[time-nuts] SR620 software and adjustment

[Eric Garner]

Volker:

This is the adjustment procedure that I used:

Use the following adjustment sequence to get the frequency spot on:

1. Set the Cal jumper to Cal Enable
2. Connect the reference to Ext Ref (rear) and Input A
3. Switch the counter to Ext Ref
4. Set the CalByte 50 for the best display (this is a very fine adjustement)
5. Switch the counter to Int Ref
6. Set the CalByte 4 for the best display (this adjustement is coarse,
optimize!)
7. Set the Cal jumper to Cal Disable


The procedure can be found in the list archives and at Brooke Clarke's
website at: http://www.prc68.com/I/TandFTE.shtml
