The measurements were made with an upgraded 5061A (Datum tube and 10811-60109). I have used it to measure my GPS clock at 2.0E-12 at t=100s before, so it's actually inside the 5071A limit there. I don't know where its floor really is but it appears to be much better than spec (as are most 5071As, presumably). -- john, KE5FX _______________________________________________ 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.
