    USB PC Based O-Scope/Spectrum Analyzer/Signal Generator

    I'm looking for a decently cheap USB to PC o-scope that seems to do the job for handling signals and verifying line noise. I'm too cheap to go out and get a Tektronic 3054C like I have at my company and I have to admit I've been spoiled by them.

    What do you guys think about this?

    I would like something to use with sniffing noise and possibly using it to tune with my bitone.1

    As well as any future home electronic projects I may cook up later.

    Any help would be wonderful thanks!


    EDIT: updated title as Chad pointed out something anal prob isn't very appealing.

    anything that's spec'd Anal is all-right by prison standards. :p

    I'd make sure that it is VERY isolated from the computer... unless you are damn sure that you damn well know that on car amps the (-) lead is not ground 50% of the time ;)

    HAHA...i updated the title for your sake and to maybe attract more people since it's less Anal...

    Very true, the (-) is not ground all the time, was just curious how safe it is to use this for when I start putting everything into my car. I guess it's just a nice thing to have if i'm checking signals and such doubled with the fact it can be a spectrum analyzer at the same time. Since i'm already tuning with the bitone.1 using the same laptop.

    well... you can't really plug a mic into it... but you sure can see what the amps are outputting FR wise.

    Yeah I figure I could probably invest in a good RTA setup later. But for now this should do me enough justice for most things...Not just mobile audio
