[time-nuts] Allan variance of Thunderbolt

[Patrick Reynaert]

Hello,

a question regarding the Allan Deviation of the Thunderbolt. 

the curve at
<http://www.leapsecond.com/pages/gpsdo/>
gives a deviation of 1.5e-12 at tau=1s

whereas from the Trimble datasheet:
<http://trl.trimble.com/docushare/dsweb/Get/Document-10015/> 
at tau=1s, the deviation is 9e-10  ... 

Is the data-sheet a worse-case scenario?

Regards,
Patrick
