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.).
