FREE DIGITAL STORAGE OSCILLOSCOPE USING LINUX ON YOUR COMPUTER

[TinselKoala]

Thanks immensely, I have been looking for a tool of just this type. I am downloading it now and will see if it works on my Ubuntu laptop. I have an immediate need for some of its features, but I don't know (yet) how to hook it up. I assume it takes input from the microphone or line in jack. USB input would really be nice. We'll see soon.
Thanks again...there goes the rest of the afternoon!!

Well, the download and install went painlessly, it takes input from the laptop's built-in microphone just fine...nice waterfall display...seems to be very useful potentially. It's a stand-alone executable and as long as you have the prereq packages (which I apparently must have) it just sits in its own directory and works.
But it looks like the learning curve will be pretty steep, and there may still be some problem with my sound card config, as I can't yet get baudline to play back files or clips.

a good freeby for windoze is spectran, it´s not a DSO just a good live spectrogram that is fairly configurable, here it is showing submarine VLF transmissions with 100m of wire straight into a sound card:

Maybe you can ask someone on this site to advise any problem you are having.  Hope it all works out for you.
