Hi You have a lot of stuff that runs off of GPS L1. Any “common mode” issues (like ionospheric disturbances) will propagate into all of them. What impact that has on each one is very much a “that depends” sort of thing. The firmware and filtering quickly get into the act …. They all will wander, just not in exactly the same way.
The PRS-10 does have an internal “sync” capability. The main purpose for the input is to simply calibrate the device from time to time. It is not really intended to replace a GPSDO. Any of the devices you have are fine for putting the PRS-10 on frequency to calibrate it. All are equally likely to wander around. The PRS-10 will not help much with this wandering. You can look at all of this with something like a TAPR TICC. To look at lots of them at once, a set of TAPR TICC’s would be nice to have …..
