<p>They make pretty pictures lol </p><p>They measure voltage basically. Think a multimeter. But really really really fast. Lets you analyze and capture electrical signals in real time.</p>

 

<p>holy **** i had no idea that much bandwidth cost that much money. the time/division menu driven display&nbsp;on those scopes would probably be alien to me.</p>

 

<p></p><p>&nbsp;</p><p>more accurately, they measure voltage over time and display it graphically on a cartesian coordinate plane.</p>

 

<p>*****? All digital. When I get mine up and running I'll show you. I only have prototype ones right now that I can't share.</p>

 

<p></p><p>Not just caresian coordinate </p>

<p></p><p>&nbsp;</p><p>i can only imagine the fun involved with designing the PCBs alone for those things.</p><p>&nbsp;</p><p>&quot;dammit fred, that trace has 0.00000000000001 pF and gives us a 3db rolloff at 33Ghz. start over.&quot;</p>

 

<p></p><p>&nbsp;</p><p>it was a joke, see ninja edit</p>

 

<p>Lol. Not my department. I just turn the hardware on.</p>

 

The best oven I could buy for my bakery is literally the cheapest Oscilloscope cost....that is stupid expensive.

 

<p></p><p>&nbsp;</p><p>thats why i rock a used one of these (from the 80s?), which still go for well over $100 on ebay if its in good shape</p><p><img src="http://cimg0.ibsrv.net/gimg/www.miataturbo.net-vbulletin/1050x788/80-tektronix465_864f35b3c5a37cce880f0f6e96fa886e99faa dc0.jpg" title="" /><br /><br />&nbsp;</p>

Digital scopes are significantly more useful than analog ones, IMHO. They've also gotten pretty cheap on the low end -- a Rigol 1052 is a 2-channel 50Mhz DSO and runs $300 brand new. 50Mhz may be low by gigabit ethernet standards, but it's still about 3 orders of magnitude more speed than you'll need to look at any signal in a Miata.

<p>The one I link is the one I have if it wasn't clear </p>

 

Explain it to me like I'm 6.

What is the 300k one used for. What needs such precise measurement of the rate/flow of electricity. I can probably think of a couple very narrow applicable fields like MRI machines or Cat-scans but what are they primarily used for that people are buying them in quantities that 300k is "fair".

 

<p>Anything and everything &quot;high speed.&quot; Especially high speed busses, and internal communication lines. Companies like intel buys them by the $million.&nbsp;</p>

 

<p>Also, money buys you speed more than precision. Most of them are very precise. But spend a lot and you get really fast, really capable, and able to do lots of analysis and stuff in real time.</p>
