 The advanced settings for ADC Delay and FPGA Delay are usually not to use. They are mainly for development. In normal user-operation the GUI handles them automatically.

+\TextGrafik[h]{Timing distribution of a KAPTURE-2 Module. The Cascade Clock output of the first Module is used as input for the second modul. One Important information: The PLL is running with internal loopback to achieve a global Delay. This means that one output of the PLL is looped back to the input and by changeing the delay of this output, the complete System is shifted. But it is shifted in the oposite direction: increasing the delay means sampling earlyer.
