Compact assembly workstation

I use it now and then, when I'm working on analog things; it's really a fabulous instrument. It's not much help in designing picosecond-speed 50-ohm stuff.

But I agree, it is beautiful.

I forgot to ask, what kind of connector is on those? Why wasn't a BNC good enough?

It's an SO-239 'UHF' connector, which predates BNC by 20 years or so. My 610C has a nice Teflon UHF M - BNC F living on it.

(The 610C is from '68, when UHF connectors were still common outside ham gear, I believe.)

I have no idea how old this one is

but it probably pre-dates most of my employees and most of my kids.

It still works fine, but fast mode is goofy. At extreme limits, it gets very slow.

And the 10-fA FS range (1E-11A on the big dial, 0.001 on the small one) is purely aspirational.

OTOH when full scale is 62000 electrons/s, keeping both decent knob response and low noise is a bit of a challenge when you're building all-discrete circuitry even today. ;)

We have 2, they are ok. You need to mask off the light, to prevent glare. It doesn't exactly shine onto the work surface.
