Hi Filip, See attached. Let me know how your results differ from this.
It looks like 1.75 hours of frequency data of a 250 MHz DUT. You first convert your raw frequency measurement data into normalized frequency error data (i.e., subtract and divide by f0 = ~250 009 770 Hz). You can run the y- form (frequency) of an adev calculation directly, or integrate the frequency error series into a time error series and run the x- form (phase) of adev calculation. I can explain more if you wish. JohnM and UlrichB can double check this plot with their tools. /tvb----- Original Message ----- From: "Filip Ozimek" <me_su...@o2.pl>

I'm trying to calculate AVAR from collected data, but I would expect a different behavior of my DUT. Does anybody can calculate the AVAR for me?Gate time was 1s, without any deadtime between measurements, this is a file http://www.fuw.edu.pl/~fozimek/pomiar61-frep.txt with collected data. Thanks, Filip Ozimek
