Hello Scott, that's great news! A Phase correction of 0.5 means the unit will only try to correct for long-term UTC offsets with very little "force" on the Rb, and it may take quite a long time to get the phase error to 0ns. But once you are around 0ns as in your case, the Rb is so good that it won't need much of "convincing" (read: error correction via EFC voltage changes) by the Fury to stay on phase/frequency. Also, if it keeps it locked well, then you may try to increase the EFC Damping to say 80 - 120 to reduce the control noise further. This increases loop phase-lag, so if overdone then the loop may start to become unstable. Said In a message dated 4/7/2008 07:06:00 Pacific Daylight Time, [EMAIL PROTECTED] writes:
atom FRS-A DAC GAIN: 5000.00 EFC SCALE: 0.50 EFC DAMPING: 25 OCXO SLOPE: POSITIVE PHASE CORRECTION: 0.500000 I think the FRS-A is adjustable from +-1.2e-9. So far it seems to keep it within +-3ns from GPS. Scott **************Planning your summer road trip? Check out AOL Travel Guides.
