I was wondering if an ¡°eye diagram¡± display in real-time on an oscilloscope would help in troubleshooting FSK demodulation. As I understand it, the horizontal sweep is driven by the RX baud rate and the vertical deflection is at the analog ¡°slicer¡± (the point where the hard decision (mark or space) is made. Anyway, I think I¡¯ll play around with it. ?
