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?

(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 .. $120. Apparently there is a PLL inside... the text string has a "PLL unlock" flag. There is no info on how it works and I have not opened mine up. I did a simple noise test on one where the input and ref clocks were from a Tbolt. It looks like the measurement noise is around +/- 0.0002 Hz. Lady Heather can now read it. Attached is a screen capture of the noise test. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
