Hello,
Can anyone recommend software to calulate the Allan varaince from a set
of data?
I have taken many measurements with the SR620 using it's 500 second gate
and downloaded the results into Excel.
I can use the SR620 itself to calulate the Allan Variance. However, I
want to know the Allan Varaince over a 10000 second sample instead of
500 seconds.
Hoping to plug the data into software and get the result!!
John Miles has written some nice software.

It is intended to do the measurement direct, so the measurement log
becomes in the right format.
Cheers,
Magnus
