  • Rubidium vs. GPSDO 10Mhz oscillator - Page 1

    Re: Rubidium vs. GPSDO 10Mhz oscillator. It depends on what you need this for. If you truely need a calibrated source, a GPSDO is the only solution for you. It is pretty unpractical though, because it takes relatively long to lock, and you need the antenna setup as you mentioned, but its uncertainty is defined.
