Скачать или смотреть New (to me) FE-5680A Rb @ 10MHz

This is a phase comparison between an FE-5680A Rubidium oscillator and a CMAC STP-2390C at 10MHz. The phase is triggered on the CMAC to improve the trigger clarity and to assure minimal jitter that will occur during the measurement due to amplitude noise. The CMAC is an SC-cut crystal oscillator that was tuned ahead of time to match the frequency of the Rb. At this point, I am not aware of how accurate the frequency is but I am seeing how stable the oscillation of the Rb is against a known good OCXO. To me, this looks good. There is a phase offset that can be see that is very slow. When I took these pictures, the camera battery died and I was not able to continue but the clarity of the phase continued to look good.
