My_Tuning_Constant


 

Hi!

How did you find the new tuning constant ?

The screen on my 49er reads 7.062.0 versus my frequency counter showing 7.061.8. I'm a bit stuck finding my new tuning constant.

The formula shows FOUT =(TW x CLKIN) / 4294967296

TW= (FOUT x 2^32) /125000000

TW = (
7061800 x 4294967296) / 125000000

TW = 242641600.4071424

This is were I get lost,?
242641600.4071424 = FOUT x 34.359738368 ?

I currently have the default? 34.35910479585483 as my tuning constant.

Any help on how to get my tuning constant or where I can learn more on this subject would be greatly appreciated.

Regards
Norbert
