PC oscilloscope for Linux

Started by Kari Laine February 28, 2010
Hi,

is there any PC Oscilloscope for which there exist Linux software under
BSD or GPL or similar license?

Naturally if the hardware (FPGA) is documented at circuit level - even
better - witch I doubt.

I am even open for self construction kits if they are well documented
and working. They should use Xilinx FPGA though, for which there are
free entry level tools.

Then I must say that Daqarta is very nice product. I have been playing
with it now and I am going to order it by the end of March.
Any users of it know what kind of circuit I could use for the output to
have more current and voltage available, than the sound card can provide?

- op-amp ?
- transistor ?

I don't mind receiving direct mail.

Best Regards
Kari

Thank you for the kind words about Daqarta. In the past, I've had users tell me that it runs OK under Wine, but I have never gotten into Linux myself. As far as output boosting, you can use any audio power amp, from a single chip on up to a rack-mount monster. I have one client whose research required long-duration high-level band-limited noise exposures. I set her up with dual "1000 watt" pro-level amps. (Probably putting out more like 100 watts continuous here.)

There's http://www.knjn.com/Flashy.html which can be paired with any of their FPGA dev boards http://www.knjn.com/FPGA-FX2.html. Source is included for basic setup and data capture. Don't know how hard it would be to migrate it to Linux and gui-ize it. -- Rich Webb Norfolk, VA
