Fun video from "Curious Marc" on driving a Soyuz digital clock with an HP cesium standard. For an encore he does some cool data collection and analysis using an HP-85.






(The clock uses an 800Hz 28v signal gated at 2PPS for an external reference - his earlier video sleuthing that out was pretty interesting as well.)
