    Good software, but the scope isn't very sofisticated and (very important
to me) isn't dual trace. Just samples one of the soundcard channels, or
mixes(add or sub) both channels.

    This isn't a bit limitation for me, as I'm mainly working with low freq
signals. When I need to analyse high frequency, I can use my analog bench
scope.

    The best hardware I know for this is the BitScope (www.bitscope.com),
sadly, the software side of the things is very primitive. I'm wanting to
develop a smarter app for using it, but have no time... :(

    There are other options, like the Mk3
(http://www.ozemail.com.au/~dljones/projects.htm) but I think if I'll need
to buy a digital scope to run with a computer, I'll try the ones from TiePie
(www.tiepie.com). I've downloaded the demo softwares, and it's very good.
Hope he hardware is up to the software. Anyone on this list is using it?

    Best regards,

    Brusque
