Thanks to Paul Gittings for leaving a comment with this cool FPGA digital oscilloscope that Jean P. Nicolle from FPGA 4 Fun developed.

“Let’s build a simple digital oscilloscope.

* Single channel 100MHz/100MSPS (100 mega-samples-per-second)
* RS-232 based (we’ll look into USB too)
* Inexpensive!

A simple digital oscilloscope recipe
Using parts from KNJN.com, here are the basic items of our recipe (prices accurate as of this writing, Feb 2007).

* Pluto FPGA board, with TXDI and cable ($39.95)
* Flash acquisition board ($29.95)
* BNC, standoffs, and connectors ($4.95 + $0.95 + $2.95)

That’s about $78.75 so far.”

“Note that since we are using a 100MSPS Flash board, a good idea is to limit ourselves to signals below 10MHz”

Any linux or OS X software for this?

Sorry i dont quote understand, is it really mean same as analog 100MHz osciloscope capability? can it also be use as a spectrum analyzer?

Just map out the serialized cycles in software, usb over rs for sure. Something easy perhaps? I am sure usb signaling currently reside quite high. Compared to what? Well eth0 runs quite hot and using wifi would see a neat little unit. But this unit definitely seems quite novel. Still not sure bout the parity used tho? maybe I will decide.

sorry, “signals”
