This precious thing allows me to connect my GPSDO and have very stable 10MHz output, so all test equipment can use it as reference. The GPSDO itself provides very stable frequency, but has “only” an OCXO inside. So, long-time stability comes from GPS, but now short-time stablility also comes from the rubidium standard and not from the OCXO anymore. So more long- and short-time stability!

This is how the old good Tektronix TDS380 acquires a 500MHz signal from Marconi Instruments 2031 signal generator. Very stable, calm trigger and display. No jumping around, albeit using 16x averaging.
