I have a PCI-1411 ,i can use this card to trigger NI5112 to capture a line signal of CVBS output of DVD. And i can see in the graph just a line's wave. But it seems that PCI-1411 cannot trigger the YUV output.The wave display still moves quickly,not just a line signal. Can i use PCI-1411 to trigger NI5112 to capture YUV output sync?
