Using Your PC Sound Card As an Oscilloscope in Linux

How do the xoscop read volt dimension?

in terminal type sudo apt-get install xoscope or open your pagage manager find xoscope

grate software works perfect in ubuntu9.10 nvidia soundcard helps a lot figuring defects and analysing signals

Hello,

How must I install this program? What must be typed in the terminal?

Basic sound card goes up to ca. 20 kHz. New motherboards and chipsets go over 100 kHz, but sometimes there is still antialiasing filter cutting off frequencies above 20 - 24 kHz. Lower frequency is low, somewhere 10 - 30 Hz. It is possible to get DC response over a few minutes by reverse filtering the recorded signal. Exact sampling may be alternate times or exactly same time or undefined relationship between left and right channels. I have not enough experience with xoscope, but with similar programs it looks like 1 GHz PC is good enough, even slower. Some other programs, esp. networking may overload even fast computer and cause random loss of one or a few samples now and then. Better to stop other programs when recording something really time-critical signals. Thanks Micaf for the links. (Proofread by Firefox)

@Andreas: Considering the original was created in 1996, I think an Atom 1.6 will be more than enough. You could probably get by with an old Pentium 2 or 3.

What kind of CPU is needed to run this at decent speeds? Say for example, is an Atom 1.6 enough? Thinking about ripping a cheap netbook apart to build a rack mounted oscilloscope.

Thanks. Shame about the petty pedantic people that stumbled upon your guide!

Hi, my only question is that this sound card thing probably has a freq. range from 20Hz - 20kHz.
Am I right ?

Will this work with the microphone input as well?

Thanks Micah!

With the buffer circuit it's as good as a hardware scope, apart from the frequency limitation.

Great, just what I needed, thank you very much

greetings for the site

I've used this before succuessfully with other versions of linux but I can't get it to compile with Fedora 9. Is it possible to compile with an earlier version of gcc?

Thanks

"Do you proofread your text"?

No, this is a blog. That should be enough of an explanation... but... I write this very, very quickly in what very little free time I have. I write this to share information, for free, to the community.

When writing books or articles or papers, yes, I proof read my work and write multiple drafts. When I write on my personal blog, sharing information in my free time, I do not proff red my work. I rely on my readers to put the mistakes into context and determine the meaning and appreciate the fact that I took time to share what I've learned.

That being said, I appreciate emails pointing out mistakes, and if/when I have time, I'll make the correction. But if it's not a technical error I don't give it much priority.

Apparently not

Works! Thanks... I was looking for something like for a while now and... well... I just "stumbled" on it.
