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

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).

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

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

Thank you for pointing that out. Most helpful.

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. ;)

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

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
