A function generator that produces very low jitter speed test signals and artificially generates controlled high jitter signals provides the best testing solution for your DUT. You need a source that produces a clean, low-distortion, stable, and reliable signal to characterise your product in terms of its best performance. You will also need to inject high jitter signals to test the robustness of your product.
