PC oscilloscope for Linux

[Kari Laine]

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.
