Hi Luis:I, too, am curious. But I haven't opened it yet. I suspect something like an FPGA feeding a fast a/d somewhere in the 50-70 MHz range. That is, a decomposition. There may be a synthesized LO and mixer to get to the 50 MHz. The info on the website says or used to say something about an sdr modified to act as a spectrum analyzer. One of the things I like about the device that played a part in my purchase is the availability of a 10 MHz reference input. as a good time-nut that shows some serious engineering attention to accuracy.
