[time-nuts] Ebay FE-5680A Rb: Are they that good?

[EWKehren at aol.com]

Pop the lid and look if it has the 60 MHz osc. or just connect the RS 232  
and it will tell you the settings, all units with date code 2003 are of the 
new  design with the DDS, the ones with variable frequency output you will 
not get  for $40

How does  one tell of the -5690A has 'Option 2', which is the ability to 
'tune' the  device via the RS-232 interface?

Is there a particular ebay seller with  the appropriate  units?
