Teardown, Analysis and Part-Salvage from an HP 70001A Series Optical Microwave Analyzer

In this episode Shahriar performs a teardown and analysis of several HP 70000A modules. The modules include a 20GHz optoelectronic converter, 2.9GHz tracking generator, 10MHz/100MHz precision reference and a 22GHz spectrum analyzer.

Along with the teardown of these modules several microwave components are recovered for future use including amplifiers, VGAs, mixers, photo detector and OCXOs. The 22GHz spectrum analyzer module is preserved since it is simply too beautiful to destroy.

    I bet you felt really guilty after dismantling that beautiful piece of equipment.
    You have to break a couple of eggs to make a cake though.
    Great teardown and thank you.

    I would be very interested in seeing characterization of the various modules that you salvaged from the 70001A, along with a discussion/tutorial of the characterization methods and techniques. While I was watching the original video, I was hoping we would get to see some of that. Alas, there was no time…

    Do you take offers for the RF section? 🙂

    Absolutely wonderful and instructive video, Shahriar! And your expertise in electronics is only exceeded by your artistic sense … a splendid choice to keep the last module fully intact. A unique and artful conversation piece, and a testament to mechanical and engineering design. And what great fun to watch you … like a child opening and endless supply of Christmas presents. Your excitement is infectious. Thank you!

    All the microwave plumbing is indeed a work of art! As usual, your videos are better than most $500/credit hour lectures. i wish i knew where that dumpster is located!

    This 70000 series in the teardown was in the 1992 catalog as lightwave analyser 71400C ,
    sold in a package for 101.000 US$ without VAT !
    which would be 167.000 in 2014 according to the inflation calculator ,
