Hmmm ... can you say more about this current source error signal? I've been thinking of locking my Rb standard to GPS. I was simply going to use the same circuit (1 pps, 10 MHz in; analog EFC voltage out) that I have running with my OXCO but with different filter and EFC DAC coefficients. So is this not sufficient to phase lock GPS to a Rb standard?
