An oscilloscope with a high enough frequency might be able to track Gov. Romney's changes in position about political issues.

^^^ Perfect example. Thanks.

Al,

To put it simply, an oscilloscope is a volt meter with a time component. The vertical axis is voltage and the horizontal is time.

The scope has range controls for both axis' similar to the x1, x10, x100 volt ranges on a regular volt meter. These allow you to visualize the wave form and compare it to the scale on the face of the screen to get a reading.

I bought a kit and built my own digital scope for analyzing the various ECU signals on my car.

Here's a video I shot of the rack control signal at idle:

Clk's Ebay Stuff BUY SOMETHING NOW!!!

I have only known one person to ever own one, but they told me the difference between an ignition analyzer and a O-scope was the markings on the dials.

An analyzer is set up to do one thing and do it really well: Analyze your ignition. He could see if all eight plugs were firing the same or if one was weak and what was causing the weakness.

You can do the same thing with an O-scope, but you have to know how to read it and how to set it up. The Analyzer should also come with all the connections you would need whereas a scope would just have a bunch of places to plug stuff in. You would have to figure out the stuff.

If you want to go nuts then look for an old Sun Tune-Up Scope. These things are of little use to shops today, and just because they cost $16,000 in 1980 doesn't mean they cost more than a few hundred today.

They take up a lot of room in your garage, but they do look really cool.

AL........

Check out this item on Ebay. I don't know how to post a link, but the item number is 230776218117. It is a giant Sun Analyzer and the asking price is $250.

You would have to drive to Chicago to pick it up. And bring a trailer!

You know, this really would look cool in your garage.
