This kind of neat. I can shut down the scope, re-start it and the
traces are showing the same as before. I don't have to push every
button on the computer like I had to do with my "real" scope ;-)
It still isn't the greatest thing, but it's a heck of a lot
more "Trusty" than what I had.
The one problem with this type of scope is accurately calibrating
the voltage (vertical) scale. These things (SOundcard versions)
cannot measure a steady DC voltage - it must be alternating to
different levels and at some magical, Minimum frequency.
I am digging it! Especially the price for the ones I have ;-)

Ok, then maybe you should get the USB scope. Because that is
working a
thousand times better than a soundcard - litterally, 50Msps
instead of
50ksps. Working a million times better than the HP scope seems a
good deal
;-)
