Richard, This paper is fascinating to me. I finally understand how the TMDE/Metrology lab to which I continually sent my measurement equipment for calibration was so important.
Looking back, I recall something that looked exactly like an FMS rack shown in the paper! It was accompanied by a make-shift cubicle with walls of HP and Marconi gear in various states... and a sweet, aged, bearded geek with trifocals... It's telling, I think, that the first FMS was built on an Apple II. -CH Chris Hoffman cq.k...@gmail.com http://ar.ctur.us On Jul 18, 2012, at 7:00 PM, Richard H McCorkle wrote: > Chris, > If you have multiple standards to monitor (or may have in the future) > you might consider building a small version of the NIST FMAS board > described in http://tf.nist.gov/general/pdf/1950.pdf to keep track > of them. > > Richard > > >> What advice does anyone have on building/finding cheap [visual?] comparison >> devices >> to display or detect a timing [lesajo?] from my 10MHz sine wave ports? >> >> Further, what timing/health metrics could/should I be aware of and/or >> looking for? >> >> I do not want to spend good money on another oscillicope if I can help it, >> but I do >> want to see, or at least be remotely aware of clock slips/walks and other >> anomalies.
