Isn't your first example sort of a non-test, since it violates the Nyquist criterion? In other words, isn't it already known that you can't sample a 120KHz signal at 50KHz rate? I.e., it requires a minimum of 240KHz rate. Or am I missing something? I'm trying to do something similar, but at much lower frequencies, using the A/D at 10KHz using a 4MHz crystal. By the way, that World's Smallest Testbench looks amazing. Is there any possibility of an option to reduce the number of input channels for the logic analyzer to increase the sampling rate? It would be nice to get a 2- or 4-channel analyzer running at 5-10MHz instead of the default. I want one when it comes out :) --Andrew _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
