[time-nuts] Recommended parameters for Timelab ADEV analysis

[Edgardo Molina]

Dear Group,

Now that I have setup TimeLab along with the Prologix GPIB to USB adapter and the HP-53132A frecuency counter, I am starting to get some data from my frequency standards. Still I think I have a long way to go in front of me.

One of the main concerns that cross my mind at this point are:

a. What is the recommended sampling duration to consider for Quartz, Rubidium  and other types of oscillators?
b. What are the recommended sampling intervals for the above mentioned oscillator types?
c. I am using a 10 MHz Rb FE-5806A frequency standard as an external reference for the HP-53132A. 
d. I am connecting my DUT at the frequency counter channel 1
e. I am setting Timelab for Data Type = Frequency
f. My graphs somehow have the same geometry of classical ADEV examples, I can differentiate the ADEV noise types quite easily.
g. Should I use sub-second sampling intervals for my graphs to start closer to the vertical axis of the graph? Or should I use a conservative 1s sampling rate?

With the previous questions I am looking for consistency in my ADEV studies. Are there any typical ADEV conditions to be considered when analysing this way?
Am I missing something? My apologies to everybody if I am missing something or doing it the wrong way. In the end I want to learn more than anything else.

Your kind comments are welcome. Thank you.

Best regards,
