    It's just Simon and me in our shop, and it's walking distance from my
    house, so when I rented the place (11 years ago now), we moved my home
    lab there and have continued to improve it. One of these times when we
    have a quiet few days to re-organize, I'll redo the lab tour, but here's
    the old one

    <https://electrooptical.net/lab-tour/>

    Some of the pictures are a bit dark, because they were taken with the
    camera still set to 2 stops underexposure (it's mostly used for doing
    scope shots and stuff).

    Cheers

    I see a very handsome digital delay generator. And roughly four
    Boonton c-meters.

    Is that my old 11801? "Free to a good home."

    Yup, with the now-unobtainium VF display, just for that certain
    something. We used it most of last week, working on our balky lidar
    chip. That let us prove that the issue had nothing to do with the
    trigger vs. enable timing, which was a help. I generated the rest of
    the timing with a 74HC40103 8-bit counter and a 74HC86 for buffering and
    optional-inverting.

    And roughly four Boonton c-meters.

    One of them is an RF millivoltmeter, but there's another 72C cap meter
    under the bench in the back. Can never have too many. ;)


    Is that my old 11801? "Free to a good home."

    It's your old 11802, which is still put to good use, and another 11801C,
    plus about 20 plugins and a couple of the 2-m extender cables to allow
    the sampling heads to sit on the bench right by the gizmo under test.

    Then there's a TDS 694C (10 GSa/s simultaneously on 4 channels, 3 GHz
    BW), two TDS 784As that started life as 744As, and so on and so forth.
    A reasonably up-to-date list is at

    <https://electrooptical.net/capability/equipment/>,

    and a one-pager for Photonics West last February is at

    <https://electrooptical.net/static/media/uploads/eoionepager.pdf>.

    We've revamped our product line--I'll post the new HEO page when it's
    ready. (Right now it just redirects to EOI.) We think it's pretty
    striking, and in the process we nailed our EMC problems to the floor.

    Cheers

    Thank you for pointing that out. Most helpful.

    As of my latest update the main pieces I have are:

    Rigol 1102E 100 MHz DSO

    Kikusui COS560A 60 MHz analog scope

    HP 3478A bench DMM

    HP 5334B counter w/ OCXO & 1.2 GHz channel C option

    Siglent SDG1032X arbitrary waveform gen

    GPS-disciplined 10 MHz reference oscillator

    Agilent E3631A triple-output PSU

    Assorted switching PSUs

    Amprobe LCR55A LCR meter & Amprobe AM-220 handheld DMM

    HP 8012B pulse generator

    Quick 957DW+ Hot Air Station:

    <https://www.amazon.com/gp/product/B074SBH4G5/>

    2x Radio Shack 60W digital soldering stations
    (Designed and manufactured in Taiwan for Radio Shack, a nice iron):

    <https://www.radioshack.com/products/60w-digital-soldering-station>

    A couple other weird pieces like a Heathkit vacuum tube capacitor
    checker and NanoVNA portable VNA that don't get a lot of use. I don't do
    much RF (50 MHz+) work at the moment
