HP 5257A transfer oscillator sampler 18GHz for counter 1971

This Hewlett Packard plug in module model 5257A is for HP 5245L counters specially modufied to run this unit. Opperation : under sampling a very high input frequency with a much lower variable frequency to get out a low frequency to check if beating and then count the harmonics times your known input frequency is a rather smart way to make a "cheap" and much more simple way to measure frequency all the way up to 18GHz, design released about 1971 my unit is from about 1982, last calibrated 1990. when you are done with this video, PLEASE try scroll thru my other videos here    / @teardownoz2cpu   -- #repair #hewlettpackard #teardown --- I use auto generated subs, i am sorry there are a few spelling errors, maybe one day they can do it better.. -- (Thanks to all my Sponsors / Traders / Swappers / Sellers / Buyers, without your support and constant flow of cool items in/out, none of this would be possible)
