Need an oscilloscope...

[So]

I've heard there are PCI cards that I can use to make my PC into a scope... anyone know if that's true and where to get such things? If not, how much is a decent (sufficient for me as a EE) o-scope?

 

[Eli]

I would like to know also.

I've seen stuff on eBay.. software or something, but I haven't looked into it much.

I only just recently got a decent DMM. 😱

Going to produce a standing wave, and demolish a building?

 

[Mrvile]

Demolish the comp first.

 

[TitanDiddly]

Go to a high school that is in a budget crisis, where they have cancelled the electronics courses but still have some of the equipment lying around. You may find many o-scopes lying around in/on top of cabinets, shelves, and in overflow storage. Steal them. :evil:

Well, at the moment, I'm building a class D amplifier for a 400-level EE class, but sure.

Oscilloscopes are for losers, real men buy network analyzers

$144,322 :shocked::shocked::shocked:!

My price range was three orders of magnitude lower.

LMAO!

There are PCI cards, but they are expensive. Perhaps you can find some used ones for a good price.

You probably can find used analog scopes for a few hundred... Digital scopes for more... Why do you need one for home?

I don't NEED one, but as a EE, having one at home would be very nice.

More seriously, good oscilloscopes are quite expensive. I recommend you just test your circuit using whatever your school uses in their labs.

 

[Eli]

I have absolutely no idea what makes an oscilloscope good, or what you need to test amplifier circuits...

But it looks like there are quite a few older units on eBay for under 200$ BIN.

errr what the heck for?

Depends what you're doing with it. You can probably get a 2 channel 20MHz for $50, used.. same deal but 50MHz or 100MHz should be under $200 i figure

But if you need higher freq's, you need to drop teh dollars.

I've been meaning to get a scope.. but if i ebay it I know i'll end up paying out the ass on shipping, so i'd like to find something local

Projects, being able to work at odd hours.

If your school is like mine, there are 24-hour labs available.

Because they're fun as hell? I've had my eyes on an O-scope at school that hasn't been used since they cancelled the electronics classes... In the early 80's.

The man wants to buy more tools. Never try and keep a man from his tools.

Then my school is not. Except for the fact that I have the door code, but I'd bascially be breaking in in the middle of the night. All the building doors get locked, except one that they always forget.

Something like this is probably OK for most of your home stuff..

http://cgi.ebay.com/ws/eBayISAPI.dll?Vi...em&category=45005&item=7504561977&rd=1

I wouldnt buy from that guy though, he doesnt know W(here)TF the capslock key is.

 

[lobadobadingdong]

what frequency's to you need to analyze? I have (I think it's a 400Mhz) scope I haven't used in nearly 2 years. I got a new job and don't need it anymore.

Well, do you have the alarm code? 😛

ATM, I'm only analyzing frequencies in the 600KHz - 1Mhz range.
