Reposted with a proper title: I am only really familiar with the 5650A/5680A with the AD9830A DDS chip that responds to the ASCII "S/E/F" commands. This manual talks about a 5680A with a different set of commands:

Rex and myself bought units that were not programmable. Both of us have tweaked the pots and have not seen any change in drift. I turned pots 1 turn per day and did phase observations, over the course of a week. They guy that sold these units on ebay claimed they were programmable but could not produce the information. Its been noted he has changed his ebay user name about every 6 months (that might give you an idea about his operation - he also complained about whiny time-nuts postings about his operation). _________________________________________________________________ Be the filmmaker you always wanted to be—learn how to burn a DVD with Windows®. http://clk.atdmt.com/MRT/go/108588797/direct/01/ _______________________________________________ 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.
