I would not use a Thunderbolt. It dithers the OCXO frequency to correct the second pulse and that frequency change will be multiplied particularly in U wave applications.. I have never checked, but if LH has a hold function you could use it, but in that case I would also bring out the OCXO direct and amplify external if you plan on using it 1 GHz and above, if so contact me off list Bert Kehren In a message dated 6/3/2012 5:59:35 P.M.

You have all been a great help, thank you very much indeed, I doubt I will become as obsessive with accuracy as some of you apparently are, but it's good to know that such a friendly and sharing group of experts exists in one locale! 03/06/2012 22:50 -- Best Regards, Chris Wilson. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
