Hugh, What year is your photo from? Here's a similar, but older photo of hp's house standard:
http://leapsecond.com/history/Benchmark.htm This was from roughly 1966 (note the dual hp 5060A). The HPJ issue containing that article is here: http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1966-08.pdf The house standard is featured on page 20, but there's also a glimpse of it on the top of page 15. /tvb ----- Original Message ----- From: "Rice, Hugh (IPH Writing Systems)" <[email protected]> To: <[email protected]> Sent: Friday, January 04, 2019 4:07 PM Subject: [time-nuts] Part 2: Atomic Clocks: It is important that they keep good time. HP's Santa Clara Division (SCD), in addition to building the Cesium Beam Frequency Standard Atomic Clocks, was an official time-keeper for the U.S. Naval Observatory, maintaining the west coast reference for Coordinated Universal Time. This was done in our standards lab where we kept a rack of several HP Cesium standards. Hopefully the attached picture of the lab comes through for some of you. ... _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
