Curious also that 9.99998278 +.00001722 = 10.000000000 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jim Robbins Sent: 06 June 2008 14:02 To: [email protected] Subject: [time-nuts] Measuring Rubidium frequencies
Hi all, I have a problem which I am unable to understand and need some help. I have two M100 Rubidiums, a Racal 1992 counter, a factory standard T'Bolt and a Symmetricom Starloc II. When I set up either GPSDO as the External Timebase for the 1992 and measure either Rubidium, I get the same reading of 9.99998278. When I use the 1992's Internal Timebase, I get 9.99999995. All equipment has warmed up. The antenna is a Symmetricom HP 58532A on the roof. On a few occasions I have seen the frequency drift up to 0.00001722. I would have expected that both Rubies would have read 0.00000000. Any ideas would be much appreciated. many thanks, Jim Robbins _______________________________________________ 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. _______________________________________________ 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.
