Thanks for all the help guys, And Dave, the website you linked was very helpfull, Thanks again.

I'm sure you could find some theoretical stuff on it which would arm you with a good background in the basics, but in the end the only *real* way to become a good driver is to get out and learn for yourself. And, as with all things, practice makes perfect. So yeah, read some stuff - find out what timebase is, find out what a trigger is, etc. Then after that the only way forwards is to use it on some real life applications.

Without some input signals it gets rather boring, quickly. And the built-in probe calibration signal generator is not very interesting. So my advice is that you grap a couple of transistors, OpAmps, 555th, MCUs, or whatever you like, and build a few signal generators. The web is full of schematics for building simple sawtooth, rectangular, and sine wave generators, with a couple of the aforementioned components.

As much as I love the wonderful equipment reviews, it is especially nice seeing some very relevant theory and applications. Please keep it coming! Excellent post as per usual David.

Plenty of info on the web of course, googling "oscilloscope tutorial" brings up plenty of stuff, some good, some bad I'm sure - but how to wade through it all?

You seem to know your stuff (possible understatement), any advise would be great! First time scope owner, and I'm a cheapskate too. Thanks! Eric very interesting info,
