I am using an AD9625 board (2.5 GHz, 12-bit resolution) and the HSC-ADC-EVALEZ capture board. The data that I am getting from the board using Visual Analog only has 8-bit resolution (as plotted in a Graph component). Register 72 of the SPI Controller software indicates that the resolution is 12-bit. Why am I only getting 8-bit resolution from this board? Are there other registers involved in the resolution of the output data?
