The GPS10RB incorporates an atomic rubidium oscillator as the main frequency reference, but is priced comparable to crystal-based units. The advantage of rubidium is better stability, especially if the GPS signal is lost. A rubidium oscillator has a drift rate that is typically 30 times better than the best quartz oscillators available today.

Recently there was a discussion of cheap GPSs and cleaning up their output to make a lab quality precision 10 MHz frequency standard.. I have those references. Basically I just want to ask if there is any standout way to go from a GPS 1PPS with the typical issues to a low jitter 10 MHz signal in people's opinion.

The GPS10R is normally operated with the Rubidium oscillator's 10 MHz output, locked to the GPS satellite system. In the event of a failure of the GPS signal for any reason, the GPS10R will automatically switch over to free run mode. In this mode, the GPS10R's Rubidium Oscillator still achieves Stratum 1 performance over a 72 hour period.

As a 10 MHz reference for microwave transverters, I've found the "barefoot" FE-5680A to be unsuitable for microwave transverters due to low-level audio-frequency phase modulation on the output. To use the FE-5680A with a microwave transverter it is necessary to "clean up" its output by locking another crystal oscillator to it as described below.

As long as there is a valid satellite signal, the internal local oscillator is monitored and adjusted and the mean 24-hour frequency offset is always virtually zero. However, in this mode, the inherent short-to-medium term stability of all local oscillators, except rubidium, is compromised. This is true for all GPS frequency references.
