   Oggetto [time-nuts] HP 5065A A1 replacement with DDS
   Hi,

   My purpose was to provide an inexpensive (<$30.00) and simple way to
   replace a defective A1 without degrading the performance the original A1
   gave.
   The Chinese DDS allows this without having to solder all those tiny pins!
   Both actually performed better than the original, and the same in
   a "super" mod unit.
   I was not claiming "theoretical" perfect performance and rejected more
   complex schemes purpose.
   Also the current drawn by the A1 is part of the current budget for the
   TED so an A1 replacements current draw should be between 100 and 150 mA!

   Cheers,

   Corby
