Re: [time-nuts] Noob question on measuring Allan Deviation on 10 MHz source

John, I believe the scaling factor was the key. Thanks. I have v 1.58 of Stable32 and the scaling function now has its own button and is not in the Open dialog. I'm sure I'm nowhere near out of the woods yet, so I'm gonna keep your e-mail addy on speed dial ;-) geo On Wed, Dec 14, 2011 at

[time-nuts] Noob question on measuring Allan Deviation on 10 MHz source

List; OK, I need to measure the stability of a 10 MHz sine-wave source. After reading a lot of background info on this list and some of the sources that were referenced, I thought I could get away with a frequency measurement. I now think I was wrong. What I have is an Agilent 53230A counter (a

Once you get the frequencies matched with a fraction of 1 Hz, I would measure the phase between the 10 MHz source and the 10 MHz from the Trimble. On 12/14/2011 12:29 PM, George Dubovsky wrote: List; OK, I need to measure the stability of a 10 MHz sine-wave source. After reading a lot of

Hi George -- You can feed frequency data into Stable32, but the documentation doesn't clearly explain that you need to scale the readings into fractional frequency using the scaling function in the File/Open dialog. To get fractional frequency, you divide the results by the nominal
