When using the adc121s101 evaluation board with the wavevision capture board, the 5v logic power supply for that capture board is passed to the adc121s101 evaluation board through pins a1, b1, a2 and b2 of j10. However, that voltage is not connected to the power header j6. If it is desired to use th...
Note: be sure to use a band pass filter between the signal source and this board for accurate dynamic performance measurement. 5.2.5 troubleshooting if nothing happens when f1 is pressed, select settings, then capture board settings and look at top for "board properties" if you see "no wavevision ha...
