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.).

What is bandwidth required? There is good 'winscope' available free
for
frequencies upto 20Khz.

Bandwidth required is whatever the sound card can provide....so 20 kHz
is fine. But the WINSCOPE I have found (by Konstantin Zeldovich) is
limited to a 50ms scan time. I want to measure time differences of up
to at least 100ms so this is not adequate.

But thanks for your suggestion.

LOL what? An oscilloscope is hardware, what are you gonna do with
software without hardware somewhere? What are you gonna scope with this
program????
I mean you can download a free logic analyzer program, but without the
hardware what's the use?
Here's a free software that lets you control an oscilloscope...

So it's free, and then what??

Sound card !

That could be useful in some circumstances....any suggestions as to
good ones (that don't use serial ports as it has to run on a modern
notebook) ?

You can always use a USB to serial converter.

Bush league amateur stuff! What probe can you use? What can you probe
worth a damn with 20Hz-20KHz? Except audio itself?

Sure, here's the free program. When you're ready, buy the logic
analyzer and stop wasting time with bush league amateur stuff. It's
your time to waste, but life is short.

Sometimes the bush league amateur stuff is all that is needed !

It should not be impossible to get a 100$ FPGA board, generate a VGA display,
use a 100MHz flash DC and have 100MHz logic analiser / digital storage scope
for little more then that plus the price of the probe and a few discrete
components.
Like for example he
