These are 4-BYTE single precision floating point numbers, not 4 bit integers. They are the values plotted in the Lady Heather PPS and OSC graphs (and used in the "ADEV" calculations and plots (not actually true ADEV values since they are not refereneced to an external reference, but still useful).

A good Tbolt >implementation can get the PPS plot to under a few nanoseconds of error. -------------------------- Each is a 4-bit signed integer with units of nanoseconds for PPSOset and in pars per billion for 10MHZOset. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
