what do you think about oscilloscope for PC?

Giovanni whispers:
In eBay you are able to find second-hand ones.
The correct group for this is sci.electronics.equipment.

A real oscilloscope is better, IMHO, and cheaper.

ADCs on the market these days and large fast static rams no longer cost

If I was designing one, I'd put in several channels of digital as well as
the lets say 4 analog channels. I very often want to look at what a
signal really looked like when some digital thing was happening. Today, I
usually design test stuff into the circuits to let me make digital stuff
repeat so I can get the scope triggered and snoop around.
Other features I'd like to design in:
After the fact compensation: Getting a probe perfectly compensated is
near imposible. The scope could digitally filter the data to make it as
perfect as can be done.
The waveform changed triggering: I often want to see not what happens
most of the time but rather the funny outlier. Once the scope is
triggering, and making a stable display, it would be nice to have a system
that captures changes.
Never aliasing in the digital scope: I'd patent this idea but it is just
too obvious to stand. For each memory location, there would actually be
two locations. One would contain the highest value since the last sample
and the other would hold the lowest. If the data is undersampled, you
would see vertical bars or a wider trace rather than some alias product.
Many sweep rates: I'd like to be able to have the sweep go at speeds that
are not just simple fractions of a second and have a lot more options on
the rates. In the US having a 1/60th second sweep would be nice, doubly
so if the scope can stack.
Any other ideas?
After I get the work bench in the garage, the shelves done, the pictures
hung, the new drapes up, the funace filter cleaned ..... etc, I may
actually start designing one. At this rate, expect results in about 150
years.

I'me sure good scope equipment for PC is out there. Using maby a bit of
compression even a USB2.0 might be fast enough. That could be cool,
plug, probe and leave
There is an oscilloscope program for linux that uses the sound card at
the fastest sampling rate to scope. But with a sampling rate of 96khz,
its basically for entertainment purposes only (because with nyquist that
means 38khz accurate sampling rate).

Looked good when you changed your audio input to 'CD' then played an audio CD.

I've seen a few oscilloscope programs for Windows. However, they were only good
for 20KHz, audio frequencies.
