^ +1  That and the matching signal generator are works of art, not mere electronics.

I feel so inadequate after reading this thread, 1 scope and 2 multimeters (not counting the half dozen free HF ones I use on model railroad stuff).
I keep looking for a decent 20MHz or so Tek analog scope for a decent price, mostly just to have a quality analog scope.

It's OK, rrinker. I only have two scopes, an analog and a digital, and the analog one needs work. So, effectively, I have one.

On the other hand, I have 11 multimeters at the moment. Oy! Gotta start a separate thread. :-DMM

 I suppose it is some consolation that I am considering purchasing another multimeter....

20 oscilloscopes?  Well you see I can't afford a really high end scope, so I figure that I can simulate one with a bunch of cheap scopes. 

I find that if I hook up my twenty 50MHz scopes in parallel that I can divide the incoming signal among them for an effective aggregate bandwidth of 1GHZ.  And since some of them are two-channel and some are four-channel scopes, if I hook them all in parallel I can get an aggregate bandwidth of more than 2.4GHz which is enough to troubleshoot WiFi routers and microwave ovens.

Or if I hook all the inputs in series I can either use them to handle higher input voltages, such as those generated by my Tesla coil, or get ultra-high resolution on very weak signals.  Why I can even peer into the nanovolt signal range to monitor the heartbeats of amoebas under my microscope.  Pretty cool!

Of course it's kind of awkward having a waveform split across all those displays, but sometimes you just gotta do with what you can afford.  Amirite?

Bill, you forgot to set them up in a grid for more visual real estate.

But really that's pretty much how the 100GHz scope from LeCroy works. Its 4 really fast scopes put together, each one of them built from 4 interleaved ADCs that are in itself built from interleaved ADC blocks internally.

Well I don't quite have 20... yet.   I do have 9 Teks and also intend to add a Rigol DS1054Z within the next two weeks.  There's also a possibility that I will be getting my hands on a Tek 561A.

Inventory:
(1) Tek 454A
(2) Tek 465
(2) Tek 468
(3) Tek 485
(1) Tek 7613

Don't worry. Once you've got one, the next few come along to join them. Pretty soon you're wondering if you should stop (no, of course you shouldn't).

Hi

I didn't realize we had to be able to *count* them all .... yikes ...

465's at least two
475's at least two
2465's more than four
2465A's more than four
2467B's at lest three working, about a dozen total.
7xxx series, had a dozen or so, sold them to a kid for next to nothing
probably another 5 or 10 that I'm unable to spot

Do we have to count the digital scopes as well? This is getting tiring ....

 Me too!  haha out of the 9 non-working there has to be enough parts to get 2 or 3 working ones!

Have you considered hooking them up anti-parallel?

That would just result in one giant flat line across all the displays as the waveforms all cancel each other out.

If I had 20 scopes I'd be very tempted to so something like this. 



And then I would would be drawn and quartered.

As a quick followup.

Anyone with 20 scopes, video camera, youtube account and enough room to do some oscilloscope dominoes?

In my defense, they would not be my oscilloscopes, so I can enjoy the event without risk. I can't ask Dave because it could be career ending.

It would work with multimeters (dominoes) but there is no real danger there.

Take a new Fluke DMM and and a new Rigol ds1054z drop off a roof. Set up a poll, the lowest count item get's to live. Will it be the Fluke or the Rigol? If it's a tie they both go.

Then just drop the fluke since it would just bounce anyway.

Especially when one (this one) is nowhere near 20, yet.  ;D Also registered.

(Of course, Daniel, anytime you need more space, I'm happy to adopt a scope or three.)
