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<cr><lf>" (without the quotes)
Measurements with a PLL unlock error are preceded by an '*'. I've only seen unlocks when changing the input freq from say 1 MHz to 10 MHz. I get two flagged measurements each time the freq changed. I don't know how small a freq change can cause an unlock. I don't know if Timelab can directly take the output data stream because of the leading "F:". You may need to capture data to a file and edit off the " F:" I also don't know how well it would work for phase noise measurements... it would be no where as good as a TimePod. I am doing some tests to see how well it compares to a TAPR TICC. BTW, my FA1 seems to have a frequency measurement bias of around -0.0002 Hz on a 10 MHz signal. Also, I don't see any temperature related variation in the measurements... air conditioning was swinging the room temp over a 2 degree C span and I saw no traces of it in the results. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
