Two weeks ago I started to build a 0-3 Ghz Spectrum Analyser based on Scotty's design.
For more information you can visit his build page.
I first started with the rev. c controller module.
|From left to right: Usb2Lpt Gender changer Controller board rev C|
Since the controller uses an parallel board which modern computers dont't have anymore, I used an Usb2Lpt adapter to talk to the board.
Unfortunately the controller and the adapter are routed for a female plug , so their pins are mirrored.
I could easily fix that problem by soldering a quick and dirty gender changer (the board in the middle).
First tests showed the board is working.
The next step to a spectrum analyser is the phase detector module.
