The Square Kilometre Array (SKA), a future radio telescope envisaged to be an order of magnitude more sensitive than current instruments, poses significant calibration challenges. We provide an overview of calibration challenges and discuss current insights in the interplay between calibration and system design. Although further research is required to make quantitative statements on the imaging dynamic range limitations imposed by calibration, we illustrate this interplay by deriving specific
