I would like to use the 3224 oscilloscope card as an FFT analyzer. The 3224 has only 512K of memory. I am assuming this is what limits the resolution bandwidth of the FFT. At 20 Megasamples/sec it can only collect 25.6 milliseconds of data, or roughly enough to resolve 128Hz increments. Does this sound correct?
I am also interested in using two channels in cross-corellation. Does the FFT software support this?
