I need some guidance from the collective. I just finished rebuilding my PRS10 lab standard and it is now using a M12+T GPS module. I have completed my site survey and it is now in "hold position mode", TRAIM is enabled with 500ns alarm setting and the 1PPS is enabled during non-TRAIM alarm conditions.
The PRS10 is set for default 1PPS steering, but all of the other parameters are just as I received the unit 5 years ago. My questions are these; 1.) Should I reset the PRS10 to its Default settings or just adjust selected parameters to align the unit for proper operation with the M12+T unit? And if that is the case, what parameters need adjusting? 2.) Are there any special settings, other than what WinOncore sets, that I should make to the M12+T unit? 3.) After all this is completed, how do I know that the PRS10 is properly tracking GPS and maintaining frequency accurately? I don't have a Cesium reference, but I do have an un-disiplined LPRO-101, but I don't think that really helps me determine frequency accuracy. I will be adding the sawtooth correction eventually to the M12+T 1PPS output, but observed negative sawtooth with WinOncore shows +/- 14ns changes with some bridging occasionally. While I don't ever want to claim NIST traceability, I would like to be a close as possible, and I guess that is the bottom line need here. So what else do I need to do to get as close as possible? Thanks for any help.
