Longest desktop instruments (in a home lab)?

(1/7) > >>

Faranight:
Hey, a bit of an odd question, but what is the maximum instrument depth that one can expect to have in a home lab? I'm currently trying to dimension some workbench shelving for my instruments, and I'm having trouble deciding how much space to reserve. I already have a number of lab instruments (PSU's, scopes, DMM's, freq gens, a programmable load, etc), and my current longest instrument is the DMM6500 at about 400 mm plus some space for cabling in the back. I already made the mistake of going for 300 mm shelving, but that was before I got the DMM6500 and I had to plan a redesign. I'm not a professional electronics person, but I do love electronics as a hobby very much, and I see myself getting a desktop VNA, a frequency counter and maybe some other instruments in the future.

Is 400 mm deep shelving a reasonable choice?
If you have a desktop (not a rack) instrument that is longer than 400 mm, which one is it and how long is it?

nctnico:
40cm is minimum; most equipment will fit on a 40cm shelve but also make sure to get a couple of meters of 50cm shelve to store larger (older) equipment. That should get you going for 99% of the equipment. I do have a large DC load which measures 65+ cm but that just sits on top of a storage trolley by lack of a better space.

factory:
I've got several HP scopes that are approx 2ft in depth, one of them is solid state (except the CRT), perhaps some Tek scopes were longer.  :-// The longest one is kept on top of a filing cabinet.

I have a couple that are 410 mm deep excluding knobs. But don't forget the mains power connector/cable, which can add 50 mm (depending on type).

You can buy right-angle adapters for them but even so it's something you need to take into account.

nb. Many devices have things right next to the power socket which means you might need right-angle adapters that go upwards.

(eg. Fuse holders, power switches, other connectors...)
