[time-nuts] time-nuts Digest, Vol 49, Issue 83

[Mark Sims]

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:

Hopefully it will let you talk to your unit...

Mark, which pot is it ?

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).
