[time-nuts] Question about effect of sample interval on ADEV

[Robert Darby]

John,

After a night's sleep and a rereading of  your post I finally realized 
what I was doing wrong.  I did not understand the the role of the 
sampling interval setting and the display rate setting on the 5370.  
When I follow the process below the results are totally consistent.

Sorry to taken your time and thanks all for your help.  Now to find the 
original issue.....
