Hi Anders, thank you for providing your graphics. Very interesting. I will put my results to my github repository if done.  Right now I have to take a break for my surgery. best regards Chris --- 'Everything should be made as simple as possible, but not simpler.' -- Albert Einstein Am

Hi Assuming Mark’s data is at 10 MHz and 1 second then 0.0002 Hz is 20 ppt. That number can be compared directly against data presented for a variety of other devices. By far the best way to do the comparison would be to take data over a range of tau’s and look at the resulting plot. That way

This would be an interesting compare. I want to compare the FA1 and the TSA3011 if I am back in office and have both in my hands... But I really do not want to buy unnecessary tools...  So if someone has done this it would be nice to read about that. Mark, do you have also a TICC? best

How would this compare to the TAPR TICC Rev D? The one that has the arduino base? About half the price I see. Regards, Jerry > On Sep 2, 2019, at 5:50 AM, Christoph Kopetzky wrote: > > Hi Mark, > > interesting post. > So is the FA1 compatible with the TimeLab or Stable32 software? > And

Yes, it should work with Timelab, Stable32, etc. It streams a series of frequency measurements every second out the USB port (it uses a FTDI chip for the USB interface). The data is of the format: " F:0123456789.123456789" (without the quotes) Measurements with a PLL unlock error are

Hi Mark, interesting post. So is the FA1 compatible with the TimeLab or Stable32 software? And could I do phase noise measurements with it like the TimePod? Chris Am 30.08.2019 um 22:57 schrieb Mark Sims: (Hopefully this is not a duplicate post... hotmail has been having issues) The FA1 is

maybe the measurement principle is similar to the PicoPak? http://www.stable32.com/PicoPak%20App%20Notes%20Links.htm Do open it up! And send a high resolution picture to the ist ;) A. On Sat, Aug 31, 2019 at 1:11 AM Mark Sims wrote: > (Hopefully this is not a duplicate post... hotmail has

(Hopefully this is not a duplicate post... hotmail has been having issues) The FA1 is a small, USB powered frequency counter. You supply it with a 10 MHz reference and an input frequency of 1 .. 80 MHz. It outputs a text string of the measured frequency every second. They cost around $80
