I am looking for a free oscilloscope program for the PC to run under
Windows XP. Does anyone have any preferences ? It needs to be
quasi-real....not just a toy, but it can be very simple. I have no
need for spectrum analysis and single trace would suffice, but I do
need a calibrated timebase, for example. So far what I have found does
not meet my needs (time axis won't run slow enough, uncalibrated
timebase, doesn't quite work properly on my computer....etc.).

Yes...that one looks pretty good for my needs too. Thanks.
