That data represents a beat note between two optical frequencies: Nd:YAG laser stabilized to hyperfine transitions of molecular iodine and optical frequency comb that is phase locked to the SRS FS-725 rubidium standard. And it seems that AVAR of this measurement is lower than values for FS-725;
Which values of the FS-725 are you referring to?
I'm pretty sure the FS-725 has a PRS10 Rb in it. If so, have a quick look at these PRS10 performance plots: http://www.leapsecond.com/museum/prs10/ In particular, the ADEV of your data (pomiar61-frep.txt) which I attached in a previous posting (pomiar61-adev.gif) looks almost exactly like the ADEV of the PRS10 that I measured: http://www.leapsecond.com/museum/prs10/1sigma2.gif /tvb _______________________________________________ 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.
