Do you have the schematic for this online somewhere? what is the range of the interpolator? which TIC is the red/blue points? the blue data looks like it is aliased somehow, perhaps a number that is truncated/rounded badly? On Sat, Mar 8, 2014 at 9:46 PM, Bob Stewart b...@evoria.net wrote: I

[time-nuts] New TIC test run

I put my TIC to hardware, and have started testing it.  Here is a sample run comparing it against the 5334B with an off frequency OCXO.  I've scaled and rotated to tried to cancel out the length of the cables to the 5334B.  Still early days with it, yet.
