any recommendations for a computer based oscilloscope through the sound

If you have an older system that can run real-mode DOS (Win9x or earlier), and you have an ISA-bus Sound Blaster or ESS card, you might want to have a look at my Daqarta package. You can even build your own "card" from a handful of resistors hung on the printer port, if you don't have one of the above cards. It will be only 8 bits, same as many digitial scopes, but unlike the sound cards will go down to DC. See the LPTX driver info on the site.


The Windows version of Daqarta is in the works.

Yes. Don't waste your time and money.

If you're serious about getting accurate measurements, and making an investment in a piece of test gear that will serve you quite well in times to come, poke around for a Tektronix 7000 series mainframe and some plug-ins. For audio and low-RF work, I would suggest the Tek 7603, the 7B53A timebase, and the 7A26 dual-channel vertical plug-in.

Altogether, I'd be surprised if the lot ran you over $100. Good sources for such include ham radio swap meets, surplus test equipment dealers, and Ebay.

Good hunting.

If you wish to construct the PC-based oscilloscope by yourself, please take a look at
