 
very significantly. We are still preparing the ADEV plot of the  final Fury 
using a Cs standard.
 
According to Symmetricom, the performance of the 58503b between 100s and  
1000s is about 3E-011 typ and 5E-011 max. according to page 3 of this  
Symmetricom datasheet:
 
_http://www.symmttm.com/pdf/Gps/ds_58503b.pdf_ 
(http://www.symmttm.com/pdf/Gps/ds_58503b.pdf)  
 
Our spec is typical, and measures about <5E-012  on the PDF ADEV plot. That 
is almost an order of magnitude better than  the Symmetricom datasheet for 100s 
to 1000s. Of course as you mentioned  every oscillator is different, and 
improves over time just as red  wine :)
 
Also, our phase noise is about 10dB (or more) better, while our power is  
almost an order of magnitude lower than the 58503b.
 
Our price is also about $3000 less I believe.
 
bye,
Said
