<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>

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.

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>
