Crazyscan2 and TBS 6280
I finally managed to track down a TBS 6280 PCI card that I could use for testing
DATV-Express. A TBS 6220 card would have worked just as well. So above is
a constellation display of DATV-Express transmitting 64QAM with 7 MHz
channel spacing and 2k FFT. It seems that while it does work just with the FPGA
producing the clock it works a lot better with an Si570 fitted. The program I am
using to do the display is crazyscan2.
