Hi

Can anyone help me find circuit for pc-based oscilloscope? not need to be
fast one, I think one can measure up to 100-500Khz it's more then enough.

Regards

Try the dso2100 this work well under 20MHz on osciloscope mode and under
50MHz on spektrum analiser mode.

Hello Tal,

   entirely PC-based (read soundcard) can't sample above the sample rate of
your soundcard (44.1/48kHz).

   A 16FXXX PIC can sample one channel at about 40KSPS (kilo samples per
second) IIRC but maybe the 18FXXX could do it faster.

   Hundreds of KSPS designs involve external DAC and memory but actually
isn't that difficult to do.

   Take a look at http://www.bitscope.com. I have one and I'm very happy with it.
A good software for it can be found at http://www.scopal.com.

   Take a look at PICLIST arquives. This was already discussed here.

   Best regards,

   Brusque
